There are different kinds of milling operations with other cutters. And one such difference is the plain milling and side cutter machine. On the one hand, plain milling is used mostly in the horizontal milling machines. Besides, the shape of the edge is like a disc or cylindrical. And the blades are on the cutter’s outer circumference for milling the plane, which is parallel to the cutter axis. On the other hand, side milling is similar to the flute face cutter. However, its shape, function, and side have a cutting edge that allows it to cut the workpiece’s face & side. Besides, the edge shape is divided into spiral teeth, straight teeth, and staggered teeth. The staggered teeth are suitable for heavy milling.
