cutter compensation values

[Larry Myers]

Hi all

I have been trying to figure out if there is a way to assign multiple cutter compensation values to the same tool, within one program.
Thanks

You can use any offset with any tool, either for length or for diameter comp.

For length comp, you start with:

G43 Z0.1 H01 (MOVE TO Z0.1 AND ACTIVATE OFFSET 01)
G01 Z0 F20.
X2.0
Z0 H21 (MOVE TO Z0 AND ACTIVATE OFFSET 21)
X0

There are parameters in the control that determine how and when the new comp is applied, so be careful the first time through and work above the part.

For diameter comp, I've used one offset for roughing a profile, then another offset for finishing.

G43 Z0.1 H01
D21 F20. (SET OFFSET # AND FEED FOR ROUGHING)
M98 P1001 (CALL PROFILE SUB)
D01 F30. (SET OFFSET # AND FEED FOR FINISHING)
M98 P1001 (CALL PROFILE SUB)

In your sub, you'll have the G41/G42 and G40 commands to turn cutter comp on or off.

Hope this helps.

Thanks Dcoupar

I'll see what I can do with that.

Thanks again,
