The axis soft limit values are factory set for the appropriate work holding and tool holding device fitted at machinemanufacture. Any subsequent alteration in either the work holding or tool holding device will require the soft limits tobe reset accordingly.

NOTE

Before proceeding any further identify the EMERGENCY STOP pushbutton. Firmly pressing this will immediately haltthe motion of all parts of the machine including any optional accessories in use. This button is intended for emergency use only and will cause all automatic machining cycles to be aborted.

NOTE

IntroductionThis tutorial has been designed as a familiarisation and operational guide for first time users of theCNC operations and controls on the Alpha ‘1000' Series lathe.

It is intended to allow users to get the machine up and running quickly, while at the same timeacquaint themselves with the operator controls and the major features of the system.

When reading the text you will find it beneficial to refer to the illustration on page two that identifiesthe keypads, individual push buttons and other controls

Until the commissioning procedure laid out in the Alpha ‘1000' Series manual (supplied with themachine) has been carried out DO NOT attempt to follow the instructions given in this section.

Please ensure that you are fully familiar with the SAFETY NOTES in the Alpha ‘1000' Series manual.

Cycle HHold ppushbutton This pushbutton is operative in AUTO, SINGLE BLOCK or MDI modes. It illuminates when pressed and interrupts the program’s execution. It disables thedoor interlock and the cycle can be re-started at the point of interruption bypressing the CYCLE START pushbutton.

If a block contains axis movement only the interrupt will be immediate. If theblock contains an M, T, S code, execution of the block is completed before theCNC enters the CYCLE HOLD condition.

The following special cases should be noted.

a) If the CYCLE HOLD is pressed during a G76 Canned Threading Cycle, the CNC will complete that particular full threading command before entering the CYCLE HOLD condition.

b) If CYCLE HOLD is pressed during a G92 Threading Cycle the feed light will illuminate immediately but the cycle will continue until the next escape condition of the cycle.

c) If CYCLE HOLD is pressed during a G32 Threading Cycle it will continue tothe end of the -Z (negative) movement and stop. It is advisable to only activate CYCLE STOP if the slide is moving in a + Z (positive) movement

Coolant OOn // OOff These pushbutton manually starts and stops the Coolant Flow. It overrides theprogram codes M13 and M14.

Chuck OOpen // CClose ppushbutton ((if ffitted)This pushbutton opens and closes the power chuck. It will only function when theguard switch is unlocked, allowing access to the work piece, and the spindle is ina stopped condition.

Internal EExternal CChucking SSelect bbutton This is used for selecting internal or external gripping of the component it is interlocked with the OPEN / CLOSED pushbutton.

Handwheel IIncrement SSelect bbuttons This switch is operational in the Handwheel option only. Selection of the X1, X10,X100 position of this switch will adjust the slide movement and the X and Z readout by that amount

The X1 position alters the handwheel increment to 0,001mm The X10 position alters the handwheel increment to 0,010mmThe X100 position alters the handwheel increment to 0,100mm

Stopping TThe MMachineThe machining cycle can be stopped in a variety of ways under normal conditions for various rea-sons, such as checking the surface finish of the workpiece etc.

This can be achieved by a variety of methods as detailed below.

1. To stop machine at any point

2. To resume cycle after Cycle Hold has been initiated.

3. To resume operation after any program stop’ has been initiated.(Program Stops are M00,M01, M02, M30)

4. Emergency SStop BButtonIf a potentially dangerous condition begins, the machine canbe easily stopped by pressing the large red pushbutton.

5. Sliding GuardThe sliding guard is locked during Automatic and MDI operation by means of a spring operated shotbolt. This is a safety device to prevent the guard being opened during cycle.

a) Press Cycle Hold button.

b) Turn the Feedrate Override dial to the off position, i.e. fully counterclockwise.

a) Depress Cycle Start switch on control.

b) Turn Feedrate Override dial to desired override position.

Depress Cycle Start pushbutton.

If you wish to continue, it is necessaryto release the emergency stop but-ton(s) bytwisting to release the latch.Then press the green system on pushbutton until it illuminates and thenpress RESET. Page through theprogram to the point at which the toolwas first called up and then run theprogram from there, in single blockand with extreme care, until you havepassed the block in which theEmergency Stop Button was pressed.

If it is required to stop the machineand open the guard during automaticcycle then depress the Cycle Holdpush-button.

When the spindle comes to rest theshotbolt is released allowing the guardto be opened.

To resume automatic operation closethe guard and push cycle start.

All axes motion ceases unless thread-cutting is active.

As above on feed moves, but has noeffect on threadcutting.

Machine operation continues.

As above.

The ‘Cycle Start’ pushbutton willilluminate and the cycle shouldcontinue.

This suspends all active commands stops the spindle and all machinemotion ceases.

This generates a Cycle Hold and stops the spindle. The pushbutton illuminates when active.

This will remove the interrupt condition, the spindle will start and the cycle will continue immediately.

Operation OOf OOptionsEight (( 88 )) SStation TTurretThese are Vertical indexing, fully automatic disk type tool turrets which mount on a raiser block onthe lathe cross slide. They are driven by an internal electrical motor and can be indexed from theone tool station to the next by use of the manual TURRET INDEX pushbutton or the tool positioncan be selected randomly by use of the T code in the MDI or AUTO mode of operation.

Manual OOperation The TURRET INDEX pushbutton will operate ONLY with the control in the JOG / HANDLE mode ofoperation and with the sliding guard closed. Each time the pushbutton is pressed the turret willrevolve to the next station in order of ascending tool number. 1 � 2 � 3 � 4 etc.The TURRETINDEX pushbutton has a single action and the turret will not continue to index if the pushbutton ispermanently held down.

Operation BBy ‘‘T’ CCode When a T code is executed with the control in the MDI or AUTO mode of operation. The turret willrevolve directly to the specified tool position.

The T code must follow the following 4 digit format T _ _ _ _ where the first two digits are theTool Turret Station Number Selection 1 to 8 and the second two digits are the Tool Offset NumberSelection

T0808 denotes Turret Tool Station 8 working with Tool Offset Number 8T0816 denotes Turret Tool Station 8 working with Tool Offset Number 16

(not usually used)

Erroneous ‘‘T’ CCodes ((when aa TTurret iis bbeing uused)If a Tool Number higher than 8 or an Offset Number higher than 16 is used in the program (suchas a program generated by the Alphalink Cad /Cam system) the Alarm message TOOL OUT OFRANGE will appear on the machine screen. The program is edited with the PROGRAM EDITOR inthe CAD System, using the T codes 1 to 8 and Offset codes 1 to 16.

Where pressing the TURRET INDEX button indexes the turret forward (tools 1 - 2 - 3 - 4) - Pressing and holding thebutton down for more than 1 second will index the turret in reverse (1 - 8 - 7 - 6 ).

Manual OOperation - CClamping aand UUnclamping tthe CChuck.There are three ways of Clamping or Unclamping the Chuck.i) Using the Pushbutton on the Operator Control Panelii) Using the Foot Pedalsiii) In Cycle using M codes

Power CChuck, SSpindle RRotation, SSliding GGuard IInterlocksIn order to avoid dangerous situations the Chuck is interlocked as follows:

Interlock 1 The Chuck will not Clamp or Unclamp in any mode of operation if the Spindle is rotating

Interlock 2 The Spindle will rotate with the Sliding Guards Open in the JOG/HANDLE mode but the chuck will not Clamp or Unclamp

Interlock 3 The Chuck will unclamp or clamp at any time in the JOG/HANDLE mode, providing the Spindle is not Running.

Interlock 4 The Internal / External switch is inoperative when the Chuck is Clamped.

Interlock 5 The Chuck will Clamp or Unclamp at the beginning or end of the program in AUTO,EDIT or MDI modes, providing the spindle is not rotating, with the guards in an Open or Closed condition.

Clamping // UUnclamping AA CChuck UUsing TThe FFoot PPedals ((Option)Opening the sliding guards enables the Foot Pedal. Pressing the Pedal once actuates Clamp, press-ing a second time actuates Unclamp. In either case the chuck will complete its clamp or unclampaction before acknowledging the second command.

The following description relates to hydraulic chucks which are either factory fitted or subsequently fitted by T SHarrison personnel. If another system is fitted by an outside agency please refer to the manufacturers instructions orthat of the agents who have connected the item. It is important to understand that the safety interlocks and featuresdescribed in the following text may not function with another manufacturers control system.

NOTE

The operating pressure of the chuck is machine size dependent. It is preset at the factory to a nominal 20 to 25 bars.The recommended MAXIMUM pressure should, under no cIrcumstances, be exceeded. This figure is clearly stated onthe legend plate below the Chuck Pressure Adjuster situated on the Hydraulic Power Unit. Adjusting it to a HigherPressure will result in the Draw Tube Material exceeding its Safe Tensile Strength Figure, causing the Tube to fractureand the chuck to release the work component.

TheoryThe machine is fitted with absolute encoders on both 'X' and 'Z' axes. Therefore a common"MACHINE DATUM" is used to set up both the 'X' and 'Z' slides automatic "REF POINT RETURN" rel-ative to the TURRET DATUM POINT.

Definitions1. Machine DDatum PPoint

Is the point at which the Spindle Nose and the spindle centre line intersect.

2. Turret DDatum PPointIs the point at which the Face of the Turret Disc and the Pitch Circle Diameter of the VDI tool mounting holes intersect.

3. Ref. PPpoint rreturnIs the Back Stop as Home position to which the "Turret Datum Point" returns relative to the "Machine Datum" when programing a G28.

4. Tool GGeometry OOffset ((Z AAxis) **Is the diametric difference between the 'Turret Datum Point' and the 'Tool Point'.

5. Tool GGeometry OOffset ((X AAxis) **Is the diametric difference between the 'Turret Datum Point' and the 'Tool Point'.

6. Work OOffset // WWorkshiftIs the NEGATIVE dimensional co-ordinate which must be inserted into the control for individualcomponents, to OFFSET the actual MACHINE DATUM to the theoretical WORK-PIECE ZERO DATUM. This enables the user to input actual drawing dimensions.

7. Tool WWear OOffsets **As the heading suggests, these are the incremental offsets which can be inserted to accommodate tool wear in order to obtain component tolerances.

8. Tool-NNose RRadius CCompensationIs the information of Tool Radius and Tool Type which must be inserted into the TOOL GEOMETARY page to ensure the Tool Radii and Tool orientation are correct relative to the component.

* These are not available as standard, but only as an optional extra.

The standard machine features a single ‘OFFSETS’ mode with properties as the ‘TOOL GEOMETRY OFFSET’

Setting TThe WWorkshift

There are 4 variations of OFFSET information which must be considered when setting-up prior torunning the program:

1. WWorkShift The distance in the Z axis from the Machine Datum to the Component Zero Datum

2. TTool GGeometry OOffsets ** Calculates the distance from the Cutting Tool Datum Point to the Turret or Toolpost Datum in both X or Z axes relative to the Work Piece Datum, X zero Z zero. These figures are, usually, numerically large.

3. WWear OOffsets ** Allows figures to be inputted to compensate for any wear to the Tool Tip occurred during the cutting operation without altering the Tool Geometry Figures. These figures are, usually, numerically low (micron's)

4. TTool-NNose RRadius CCompensation Is the theoretical path being generated by the Cutting Tool, taking into consideration the Radiusof the Tool and the Position of the Tool, relative to the component.

Machine AAxesIn preparing a program four characters are used to identify the required slide positioning:

"X" ABSOLUTE (diameter) dimension Associated with"U" INCREMENTAL (diameter) dimension cross-slide movement

"Z" ABSOLUTE (longitudinal) dimension Associated with"W" INCREMENTAL (longitudinal) dimension saddle movement

When using X and Z dimensions, the dimensions are taken from a common datum position and thisis referred to as ABSOLUTE PROGRAMING.

When using U and W dimensions, the dimensions are relative and are taken from point to point.This is called INCREMENTAL PROGRAMING.

Working QQuadrantsThe four characters X, Z, U, W, can be proceeded by a (-) negative or (+) positive sign to deter-mine the direction of that movement relative to the component datum, which ultimately determinesthe machining quadrant in which the tool is working.

Tool FFunctionThe "T" code is a four digit number made-up of two different parts. The first two digits being theTool reference number; the second 2 digits the Offset numbers.

Tool No./Offset No.

T_ __ // __ __ (01-8 ) / (00-16)

Although it is normal practice that the tool number and the offset number are the same this is notcritical and any combination of tool and offset numbers can be used:

Examples:T0100 : tool one with no offsetT0101 : tool one with offset one (normally used)T0114 : tool one with offset fourteen (can be used)

There are four toolpost options available for the Harrison CNC machines:

Option 1 : manual quick-change toolpost (fitted as standard)Option 2 : manual indexing four station toolpostOption 3 : manual angular quick-change toolpostOption 4 : auto indexing eight station toolpost

(i) On the Alpha machines the programing procedure for all the toolpost options is the same.

(ii) With automatic indexing turrets the machine slides will always complete any X and/or Z move to the Tool Change Position before indexing to the programed position.

(iii) With the manual quick-change toolpost, when the slides have reached the Tool Change Position the message "Change Tool and press Cycle Start" will appear on screen.

Although pressing Cycle Start will recommence the cycle it is necessary to press the PROG pushbutton to re-call the program to screen and clear the message from the screen.

(iv) It is essential that the tool offset digits are zero / cancelled ( T0100) on the rapid movement back to the Tool Change Position and only re-called when next working with the tool.

Program WWritingIt is advisable to establish a set programing format as soon as possible. This enables programers,setters and operators to communicate and establish safe working procedures.

Each program can be broken down into sub-sections which contain the relative information necessary to safely produce a complete component.

The PProgram SStructure:

PROGRAM NUMBER

SAFE START

TOOL OPERATION-------- 1TOOL OPERATION-------- 2 TOOL OPERATION-------- 3TOOL OPERATION-------- 4 TOOL OPERATION-------- 5 TOOL OPERATION-------- 6 TOOL OPERATION-------- 7 TOOL OPERATION-------- 8 TOOL OPERATION-------- 9 TOOL OPERATION-------- 10TOOL OPERATION-------- 11TOOL OPERATION-------- 12

PROGRAM FINISH

i) PProgram NNumber

This contains the program reference number which starts with the letter "O" followed by four numbers.

e.g. O0001; (program No.1)

Seperate TTool OOperations

(i) If a Turret is fitted it normally governs the number of Tool Operations which can be used

(ii) Alternatively if a Turret is NOT fitted the Number of Tool Offsets governs the number of Tool operations,

16 offsets are available as standard an extra 32 or 64 as an available as an option

At the end of every block an "end of block" sign must be used, this is a semi colon ‘;’ and is entered by pressing theEOB key.

ii) SSafe SStart

The SAFE START contains all the relative information which sets the machining parameters and conditions. It also cancels all model information within the memory and selects a safe turret indexposition.

e.g. O0001N10 G21 G40G96 G99;N20 G50 S.2800;N30 G00 X500 Z500 T0000;N40 M01;

N10 G21 G40 GG96 G99;(block (metric) (TNRC off) (constant (feed per rev.)number) surface speed)

N20 G50 S2800;(spindle speed (spindle speed restrictionrpm restriction) set to max. Of 2800 rpm)

N30 G0 X500 ZZ500 T0000;(rapid traverse) (X and Z co-ordinates (cancel allfor tool-change position) offsets)

N40 M01;(optional stop)

iii) TTool OOperations ((1-112 mmax.)The TOOL OPERATIONS contain the information of individual tools data and cutting requirementsto perform any sequence of machining.

e.g. N50 T0200;N60 G0 G96 X62 Z0 S250 T0202 M13;N70 G01 X-11 F0.3;N80 G0 Z3;N90 X500 Z500 T0200;N100 M01;

N50 T0200;(tool No.1 without offset)

N60 G00 GG96 XX62 ZZ0 S250 T0202 M13;(surface (tool No.2 (spindlespeed with offset forwardm/min) No.2) with coolant)

N70 G01 X-11 F0.3;(linear feed) (X co-ordinate) (feed per rev 0.3mm per rev.)

Block N70 will face up the bar end if this was the operation required.Block N80 will move the tool off the material.

N80 G00 Z3;

If this is the end of the work that the tool is doing, two more blocks of information are needed to finish this statement.

Block N90 will take the turret back to tool change position.

Block N100 will allow an optional stop to be performed if needed.

N90 XX500 Z500 T0200;(X and Z tool change co-ordinates) (tool No.1 without offsets)

N100 M01;(optional stop)

iv) Program FFinishThe PROGRAM FINISH consists of two blocks of information to send the tool back to tool changeposition and to end the program.

e.g.

N110 GG0 XX500 ZZ500 T0200 M05;(X and Z tool change co-ordinates) (tool 2 without Offset) (spindle off &

coolant off )

N120 M02;(end of program reset to start)

v) CComplete PProgramThe complete program has now been established:

(Between each section it is recommended that two EOB signs are used to separate the sections tomake reading the program easier).

O0001; (Program nnumber);;N10 G21 G40 G96 GG99; (Safe SStart)N20 G50 S2800;N30 G00 X500 ZZ500 TT0000;N40 M01;;;N50 T0200; (Tool ooperation 22)N60 G00 G96 X62 ZZ0 SS250 TT0303 M13;N70 G01 X-11 F0.3;N80 G00 Z3;N90 X300 Z150 TT0200;N100 M01;;;N110 G00 X500 ZZ500 TT0200 MM05; (End oof pprogram)N120 M02;

The above format is used for all the program which making it easy to read and understand byusers.

Auto CChamfer ‘‘C’ FFunctionIn Examples 1 and 2 all the intersection points were programed to produce the desired profileincluding the points of the chamfers.

The Auto Chamfer Function using the ‘C’ value will produce 45 degree chamfers where needed onthe component.

Reference example using auto chamfering

The program for the above profile from points 1-5 would be as follows:

N110 ...N120 X0 ZZ1 TT0202 SS250 MM03;N140 G01 ZZ0 FF0.15;N140 X10;N150 Z-110;N160 X15;N170 Z-220;N180 G00 XX32;N190 X500 Z500 T0200;N200 etc...

If corners 2 and 4 were to have chamfers and corner 3 a fillet, all of 2mm, then by adding the "C"values as shown below the chamfers will be automatically produced.

N110 ...N120 X0 ZZ1 TT0202 SS250 MM03;N130 G01 X0 F0.15;N140 X10C-22;N150 Z-110 C2;N160 X15C-22;N170 Z-220;N180 G00 X32;N190 X500 Z500 T0200;N200 etc...

(i) Other than the addition of the "C" values.the program is unchanged

(ii) The + or - sign given to the "C" value is determined by the direction in which the tool is travelling and the axis is NOT quoted.

i.e. In block N140 the tool is moving in an "X+" direction up to X10 and must also make a "Z-" move to create the chamfer therefore "C" is given a minus value for the Z axis.

(iii) Auto Chamfers are used in the G01 movements.

(iv) Auto Chamfers can only be entered between two intersecting lines so the control can calculate the start and finish points, As shown in diagram below.

Angle IInput ‘‘A’ FFunctionIn Example 3 all the intersection points of the tapers/angles were programed. Using the Anglr ‘A’Function enables easier programing of such components.

The following rules apply when using "A" input:

(i) The "A" dimension is always a positive value and is measured clockwise from the 3 o'clockposition. (See diagram below).

(ii) Any straight line can be programed using 'one' or 'two' values selected from ‘X’, ‘Z’ or ‘A’.i.e. X and A

Z and AA only

(iii) When only ‘A’is programed from the above all three MUST be programed in the next line toallow the control to calculate the intersection points.

(iv) Angle ‘A’ programing is used in G01 movements.

(v) Automatic Chamfer ‘C’ Function can be used with angular ‘A’ Function to program chamfers on the end of tapers/angles.

Circular IInterpolation - GG02, GG03G02 and G03 are used when programing radii.

G02 CCIRCULAR IINTERPOLATION CCOUNTER CCLOCKWISE ((CCW)

(i) The first priority when programing a radius is to ensure that the tool is at the start point of the arc. It can be brought to this position by a rapid (G00) or feed (G01) move.

(ii) G02 or G03 are programed for the direction of the radius.

(iii) The X and Z co-ordinates are programed for the finish point of the arc.

(iv) Also programed in the same line are the I and K values which are the incremental distances from the start point of the arc to the centre point of the radius.

"I" is measured in the "X" axis. (Radius value not diameter)

"K" is measured in the "Z" axis.

(v) The "+" or "-" sign given to "I" and/or "K" is determined by which direction the tool has to travel in relation to the "X" and "Z" axis.

Using "R" in place of "I" and "K"

Instead of using "I" and "K" values when programing radii the "R" function can be used to replace "I"and "K" which makes programing shorter and easier.

** "R" IS THE ACTUAL RADIUS VALUE **

e.g. Line N270 in the last radius example would read:N270 GG02 XX51 ZZ- 444 RR15;

ORN270 GG02 XX51 WW- 66 RR15; ( W = Incremental Finish Position )

(i) Radii values can be either positive or negative in value as a general rule. To decide whether the R has a positive or a negative value the direction the slide is travelling in on the next block must be considered

(a) If the next block is travelling in a -Z direction or a -X direction the R value is negative.

(b) If the next block is travelling in a + X direction the R value is positive.

(ii) The "R" values are included in the G01 moves.

(iii) The two interacting lines of the radius must be at right angles to the radius otherwise G02/G03 must be programed.

(iv) In program block numbers N420 and N430 the final radius does not conform to above note (iii) and therefore must be programed with the start point of the radius (N420) and the finish point with G02 (N430).

Tool NNose RRadius CCompensation: TT.N.R.C.)When turning components with only parallel diameters and square faces Tool Nose RadiusCompensation (T.N.R.C.) is not required.

"Tool Nose Radius Compensation" compensates for the tool tip radius, to allow accurate machiningof complex profiles with tapers and radii.

** T.N.R.C. IS ONLY USED ON THE FINISH PROFILE PASS **

When cutting taper/chamfer and/or radii the contact point of the tool moves and varies its positionaround the tool tip. This will produce small errors in the components size and shape depending onthe tool tip radius amount.

** T.N.R.C. IS USED TO CORRECT THIS ERROR **

In order to do this the control must have four basic facts:

(i) TOOL TIP RADIUS

(ii) RADIUS LOCATION ON THE TOOL

(iii) TOOL POSITION IN RELATION TO THE WORKPIECE AND CUTTING DIRECTION

(iv) THE PATH OF THE TOOL

G76 - MMultipass TThreading CCycleThis threading cycle calculates the number of passes required to produce the programed thread.Straight and taper threads can be programed using the G76 cycle.

Format:-

N... G76 P...(i) ...(ii) ...(iii) Q... R...;N... G76 X... Z... R... P... Q... F...;

First block:N = Block number

P = P value consists of 3 parts, each 2 digits.

i = Number of finish passes (spring cuts) 02 = 2 Finish passes

ii = Tool retraction at the end of thread This is based on the pitch of the thread but can only retract at 90º or 45º.

e.g If a straight (90 deg.) pull out is required 00 would be programed to retract the tool at 45º. The number of pitches relative to the core dia, finish length and tool start point must be considered. Programing example 15 would retract the tool over 1.5 pitches at 45º (see page 97).

iii = Thread included angle.This is for compound threading using one of the following angles: 29;55;60;80. For plunge threading 00 is programed.

Q = Minimum depth of cut. (Value is radial and in microns).e.g.Q100 = 0.1mm minimum depth of cut.

R = Final pass amount.

Second block:X = Core diameter.

(For taper threads this is the core diameter at end of cut).

Z = Finish length of thread, absolute position.

R = Taper amount. Radial value from end to start of taper.

P = Depth of thread. (Value is radial and in microns).e.g. P1250 = 1.25mm depth of thread.

Q = Depth of first cut. (Value is radial and in microns).e.g. Q500 = 0.5mm depth of first cut.

F = Thread lead.

Increasing the value of ‘Q’ will reduce the number of passes made by the tool

Sub-PProgrammingThe machine’s program memory can be divided into two areas:-

(i) MAIN PPROGRAMSMain programs are the complete programs which are normally used to produce components.

(ii) SUB-PPROGRAMSSub-programs are used within the main programs for a particular operation/ routine.

Sub-programs can be used when:-(a) Several components are to be made in one cycle.(b) A section of program is used on a range of components

i.e. Duplicating Grooves, Contours,Part Off Routines

Two "MCODES" are used to CALL and to END the Sub-Programs:-M98 : CALL SSUB-PPROGRAMM99 : END SSUB-PPROGRAM

FORMAT:-

The sub-programs are called within the main programs.

N110 M98 P....(i) ....(ii);

The "P" value used with M98 has two parts:-(i) Number of repetitions of sub-program.(ii) Sub-program number.

To differentiate between MAIN PROGRAMS and SUB-PROGRAMS it is recommended that the following program numbers are used:-

For MAIN PROGRAMS For SUB-PROGRAMSO0001 O1001O0002 O1002O0003 O1003etc. etc.

When the control reads the M98 code it will go to the appropriate sub-program. The actual SUB-PROGRAM is written as normal programing format, but instead of using M02, M99 is used toend the sub-program. After the control reads the M99 code the program will return to the mainprogram at the block after where the M98 code was read.

ii) Program - EExample 224 Using GG10 ooption tto oover wwrite tthe WW/Shift aand TTool OOffsets ffrom pprogram.

Using the W/SHIFT and OFFSET pages is the handy / normal way to set these Offsets. However,these pages are NOT protected by the EDIT key and can be accessed at anytime by anyone. Toavoid any serious occurrence or misuse of the w/shift and tool geometry offsets, they can be hardwritten into the program using the G10 option which over writes the relevant offsets this appliesequally to Wear Offsets also. These G10 options can be integral part of the Safe Start procedureof the programme.

Use the W/SHIFT and OFFSETS PAGES to set the Offset in the normal method (as described onpages 42 to 45). Carefully record this data ready to write it into the Safe Start.

O0100;;N10 GG21 GG40 GG96 GG99; (Safe SStart)N20 GG50 SS2000;N30 GG10 PP0 ZZ-3301.369; ((Work // SShift SSetting DData )) N40 GG10 PP10001 XX17.570 ZZ0.000 RR0.4 QQ3; (Geom OOffset SSetting DDdata FFor TTool 11)N50 GG10 PP01 XX0.005; (Wear OOffset SSetting DDdata FFor TTool 11)N60 GG10 PP10002 XX16.997 ZZ-66.000 RR0 QQ8; (Geom OOffset SSetting DDdata FFor TTool 22)N70 GG10 PP02 XX0.005; (Wear OOffset SSetting DDdata FFor TTool 22)N80 ..... ;; (etc.);N200 GG00 XX300 ZZ200 TT0100;N210 MM01;

‘Tool Geometry Offsets’ and ‘Wear Offsets’ are not installed as standard they are only available as an option.

On Standard machines there is just one single offset mode.

In these cases the following program example is correct:

GeneralA serial interface port complying generally with the RS232C standard is provided and this may beused for bi-directional communication with a variety of external data storage and editing devicessuch as tape punches and readers and computing equipment.

The interface is primarily intended for use with Fanuc devices but other manufacturer's equipmentcan be used PROVIDING THE INTERFACE INFORMATION FOR THE EQUIPMENT IS AVAILABLE.This information is usually provided in the user handbook for the equipment.

Electrical CConnectionConnection to the serial port is made via the 25 pin "D" type connector on the main A.C. Cabinet

This connector follows the standard pin allocation for the RS232C interface which is detailed onbelow and is compatible with the cable provided. The connection diagram shown in the figure willwork for the majority of applications. This assumes that the external equipment uses a 25 pin "D"connector, but if this is not the case, data on the equivalent connections must be derived from theequipment handbook.

To avoid picking up radiated electrical noise, always use a screened cable for this connection asshown in the figure rate.

Caution. Damage can occur if a serial cable longer than the one supplied is used to connect the machine control to a remote computer. The serial interface used is the industry standard RS-232 and the specified maximum recommended length of cable is 15 metres or 50 feet. However with longer linesand connections between devices that may be on different electrical busses, there is a much greater risk of ground loops. These resultant ground loops can slowly heat the circuits and eventually causefailure in the remote computer or the machine control. It is recommended that the ports are opticallyisolated if long cables cannot be avoided. RS-232 optical isolation devices are commercially available.

GeneralThe drawing on the facing page (page 121) shows the Reference Point Return Position in both the‘X’ & ‘Z’ axes for both the 8 Station Indexing Turret and 4 station Tool Post and the point on thespindle from which they are taken, along with the points on the Tool Posts themselves.

In general the setting of the ‘X’ axis is critical whichever type of Tool Post or Turret is fitted. Whenprogramming ‘X’ axis ZERO, the slide must take a drill directly onto the centre line of the spindle /component. The ‘Z’ axis points of reference are only nominal distances which are taken from thefront face of the spindle to the front face of the Tool holder, on a 4 way tool in post, and the face ofthe Disc on an Indexing Turret.

For all machines the Ref. Point Return for ‘Z’ is usually at (approximately) half the length of the bed.

In all cases however it is also important that the Tool Post or Turret are parallel and square in thetwo axes in which they are travelling and to the axis of the spindle centre line

IMPORTANT NOTEYou will appreciate that T.S. Harrison & Sons export machines world wide and that International and Local distributors hold Alpha machines in stock.

It may be that when the Alpha lathe left the factory it was not fitted with a tool post or turret and therefore the SlideRef. Positions were only set to Nominal Positions.

There are many different types and manufacturers of tool post and turrets all varying slightly in specification andsize. It may be that you have requested a locally manufactured tool post which may have been fitted by a local supplier.

In this event the following procedure details how the Ref. Point Return Positions should be set.

The ‘‘Z’ AAxis 11st RReference PPoint SSet-uup PProcedure 1. Set any WORKSHIFT values to ZERO

2. Check and record the ‘Z’ reading of parameters 1240 and 1250. These figures are machine model specific, both parameters should have the same readings

3. Using the ‘CNC Mode’ of operation, press the MANUAL pushbutton to select hand wheel operation.

4. Using a RULE or TAPE MEASURE to establish the ‘Z’ axis 1ST REF. POINT RETURN position. Wind the ‘Z’ axis to the Z axis figure recorded in parameters 1240 and 1250.

Example, Parameter 1240 � X 300000micron � 300.000mmZ 5500000micron � 500.000mm

5. Switch the machine into MDI mode by pressing the MDI pushbutton

6. Turn the Parameter Write Protect ON, i.e. PWE = 1

7. Press the SYSTEMS key, type in 1815 (do not Input) but press the softkey [NO.SRH]. The parameter 1815 will appear on the screen in reverse video.

8. Using the CURSOR keys, cursor to the APZ column on the ‘Z’ axis and type 0 (zero) and press the INPUT key to alter the parameter from 1(zero) to a 0 (zero)The alarm 000 'PLEASE POWER OFF' will appear

9. Power the system OFF at the RED pushbutton, wait until it shuts down completely. Power up the machine.On power up these Alarms will appear:

100-PARAMETER WRITE ENABLE300-APC ALARM X-AXIS NEEDS ZRN

10. Press the MDI and the SYSTEMS keys, type in 1815 (do not Input) .Press the softkey [NO.SRH]. Using the CURSOR keys, cursor to the APZ column on the ‘Z’ axis and type 1(one).Press the INPUT key to alter the parameter from 0 (zero) to a 1 (one)

11. Turn the Parameter Write Protect OFF, i.e. PWE = 0

12. Power the control OFF at the RED pushbutton , wait while it has shut down completely, and power up the machine to establish the settings.

13. To check the REF. POINT RETURN wind the Z slide forward by approx 50mm, complete a move in MDI mode, G28 WW 00.000; . Press the POS key the ‘Z’ figure on screen should read the same as the ‘Z’ figure in parameters 1240 and 1250.

Soft LLimitsSoft limits are generally set to provide safe area's for the tool and slides around the chuck and tail-stock. They also stop the slides reaching their hard mechanical stops, which prevents damage to theballscrews etc.

The 2 parameters involved are: -

1320 (limits 1+)X---------Z--------- See attached sketch

1321 ( limits 1-)X---------Z---------

At power up the machine has to select its mode of Operation, either Alpha or the ISO mode ofoperation. The above parameters are over written at power up from parameters:-

1322 (limits 2+)X---------Z---------

1323 (limits 2-)X---------Z---------

SOFT LIMITPARMETER 1321X= -35000 (Ø35mm)

SOFT LIMITPARMETER 1320X= +300000 (Ø300mm)

SOFT LIMITPARMETER 1320Z= +1035000 (1035mm)

SOFT LIMITPARMETER 1321Z= +115000 (115mm)

The axis soft limit values are factory set for the appropriate work holding and tool holding device fitted at machinemanufacture. Any subsequent alteration in either the work holding or tool holding device will require the soft limits tobe reset accordingly.

As a general rule the X axis soft stops parameter 1322 (limits 2-) X------- value and 1323 (limit 2)X-------- value are nominally set to 5mm (5000microns) before the actual hard stop of the slide.

The Z axis soft stop parameter 1323(limit 2-) Z value is set individually dependent on the Turret orTool post fitted. It is set nominally to give 2mm (2000 microns) clearance between the tool tip andthe front face of the chuck jaw.

The Z-axis soft stop parameter 1322 (limit 2-) Z value is nominally set to 5mm (50000microns)before the actual hard stop of the slide.

The method of changing parameter readings is used after setting the X & Z REF POINT RETURNS:-

1) Power up the machine in the ISO mode.

2) Turn on the PWE (program write protect)

3) Press the SYSTEM pushbutton

4) Press the PARM soft key

5) Type 1322 and press the NO SEARCH soft key

6) Record carefully the figures in X and Z for both parameters 1322 and 1323 and whether they are +(positive) or -(negative)

7) Cursor to either X or Z

8) Type in the new figure required in microns

9) IMPORTANT: - Power Down Turn The MODE KEY To The ALPHA MODE and POWER UP again to turn the PWE to 0 (off)

10) Check the new reading have registered in the parameters 1320 and 1321

NOTEAs the return reference point is fixed, the type of toolpost determines the physical position of the cross slide. Thismeans that the X & Z soft limits may require re-defining (in parameters 1322 & 1323).

Using the POS pushbutton and the (ALL) softkey to make the existing soft limits inoperative, will allow the slides tobe wound to their extremes and the exact "machine position" for the soft limits to be established.

The soft limits can be altered by replacing the existing figures in parameters 1320 & 1321 to +1 and -1 respectively as shown below:-

ExampleNEW EXISTING

1320(limit +1)X -1----------------------------------------(+ 300000) (+300mm dia)Z -1----------------------------------------(+1035000) (+1035mm)

1321 (limit -1)X +1--------------------------------------- (- 35000) (-35 mm dia )Z +1----------------------------------------(+115000) (+115mm)
