Note that tool retraction in this example is to 150 mm on X+ and 100 mm on Z+ from work piece zero, and

not from chuck face, as no order for changing the position is given to work piece zero, which in this example

is maintained in the previous position. ..................................................................................................... 12

G0 G40 G99 X45. Z0. M8 ....................................................................................................................... 13

As you can see, G codes are first placed and then X, Z and M codes. Codes can be also entered in the

following manner: G0 X45. Z0.G99 G40 M8 ............................................................................................ 13

Entering codes such as G96 and G50 in the same line is not permitted. ................................................ 13

In this example we assume that the part is rough machined. ................................................................. 16

As seen in this example, G2 is used to machine radii in clockwise direction and G3 in counterclockwise

direction. .................................................................................................................................................. 16

G Code List ............................................................................................................................................ 21

M FUNCTIONS ...................................................................................................................................... 23

THREADING .......................................................................................................................................... 25

G32 for threading operations, always operate at fixed rpm (G97). ......................................................... 26

When retapping threads, do not release the work piece, do not change the speed and do not change the

start point. ................................................................................................................................................ 26

CANNED CYCLES ................................................................................................................................. 27

At the end of each cycle sequence the machine is always positioned in the position at which this cycle

sequence was started. The tool will be commonly located in the position used for rough machining. ..... 27

The profile allows changing X and Z direction. ....................................................................................... 27

At the end of each cycle sequence the machine is always positioned in the position at which this cycle

sequence was started. ............................................................................................................................. 27

The positioning allows changing X- and Z-axis direction. ....................................................................... 27


Same as the above one, excepting for the profile. .................................................................................. 28

IMPORTANT: Roughing cycles are without tool radius compensation. Because of this, higher allowances will

be specified for X and Z depending on tool radius. .................................................................................. 30

1. EXAMPLES OF CANNED CYCLES .................................................................................................... 31

Groove width or groove end point can be defined with a W code in this example (W27, that is, 30 – 3 of tool),

if tool is positioned on the right-hand would be (W-27). For either Z or W, tool width must be subtracted. 35

PROGRAMMING SIMPLIFICATION FUNCTIONS ................................................................................ 39

In theses cases, considering tool direction is most important. ................................................................ 39

The easier procedure is drawing a quadrant on the drawing and locate the degrees as shown on the above

diagram. .................................................................................................................................................. 39

All cycles end where they are started and, because of this, finishing positioning is done above the workpiece.

47

For control units with capability for machining profiles with X-axis direction reversal, the first block for defining

the profile must state the movement of the two axes. .............................................................................. 49

M98 Repetitions of a subprogram .......................................................................................................... 53

1- Stop the spindle (S1 and/or S2) by entering the command M5 (S1) or M115 (S2) before entering M43 or

M143 command. ..................................................................................................................................... 59

2- After activating M43 C-axis on G28 C0. must be entered . .................................................................. 59

3- After activating M143 A-axis on G28 A0. must be entered. ................................................................. 59

4- Before entering command M40 and M140, the powered tool must be stopped by entering command M15.

M160, M161 and M162 commands are only used on machines equipped with a sub-spindle (S). ......... 90

M160; ............ Speed synchronisation mode on. .................................................................................... 90

M161; ............ Phase and synchronisation mode off. ............................................................................. 91

M162; ............ Phase synchronisation mode on. .................................................................................... 91

1- For transferring a workpiece from main spindle to sub-spindle, main and sub-spindle speed must be

synchronised by means of M160 command. If the workpiece is transferred without activating the

synchronisation mode, damage of the workpiece could result. ................................................................ 91


2- For transferring an hexagonal bar, main and sub-spindle phase and speed must be synchronised by

means of M160 and M162 command, as otherwise the transfer operation will not be possible, although it is

recommended that if the part has been turned that you locate on the turned diameter so to achive any

squareness or concentricity tolerences. .................................................................................................. 91

3- M162 function can be also used for round parts, but considering that phase (and speed) synchronisation

time is longer and speed synchronisation time, using only M160 function is recommended when machining

round parts. ............................................................................................................................................. 91

BASIC CONCEPTS

Machine axes

Z+

X+

X-

Z- B- B+

C+ C-

A+ A-


X-, Z- and B-axis and their respective positive and negative displacement directions are shown on the above schematic diagram.

Y+ and Y- axis are not shown Y- is towards machine bed and Y+ away from the machine bed,40mm+,40mm– to give stroke of 80mm. (machine needs to be on Y zero for turning operations).

As you can see, when workpiece zero reference point is located on workpiece end (most common case), the positive direction is outside the workpiece, while the negative direction is on the workpiece area to be machined (inside the workpiece).

Commonly, you will operate in the quadrant defined by X+ and Z-.

The machine will enter only in X- area for facing operations.

You may also operate X+ Z+ quadrant when the workpiece is clamped on the subhead.

C-axis would be used to swivel the main spindle head inorder to position the work piece for drilling operations using a powered tool.

C+ is in clockwise direction and C- is counter clockwise direction.

A-axis would be used to swivel the sub-spindle head inorder to position the work piece for drilling operations using a powered tool.

A+ is in clockwise direction and A- is counter clockwise direction.


Other axes that could be encountered when programming the machine are

F: feed axis (related to slides) to be programmed when in operation.In millimetres x per revolution when the head is rotating (turning)For example:G99 F0.3 this means “03 millimetres per revolution”.

In millimetres per minute when the head is stopped (MC).For example:G98 F80 this means “80 millimetres per minute”

T: is turret rotation.

R: is radius programming.

S: are head revolutions (cutting speed) This letter is always related to heads.G50 S1000 Rpm limit.G97 S1000 fixed rpm (for tapping and drilling).G96 S200 cutting speed (m/min) for all turning operations.

Cutting speed formula:

Vc= Cutting speedD= Part standard diametern= Rpm limit.

,C: Chamfer programming.,A: Angle programming.

Machines must be at the X home position for turret indexing.

Tool offset

The required offset values must be entered each time tool position is changed with respect to the aforementioned position; if tool position is not changed, entering a offset value will not be necessary as these values are stored in the memory.

Entering tool offset values

There are two ways for entering tool correction values.1st.) Supplied with presetter.

Dn

1000Vc=

Vc1000

Dn=


For machines with presetter, place the presetter in position and preset the tool.2nd.) supplied without presetter.

For machines without presetter, turn the work piece and retract the tool without moving it out the axis. Then measure the work piece and enter the readings in the geometry table.To enter a value, go to the geometry table (offset value), enter the required value and press the intermediate key; by this way the control unit will calculate the offset value.

Workpiece zero reference point

Workpiece zero is the workpiece protruding length from main chuck face.

We advise you to enter workpiece zero at the beginning of the program.

Single spindle machine format

G10 P0 Z-80.

Sub spindle machine format

In the following example we explain how a value of 80 is entered for the first stage G54 (machining the workpiece on the main spindle), while a value of 460 is entered for the second stage G55 (machining the workpiece on the sub-spindle).

G10 L2 P1 X0. Z-80. ;G10 L2 P2 X0. Z-460. ;

Zero 1st phase G10 L2 P1 Z-80

Zero 2nd phase G10 L2 P2 Z-460


How to prepare the machine for machining operations with transfer:

1st Determine workpiece zero and carry out the 1st machining stageG54 is programmed.2nd Stop the machine and verify the dimension before doing the transfer.3nd Do the transfer and place the sub-spindle in working position.4nd Stop the machine and determine workpiece zero before performing the 2nd

Head rotation direction:M3 head rotation direction forwardM4 head rotation direction reverseM5 spindle stop

If instructing the reverse from the forward direction or vice versa, the spindle must be stopped first.This is also valid for the sub spindle and live tools.

G0 X150 Z100Note that tool retraction in this example is to 150 mm on X+ and 100 mm on Z+ from work piece zero, and not from chuck face, as no order for changing the position is given to work piece zero, which in this example is maintained in the previous position.

Polar coordinate interpolation


Polar coordinate interpolation is used when it is desired to perform milling operations on the face of the work piece, which require synchronous movement of the spindle and live tooling mounted on the turret.When polar coordinate interpolation is commanded by the G112, the control interprets several pieces of data to determine the direction and speed at which the axes must be moved to reach the commanded end point.The drawing below shows the coordinate system used with polar coordinate interpolation.The programmed end points are laid out as coordinates on this plane.Note the signs for X and C. The following program examples illustrate the use of this system.

1. The following G codes may be used when G112 is active: G1, G2, G3, G40, G41, G42, G65, and G98.

2. G0 positioning is not allowed when G112 is active.

3. When using G2 or G3, the arc radius is specified using the R word.

4. M40 C axis mode must be active before commanding polar coordinate interpolation.

5. The spindle should be oriented to C0 degrees before commanding polar coordinate interpolation.

6. If machining in the X axis only, do not activate polar coordinate interpolation.

7. The unit of command for the C axis, when polar coordinate interpolation is used, is MM or inches, not degrees.

8. When using cutter compensation during polar coordinate interpolation, the same basic TNRC rules apply as with normal lathe programming. However, the following rules must also be observed:-The tool radius and the quadrant must be loaded into the geometry offset file. For polar coordinate interpolation, the X tool offset represents the centre of the cutter and the tool tip location (Quadrant) will be set to 9.


9. The TNRC start up block (G41 or G42 line) must be programmed after the polar coordinate interpolation command (G112 line) has been activated. For polar coordinate interpolation, the X axis move must be equal to at least two times the tool radius entered in the tool offset file. Program the G40 (TNRC cancel) command before the block containing the G113 (cancel polar coordinate interpolation).

10. Program restart and block restart are not allowed when G112 is active.

11. Specify the feedrate as millimetres per minute.

12. X values are diameters and C values are radii

Cylindrical InterpolationCylindrical interpolation (G107) is used to perform contoured milling operations on the outside diameter of the workpiece. The Z and C words are used to specify the end points of the moves.When using cylindrical interpolation, the C word is programmed in degrees.C is also used to specify the radius of the part in the G107 block which activates cylindrical interpolation.The X word is used to program the depth of cut.

1. The following G codes may be used when G107 is active: G1, G2, G3, G40, G41, G42, G65, and G98.

2. G0 positioning is not allowed when G112 is active.

3. When using G2 or G3, the arc radius is specified using the R word.

4. M40 C axis mode must be active before commanding cylindrical interpolation.

5. The spindle should be oriented to C0 degrees before commanding cylindrical interpolation. The formula for calculating the value of the C word is shown in the following program example.

6. If machining in the X axis only, do not activate cylindrical interpolation.


7. The H word is used to program incremental C axis moves.

8. Machine lock mode MAY NOT BE USED when G107 is active.

9. The unit of command for the C axis, when cylindrical interpolation is used, degrees, not MM or INCHES.

10. When using cutter compensation during cylindrical interpolation, the same basic TNRC rules apply as with normal lathe programming. However, the following rules must also be observed.The tool radius and the quadrant must be loaded into the geometry offset file. For cylindrical interpolation, the Z tool offset represents the centre of the cutter and the tool tip location (Quadrant) will be set to 9.

11. The TNRC start up block (G41 or G42 line) must be programmed after the cylindrical interpolation command (G107 line) has been activated. For cylindrical interpolation, the Z axis move must be equal to at least the tool radius entered in the tool offset file. Program the G40 (TNRC cancel) command before the block containing the G107 C0 (cancel cylindrical interpolation).

12. Program restart and block restart are not allowed when G107 is active.

13. Specify the feedrate as millimetres per minute.

Part Transfer

M160 function is used only to synchronise the main and sub-spindle speeds.M161 function disables the phase and synchronisation mode.M162 function is used for phase synchronisation for the main and sub-spindles.

M160, M161 and M162 commands are only used on machines equipped with a sub-spindle (S).

M160; ............ Speed synchronisation mode on. COMMAND


M161; ............ Phase and synchronisation mode off.M162; ............ Phase synchronisation mode on.

1- For transferring a workpiece from main spindle to sub-spindle, main and sub-spindle speed must be synchronised by means of M160 command. If the workpiece is transferred without activating the synchronisation mode, damage of the workpiece could result.

2- For transferring an hexagonal bar, main and sub-spindle phase and speed must be synchronised by means of M160 and M162 command, as otherwise the transfer operation will not be possible, although it is recommended that if the part has been turned that you locate on the turned diameter so to achive any squareness or concentricity tolerences.

3- M162 function can be also used for round parts, but considering that phase (and speed) synchronisation time is longer and speed synchronisation time, using only M160 function is recommended when machining round parts.


Program with Billet transfer using M160

These functions are used when the workpiece on main spindle is to be transferred to the sub-spindle with the synchronisation mode activated.

Sub spindle machining

EXAMPLE


This should be programmed after machining a workpiece on the main spindle and prior to part ejection. Machining on the sub-spindle is done at the G30 position. The following example shows the basic format required for part ejection.All turning cycles work on the sub spindle but machining is usually done in the X+ and Z+ defined quadrant.Attenton should be paid to cutter radius compensation on the sub spindle as this the reverse of normal turning convention.

Part eject

This should be programmed after machining a workpiece on the sub-spindle and prior to machining a new workpiece on main spindle. It is assumed that the sub spindle is already at the G30 position, see sub-spindle machining section. The following example assumes that the machine is equipped with a bar feed.Ensure that you have the spring loaded ejector fitted.
