I mentioned that I'd seen a similar bug where the arc centers are incorrectly calculated. I reproduced the bug and sent it to SolidCAM back in July and was told it was fixed. I just checked and it seems to still be there.
I made a simple part and set up two operations to cut the two shaped. When I check the arc center point for the large rounded end on both tool paths they are out by .006". The arcs should be concentric of course. This leaves a healthy step in a finished part and isn't acceptable.
Here is a screen shot from my backplotter and the part file (solidworks 2009 + solidcam 2008 R12 SP 2.4) The arc centers should be at X0 Y0, the selected one (in yellow) obviously isn't... |
