Hello All,
We have a Haas VF-2 with a Haas HRT210 rotary. I'm machining a block on 4 sides (AO, A90, A180, A270). Working off centerline of the rotary. The problem is that the posed gcode creates A0 and A180 in the correct orientation but A90 and A270 are flipped. In the attached picture specifically (WCS.jpg) depicts how I have the coordinates set up A0 being the top of the part (the face with the cbores). A270 being the flat face in picture WCS_A270.jpg. Has anyone ran into this problem? Can this be fixed in the post processor application within creo?
Thanks,
Jostan
The only 4th axis programming I've done is full motion milling, rather than indexing.
One thing I had to experiment with that might be related to your troubles is the "Rotary Axis Type" specification in the Option File Generator. Found at:
Applications->NC Post Processor->Type,Specs,& Axes->4-Axis Rotary Table
There are a lot of different options there. Maybe the one you currently have set is wrong? I know this particular setting is very dependant on what type of controller/rotary table you have. Took me a bit of experimentation to get it right for our particular setup, since the rotary table was an after-market addon.
That part is correct. I found the solution. I flipped the the coordinates A270 and A90 to negative values. Then I needed to change the scaling factor from of the A-axis from 1 to a -1.
