A new material classification with MC codes will gradually be introduced by Sandvik Coromant and replace the existing CMC-code system. The MC codes, with further sub-groups, will give more specific cutting data recommendations compared to the CMC material classification.

Medium machiningMost applications general purpose. Medium operations to light roughing. Wide range of D.O.C. and feed rate combinations.

FinishingOperations at light depths of cut (D.O.C.) and low feed rates. Operations requiring low cutting forces.

3. MACHINING CONDITIONS

Good conditionsContinuous cuts. High speeds. Pre-machined workpiece. Excellent component clamping. Small overhangs.

Average conditionsProfiling cuts. Moderate speeds. Forged or cast workpiece. Good component clamping.

Difficult conditionsInterrupted cuts. Low speeds. Heavy cast or forged skin on workpiece. Poor component clamping.

CONDITIONS

ProductivityHow can you improve it? What is productivity?Productivity itself has several definitions, the Sandvik Coromant definition is Output/Input. Doing more with less. The output can be influenced by a number of factors, such as: Selection of machining method and tool path Choice of tool, insert geometry and carbide grade Cutting data (speed, feed and depth of cut) Low number of rejects Fewer tool changes - more machining time Product availability - less inventory Technical training - better understanding

One key factor is the metal removal rate Q, which can be measured as the amount of material removed in a given time period (cm/min).

Turning:Metal removal rate cm/min

ae = radial depth of cut (mm) ap = axial depth of cut (mm) Dc = drill diameter (mm) f n = cutting feed (mm/r) n = spindle speed (rpm)

Q = vc ap fn

Milling:Metal removal rate cm/minap ae vf 1000

General informationCompensation of cutting speed for difference in hardness, HB

Cutting data is given on the ordering pages for the recommended first choice grade in combination with the hardness (HB) in the table.

If the material being machined differs in hardness from those values, the recommended cutting speed must be multiplied by a factor obtained from the table below.

You are using an 80 mm diameter cutter. The cutting speed start value (vc) on the insert box is 200 m/min. Find the cutter size in the left column, and cutting speed in the top row and read the spindle RPM at the intersection: 795 revolutions per minute.

General guidelines:vc

Starting valuefn

To keep chip formation when changing cutting data, increase/decrease both vc and fn.

FormulasCutting speed, m/min x Dc x n vc = 1000vc = cutting speed m/min n = revolutions/min Dc = diameter mm

Spindle speed, rpm v x 1000 n= c x Dcn = spindle speed, revolutions/min vc = cutting speed m/min Dc = diameter mm

Table feed, mm/min vf = n x z x fzvf = n= z = fz = table feed mm/min revolutions/min number of teeth feed mm/tooth

Turning toolsHow can you improve the productivity?If you want to change the cutting speed to obtain higher metal removal rates the new cutting speed values can be calculated from the following table.

Tool life (Mins.) Correction factorExample:

10 1,11

15 1,0

20 0,93

25 0,88

30 0,84

45 0,75

60 0,70

If the recommended cutting speed (vc) = 225 m/min. A tool life of 10 minutes gives you: 225 x 1,11 250 m/min Feed

Note!

When increasing the feed (fn mm/r) the surface speed (vc m/min) should be decreased and vice versa, as indicated in the cutting data recommendations.

Decreased cutting speed %

Example 2 Decreased feed fn, mm/r How to use the diagramThis diagram shows a simple method of adjusting the starting value for cutting speed and feed recommendations. Cutting data on insert dispensers are based on a tool life of 15 minutes and will remain the same with the values taken from this diagram.

Example 1: Increase the feed with 0.15 mm/r (+0,15). Result: Decrease the cutting speed with 12%. 18

Example 2: Increase the cutting speed with 15%. Result: Decrease the feed with 0.18 mm/r.
