Turning Profile Finishing - No Dragging option leads to wrong cutter compensation code (G42 instead of G41)

Tried the no dragging function on a profile finishing toolpath. Looks fine in simulation however gouged material on actual test. 

 

I am using the Wear compensation mode in this case to enable machine side control using wear offsets. 

 

Upon further inspection of the posted code, we found that while G42 is the correct comp cutting along the body up to the shoulder, the no drag creates a toolpath to 'face' the shoulder after a retract move and this move should be compensated G41 instead of G42 which caused a gouge both axially and radially in the material.

 

Does anyone have any idea how to resolve this in Fusion360 itself? While this is a pretty easy fix for this sample part (manually changing the G42 to G41), it's not a feasible solution for future complex programs and also a potential hazard for operators who WILL make mistakes on this.

 

I've added the sample file I have here for reference and also I was using a Doosan Turn/Mill post for the code.

@akash.kamoolkar, Will there be an update to fix this issue soon? I can work around it by selecting "In computer" for the compensation type but I would like to use no dragging with wear compensation turned on in the program. Currently the toolpath gouges the parts with no dragging and wear selected in the toolpath.

Hi to all,

is there any update on this issue ?
