O.k. i have this disk that has some complex profiles that need to be completely cut out. I use the MILL-CAD function and have no troubles here except picking an exact start point. (I have no CAM so thats not an option) What i am trying to do is first drill through the 1" plate with a 7/8" drill then plunge at this location with a 3/4 endmill then do my cut out. My issue is when i choose a line in the MILL-CAD set up does it pierce at the exact location i put the cursor on, or at the begining of that line segment or arc? I was gonna draw a line coming off the profile to the inside for my drill point, but i think this will confuse the control because there will be an intersection at the end of this line and the profile line? I've been playing around on aluminum and don't quite feel comfortable moving into the final steel piece.
I also noticed when using this function, sometimes the whole profile programs, other times just part of it depending on where i start my pierce point, and which direction i go. I have fastCAM for a plasma table (i believe this is fastCAM) and usually when this happens you have double lines or a gap, but this drawing is 100% clean. Any ideas?
