I am practicing with my home student mill (sherline) using machining wax. Using fusion360 (because it is not thousands of dollars) I have been trying out different patterns and tool combinations for a specific challenge, A hemisphere. A simple half ball shape about 1" diameter. This is the shape I find to be the hardest to get a smooth finish on.
About the best I've used so far:
Adaptive pocket to clear the bulk. 1/4" end mill.
Parallel. 1/4" end mill.
Spiral. 3/16" ball end.
This is not giving me the smooth clean lines I'd like. It is all practice and I'll melt it back down. Nothing specific to a job. Just learning the various approaches by doing. Working in wax, really tolerant material that shows the least detail well. When I get done I can see the paths for all 3 operations at one point or another on the hemisphere.
Any advice of tool/operation combinations for a smooth half-sphere? Any tweaks to path set-up you'd use? I'm not honestly certain that a completely smooth half ball is possible with 3 axis and standard bits.
