Background
A milling cutter is a rotating tool with one or more cutter teeth for milling. When in work, each cutter tooth cuts off the allowance of the workpiece in sequence and intermittently. The milling cutter is mainly used for processing planes, steps, grooves, forming surfaces and cutting workpieces on a milling machine, and cutter teeth are distributed on the circumference of the milling cutter and are divided into straight teeth and spiral teeth according to tooth profiles. The teeth are divided into coarse teeth and fine teeth. The helical tooth coarse-tooth milling cutter has less tooth number, high cutter tooth strength and large chip containing space, and is suitable for rough machining; in order to ensure that a sufficiently high average chip thickness/feed per tooth is used, the number of cutter teeth suitable for the process must be correctly determined. The pitch of the milling cutter is the distance between the active cutting edges. The milling cutter can be divided into 3 types, namely a dense-tooth milling cutter, a sparse-tooth milling cutter and a super-dense-tooth milling cutter according to the value;
