Construction method of multi cylinder milling enveloped single screw compressor tooth face type wire

The present invention discloses a method for forming polycylinder milling enveloped monoscrew compressor tooth-face profile. It is characterized by that said invention adopts a polycylinder milling cutter with different directions to repeatedly cut same tooth face generating line of screw rotor, so that it can implement polycylinder enveloped profile of this monoscrew rotor tooth face, and provides the mathematical description of this screw rotor profile. Besides, said invention also provides the characteristics of said profile and its machining method and steps by using said polycylinder milling cutter.
