The milling cutting is essentially positioned "face down" towards the top of the workpiece. When engaged, the top of the milling cutting grinds away at the top of the workpiece to remove some of its material. What Is Peripheral Milling? Peripheral milling is a machining process in which the milling cutter is placed parallel to the workpiece.

For plain milling operations, a plain milling cutter should be used. Deeper cuts may generally be taken when narrow cutters are used than with wide cutters. The choice of milling cutters should be based on the size of the workpiece. If a wide area is to be milled, fewer traverses will be required using a wide cut.

The form milling is the operation of producing the irregular contour by using form cutters. The irregular shape may be convex, concave, or of any other shape. After machining, the formed surface is inspected by a template gauge. Cutting rate for form milling is 20% to 30% less than that of the plain milling.
