The plain milling is the most common types of milling machine operations. Plain milling is performed to produce a plain, flat, horizontal surface parallel to the axis of rotation of a plain milling cutter. The operation is also known as slab milling. To perform the operation, the work and the cutter are secured properly on the machine.
