Plain milling is a common operation in milling machines, where the axis of the cutter is parallel to the surface being milled. This operation, also known as slab milling, produces a flat, horizontal surface parallel to the axis of rotation of a plain milling cutter. The work and cutter are secured on the machine, and the depth of cut is set by ...
