I use flat geo and the toolpath parameter automatic roll it for me. where do I change it to -90 ?

 

If I roll GEO first ( set a positioning to -90 as you said ) and then the backplot look ok but in Verify and NC file off -90 deg.

 

If you need the file I will send it to you to take a look.

I just wanted to let you guys know I cut the part today and thanks to you guys it went great. I basically just re-did the whole thing using the Johns' (Paris and Summers) advice. The roll was only 33" but I was using 36" so it would start off the part, but by using the unroll/axis substitution I was able to make a more accurate drawing. One problem I did come across was the tool was centered in the Y axis and wasn't cutting on the edge but rather the center of the tool, so the tool was essentially plunging the whole time, which caused all kinds of chatter and flex. To fix it, I offset the tool .3125" in the Y so it was cutting on the front edge, as it would be on flat plate. Things went MUCH better after that, and I even increased my depth of cut, making a faster job of it. I'm not sure what you guys do, but that was my fix. Thanks again for all your help everyone!
