Mike,
The issue that I've been having on and off for the last year was an incorrect representation of the workpiece when machining a non-cylindrical complex part in a continuous or indexed 4 axis set-up when the workpiece was a cylinder. I always just ignored the simulation result when this happened but studied the toolpath to make sure that the part would cut correctly. I never understood why others weren't complaining, and I did get one reply from Yuri about a year ago that they were able to repeat the problem on the project I sent him and that they would fix it. Well, last week I ran in to it again but this time the toolpath was too complex for me to interpret the final result and so I posted my question. It wasn't but a few minutes after my post that I noticed a new window on the simulation page with an option for selecting the type of simulation- solid, voxel, voxel 5d. I didn't even understand what these terms meant but since I had tried everything else in the previous few hours wrestling with the machining page parameters to fix problem, I changed the type of simulation and suddenly the problem went away. It turns out that this selection has to agree with the simulation type selected on the machining page but in my case the defaults were coming up different from each other. And since I never paid attention to this before, it was screwing with the simulation results. I don't know if this has been my problem all along or if there was another separate problem, but its working fine now. By the way, I'm a few weeks from finishing that Howell V-4 engine that I've been working on for 2 years. I'm sure I have some 3000 hours of work into it. I'll post some pictues over on the Tormach site when its done and running. - Terry  |
