STUDY ON TECHNOLOGY OF CNC WHIRLWINDENVELIOPING MILLING FOR SCREW

摘要

Whirlwind enveloping milling is a high-efficient machiningrnmethod for screws. Aiming at a single screw, double-headsrnpump rotors which is high in quantity supplied, this paperrnintroduces the basic principle of inner whirlwind envelopingrnmilling technology, studies an arithmetic for spatial pathrnwhen the centre of cutting tools moves relative to workpiecernto envelope helical surface, and analyzes the primaryrnparameters influencing on machining process by example.rnThe method will improve the machining efficiency andrnmachining accuracy greatly.
