Hi Scott,
Nice to meet you We are actually just getting ramped up with Sum3D and have not done too much tweaking, outside of feeds/speeds/z-increments. To answer your questions:
1. Currently not using 'climb mill' at all...just bidirectional.
2. We use <SLOPE2> on our internal and external roughing passes. Do you see better results from a higher angle?
3. We use 0.1mm oversize for internal/external roughing, and .05mm for the crown roughing. So far, we haven't seen much chipping at all, minus the occasions when tools wear out, but you make a good point. Nothing more frustrating than seeing chipped units after a long build
4. We are doing 0.05mm steps for 2mm, and then 0.1mm steps after that (<SPIRAL0/2/0.05><SPIRAL2/0/0.1>). Again, we've been getting great fits, so haven't been compelled to change this around too much.
Most of our effort is towards quicker mill times and better-looking full contour anatomy. I think the 0.3mm burr will help reduce manual finishing. For speed (hey Nicely ),we are ~27min for full contour, and ~18min on substructures. This is without the sprue reduction.
We are going with pretty aggressive roughing at 0.7mm z-steps, then switching to 0.05mm steps for finishing. So far this has worked ok, but I think we may be killing the 2mm burr a bit quicker. I'm trying to do some burr wear tests, but it's expensive and takes a while.
