App description

Milling is a machining method that uses a milling cutter as a tool to process the surface of an object. Milling machines include horizontal milling machines, vertical milling machines, gantry milling machines, copy milling machines, universal milling machines, and bar milling machines.

Features:

① Each tooth of a milling cutter periodically participates in intermittent cutting.

② The cutting thickness of each cutter tooth during cutting is changed.

③ The feed amount αf (mm / tooth) of each tooth represents the relative displacement of the workpiece during the time that the milling cutter rotates one tooth.
