Hi users- I've got a strange one. I created a mfg session using an indexer. I set up my machine as a mill 4 axis. I programmed it fine and just before lunch I verified it in vericut and posted it. Everything loked really nice.During lunch I decided to do a seperate turning operation. I defined a lathe 1 turret op-2 and started to program.After lunch I made a depth change to the milling op and reverified and posted it. Vericut showed the process but no material was removed and the posted output was not in the correct format.I then realized the machine for this op had chaned to a lathe. I've tried to change this in the past manuaally but it won't let you. I rolled the mfg file back 1 hr with no change. I then rolled it back another 1/2 hour and everything is fine. Vericut shows metal removal. The machine ia a mill 4 axis and the posted output is the correct format. I'm trying to think of what I did wrong but I don't think I did. Restarting Pro did not help. I had to remove 12 mfg files to get back to my proper place. A virus scan has not turned up anything yet. Any insight would be appreciated.
