Could you please clarify this a bit?
If you program a 360 degree arc and it cuts less than 100% of it, how would you program it to do so.
I'm not sure I understand what you are referring to here, as I use cutter comp and have never had a Dynapath cut an inside or outside diameter that did not cut 360 degrees of arc when programmed to do so. I use G-Code, not Conversational.
If I program a 1" bore, I program the tool path for 1" and use comp to offset the tool by it's diameter. If the diameter ends up .999", I adjust the tool diameter in the tool table by .0005" so it cuts 1" diameter.
I have never programmed an offset tool path and then used comp to adjust the cut diameter such as explained in the manual as "Negative Cutter Radius Compensation". If this is what you are referring to, I assumed it was to be used to make relatively small adjustments. 1" is a pretty large adjustment!
Do you thread mill with the Dynapath?
