Need Help!- Is it possible to G41 a complete circle, ID?

[BigC]

Want to run tool comp while circle interpolating a bore. So I can sneak up on it with tool wear comp D. Cutter comp moves after entry moves cause 367 alarm cutter comp interference. I know I still struggle w/ CC moves as simple as the feature seems but I've tried doing different things to try to fool it and still can't do what I want.
I can do this with G13 but feel I am wasting moves going back to center. I am profiling a bore with many mini Z moves.
Any Ideas? Thanks, Jack

Have you tried something as simple as turning comp on in your first Z depth move, then just leaving it on? Just make sure it is a G01 move, and it should work

Give it a dummy move at least the length of the dia. of the cutter before you start to interpolate. A lead in move would work either an angle move or radius.

Sorry that code is for a 1.00 Dia. circle x .500 deep

[dcoupar]

Try the following... put 0.25 in D01 Geometry offset

(INTERPOLATE 0.75 DIA CIRCLE AT 0,0)
T01 M06 (LOAD 1/2 EM)
G00 G54 X0 Y0 S5000 M03 (POSITION TO CENTER)
G43 Z0.1 H01 M08 (RAPID TO CLEAR)
G01 Z-0.5 F10. (FEED TO DEPTH)
G41 X0.375 D01 F5.0 (FEED TO RADIUS - APPLY COMP)
G03 I-0.375 (INTERPOLATE CIRCLE)
G01 G40 X0 (FEED TO CENTER - CANCEL COMP)
G00 Z0.1 (RETRACT TO CLEAR)

G03 I-0.375 (INTERPOLATE CIRCLE)

you can also add a "Z" and "L" values on this line if wanted to interpolate XYZ simultaneously. "Z" being depth per circle, and "L" being how many times you want to interpolate/multiple depths. say you want to take .125 deep cuts going 1 inch deep

G03 I-.375 Z-.125 L8

Thanks, ya'll. I'll give these different ideas a try. I appreciate the quick response. You've all given me some things to think about. Always trying to enhance my knowledge base! Thanks again for being here!
