In screw rotors manufacturing, milling machining can be conducted by using a disk-like form-milling cutter. Design method of a disk-like form-milling cutter with multiple inserts applied on screw rotors machining for twin-screw compressors were presented in this study. An analytical calculation procedure of insert arrangement on the cutter body profile was constructed. Subsequently, the screw rotor cutting simulation was performed by considering the actual cutting conditions based on a horizontal CNC milling machine’s established coordinate system. Finally, the simulated rotor profile could be obtained and the normal deviation was evaluated.
