Contour CCW,CW,CCW no G03 only G02

[Mike Geary]

I have programed a slot on an outside contour. The outside contour had a 1-1/2" rad.CCW chained to a 2.343 rad.CW and chained to a 1-1/2" rad.CCW. Using a 3" dia. tool, comp in computer and control is left the 1st arc has no G03, then it goes to a G02 and then on the last arc no G03. Note the small arc is about 31° total distance and the large arc is about 303° total. How can I use wear comp if I don't have a G03?

Are you using lead in/out? You need a linear movement at the beginning to compensate the radius of the tool.

Mike, turn off comp in computer. this will generate a g3 move. I don't know what controller is on your machine, or how offsets are handled, but you should enter an offset in the control of 1.4999 for this tool to start, and do a dry run to make sure it doesn't give you an alarm. if this works, then you just change the offset in the control to adjust for wear on the tool. the only other options are to change the radius of the geometry to 1.501, or change the dia. of the tool to 2.999 hope this helps

Yes, perpendicular 25%

does this mean don't use wear?
