What is the subtractive process where a rotating cutter removes material?

Explanation:
Removing material with a rotating cutting tool is milling. In milling, the cutter spins and bites into the workpiece to shear off chips and shape features such as pockets, slots, and holes. This can be done on manual mills or CNC milling machines, using tools like end mills or face mills to create precise profiles and surfaces. This is different from turning, where the workpiece itself rotates while a cutting tool moves along its length, and from soldering or powder coating, which are joining and finishing processes, not material removal. Milling is the go-to subtractive method for producing complex shapes and flat or contoured surfaces.
