When machining a 3D surface with a variable curved profile, we will have to use a ball-end milling cutter. With this type of cutter, depending on the position of the tool's contact with the machining surface, the size and direction of the cutting force, cutting speed, cutting temperature, etc. will be different. The cutting speed varies from maximum to zero at the tip, so in the vicinity of ...
