Hi guys,
I'm trying to generate GCode for a 5 axis machine - XYZBC, table-table.
Whether I generate GCode with TCP support or no TCP support, I get :
- Big weird oscillation on joint axis - around 0.4mm amplitude on X, Y, and Z joint.
- Small erratic oscillation, like on Y and B axis of around 0.05mm/0.01deg.
You can see below the raw GCode G01 position for one circle projected on a dome (Full path seen below) :
My setup :
- Solidworks Premium v2021 SP5.1
- Plugin HSMWorks v2024 R0.44173 / Post-Processeur v4.5940.0
- RS-274D Sample Multi-axis Post Processor / révision 44023 / Slightly modify to add specific retract position because of the layout of our machine.
- Milling of a simple dome while keeping tool normal to the surface :
What I've tried :
- Playing with different function : isoparametric curve / Multi-axis contour following an esquisse path.
- Playing with function parameter, on the 4th tab : "Tolerance" / "Maximum Segment Length" / "Maximum Tool Axis Sweep"
Result :
I keep having oscillation or erratic motion on the joint, whatever the parameter cited is set to.
I feel like the FAO/Post-Pro/Kernel is not able to calculate the proper approximated path.
My Question in priority order :
- How can I mitigate/cancel this effect ?
- Why is it doing this ?
Thanks in advance for any help !
