Fusion 5 axis operation problem with G-code

[Colin]

Hello,
After succesful 3D adaptive clearing

with the same work offsets

I want to do “steep and shallow” operation with 5 axis machinnig option together with automatic collision avoidence:

despite in fusion simulator everything looks ok

in kinematic control simulator
toolpath position is not related with work offset, moreover automatic avoidence add to code three extra commands:
N75 G6.2 X-42.791 Y-52.651 Z15. I1 J1 K0 P1
N80 G6.2 X-42.791 Y-52.651 Z15. I0 J0 K1 P1
N85 M428
which cause abnornal A axis rotation at the beggining, collisions and tool movement z-axis also differs in comparison to fusion simulation

when I turn off collision avoidence option there is a lack of this three lines and everything is correlated with work offsets,

but generated g-code is the same as for 3-axis and cause collisions between stock and toolholder. Please give me any advise how to manage with this.

Regards

You can’t use A work offsets. You need your Setup in Fusion 360 to align with the axes when A is at 0.

Even B work offsets will only work with a new enough version of Kinetic Control. I recommend updating to the latest if you need to use them.

Sorry but I am a begginer and I don’t understand why I can’t use A and B work offsets when it worked correctly for adaptive clearing. Do you also mean that in Fusion

i have to position stock in the same position and orientation as it is on my first image?
Is it obligatory only for 5 axis operations?

If A was commanded to 0 for the adaptive clearing then it didn’t do any transformations and it would behave as you expected. Unfortunately, the math doesn’t work out when using RWO and TCPC with work offsets to use A work offsets once you start changing the orientation of the part.
