Limiting B axis angle on Hurco VMX 42SRTi machine

[Ashley.Moran3CQFT]

Hello Everyone 

Is there a way to limit the angle when doing multi axis machining as fusion seems to want to go to an angle that the machine isn't capable of, or maybe i'm using the wrong tool path?? 

The part has a wrapped slot around a cylinder with straight sides and Im using swarf mill with selected contours, It generates the tool path but wants to B 91.5(approx) Whereas the machine has a limit of 91 degrees. This is set in the machine setup so i get an error when posting 

Is there a way to limit one axis as I know the feature can be produced with the B axis locked at 90 degrees or is there another toolpath that I should be using 

Thank you

I typically would machine that with 2d contour with wrap, but that may not get you exactly what you need.

I suspect the swarf is going to that angle only on the leadin/lead out, you may need to play with the leadins and maybe the entry point to avoid the machine travelling out of limit
