hello all im currently uing a kia superturn 28 with a fanuc controller and ive run into a problem regarding trying to cut an inverse angle using a g71 canned cycle. for ex (cutting / as opposed to \). first ill show you my trial program then explain what it is doing.

Basically instead of breaking up the machining of this piece up into the depth of cut specified (0.075) it tries to cut the whole angle at once. I had someone tell me to add a Z0.05 on the N101 line and removing the Z on the N102 line he got it to work on his machine. he was using a HASS. i tried that myself but i kept getting an illegal g code alarm. if anyone knows how to accomplish this on a kia it would be greatly appreciated. as of now i use that canned cycle but manually change the offset on the X geometry of the tool being used and make my own depth of cuts. on smaller pieces i use a g72 canned cycle with a groove tool to do such an angle. there must be a way to get a turn tool to do this on my kia. any insight on this matter would be greatly appreciated.
