I'm using SolidCAM 2008 SP2.4 (the latest as of last week). I have a simple part that I need to thread mill, when I ran the generated program I got partial threads only on one side of the shoulder.
Looking at the g-code for the two operations that finish the OD of the boss that I want to thread, and the thread milling step I see something obviously wrong.
The boss should be at X1.75 Y-1.75. The operation that finishes the boss has its arc center at exactly that point.
The thread mill operation has the center off by roughly .012" on the y-axis (in different directions for the top arc and the bottom arc no less).
If you look at the screenshot in the backplotter you'll see what I mean.
Part accuracy is set to .0001 (default is .004)
Part of it at least seems to be the post, if I use the haas_3x_nosubs post that comes with solidcam it is only off by .003" and it generates a single move using IJ instead of two arcs using R.
Has anyone ever seen this?
