Hi,

I'm traying to do profile cutting. All going good unless i traying to do finish pass with "control"  compensation. I see wrong trajectory on Fusion and i see different  trajectory on cimco when tool cutting last outer radius.

I trayed different parameters, but can't find right. What I'm doing wrong?

That toolpath would be the tangent tip of the tool along with the compensation direction (?3?). Seems right.

Here is two examples how machine sees the code.

"Red" is from fusion and "Green" is from machine (hand writhed).

 

When operator puts compensation to R8 (insert is ∅16mm) fusion cod throws "041 Interference in G41/G42".

Hand code reads R8 normally.
