Form milling is a type of CNC milling operation of producing irregular contours consisting entirely of curves or of curves and straight lines, at a single cut with form milling cutters. Milling cutters play an important role in the milling process and they are used in several milling machines . Some of the common . This operation is accomplished by using convex, concave, and corner rounding milling cutters. Answer (1 of 2): In gang milling, a number of milling cutters are fastened to the arbor to suit the profile of the workpiece to be machined. Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a workpiece.This may be done varying direction on one or several axes, cutter head speed, and pressure. Milling machine is a versatile machine on which we can perform most of machining operations. Cutting rate for form milling is 20% to 30% less than that of the plain milling. Unlike cutters and drill bits, end mills have cutting teeth on the sides and end of the mill. This is in stark contrast to face milling in which the very tip of the cutter presses against the workpiece. It is the process of machining special contour (outline) composed of curves, straight lines, or entirely of curves, at a single cut. Profile milling creates an exterior contour with a desired shape.
