i was wondering if anyone has any issues with grooving in v26, if i have comp on g41 it will kinda work, i have a groove with a .01 rad on each side, it will cut the left side, but wont cut the rad on the right side, if i change it to computer comp it blows right through the groove, any suggestions? also we have a few dual turret lathes and i was wondering how other people do the posting, im guessing i will have to manually enter the P codes? any ideas on that much appreciated also. i have attached the file, i am running a unlocked demo version, still waiting for our hard copy to arrive in the mail, so not sure if that will make a diffrence, i just changed it to .dwg, rename the file to .bbcd and it should open

I'm currently going thru the same issue. It seems that bobcad-cam is only capable of taking one side of a grooving insert into consideration when generating the toolpath. I'm currently waiting on tech support to get back to me on it. I've seen this question posted on other forums where bobcad reps frequently answer questions / plug their products but nobody ever touches this issue. Why?

After a week of going back and forth with tech support I still have no answer as to why bobcad is unable to generate a usable groove path. The tech guy kept telling me it looked great in the simulator even though the numbers in the post don't add up. Then he says when he zooms in on the sim he can see the undercut/step im talking about. I pointed out the numbers in the post that are causing it to undercut and he tells me he does not know how to read g-code! How are you working tech support for a computer aided machining system and don't know anything about g-code programming? Anyway... that aside he convinced me he'd have someone else look at it with him and he would get back to me. I just spoke with him today and all he did was draw a representation of the groove tool, plot points along the toolpath at the posted numbers, and line the theoretical tool tip along with the drawn tool up to the plotted points which did nothing to solve the toolpath. All it did was prove that the calculated path is still wrong because now you can actually see the tool representation overlapping the part geometry where it undercuts. The we go through changing the system tolerances all the way down to .0001 (the lowest it can go) and re-calculating and re-posting it all and just gives the same bad toolpath. His final statement after wasting all this time is that he still doesn't understand why this is happening and he will try some more things with somebody else's help.

This issue has caused a lot of wasted time and effort already and I feel as if bobcad-cam might just be that. A waste of time and effort. If anybody can prove me wrong (and I sincerely hope someone can)
then please do. I'm attaching the file with the tool representations in the layers here so anybody can take a look at it. If this problem cant be solved and bobcad-cam is incapable of producing usable toolpaths in their lathe module then my company will be seeking a refund or to sell our software and seats to somebody who doesn't mind having a cam system that puts out paths that need to be completely re-written by hand.
