Hello!
I am new to cnc world. have just started a robotic workshop and would like to cnc mill a jewelry box with a lid that has a shape of a hemisphere.
I would like to hear from the experts about the strategy to make tool paths. both roughing and finishing.
I was thinking first mill and finish the inside of the hemisphere, then rotate stock, fix it with correct coordinates and then mill the outside, with some bridges left to hold the piece.
How would you go about milling a hemisphere with let's say 50 mm diameter and a thickness of 8 mm. The material is gonna be cork , so any thoughts on feeds and speeds and type of endmill and ballmill is highly appreciated.
Best regards
Shahrokh
