Try the changes in red above. You're not showing the whole profile so something else may be going on also. You cannot apply cutter comp on a rapid move (G0). I added the X move in red on the first line only because that is my convention for entering a profile with cutter comp. Also, you cannot invoke cutter comp on a radius move. Paul

If I'm using cutter comp G41 to chamfer the OD and face a part in one pass, why does it almost always dig into the OD and then start the chamfer in Z+ to Z0 then face in X-. If I'm going the opposite direction G42, starting at Z0 and chamfer X+ Z-, .
The thing is: because endmills have certain diameter, the center of the tool must be always offset by its radius. . is to program to the finished profile and tell the CNC machine to offset the toolpath by the radius of the cutter. . , There is D55 code in the same line as G41 G41 D55 tells the machine to apply cutter radius compensation .2D cutter radius compensation to 3D cutter radius compensation 3D cutter radius compensation = extension Continuous change in the tool orientation Continuous change in the offset direction Definition of the offset direction as a vector in space 2 ½ D cutter radius compensation = conventional Contour, center-point path of cutter
Control is fanuc 31i. The machine is completing a full circle and returning to the start point instead of moving 180 degrees to the programmed point. This only happens when G41/G42 is active and the tool radius offset is not equal to zero. It makes no difference whether I/J, positive R or. I am using a G71 roughing cycle and turning on cutter comp when using the G70 finish cycle. I faced the part at Z0 in the program before the G71.
