Implementation of the Method for Machining the Worm Threads by a Face Cutting Head at CNC Lathe

Bogdanov K.V., Khvatov D.A.


The paper considers the version of practical implementation of the method for preliminary machining of worm threads with application of a cup-type multi-cutter tool equipped with standard replaceable hard-alloy plates at the CNC lathe. The description is given for the scheme of modernizing the lathe and layout of the standard finishing double-sided face head for cutting of gearwheels with circular teeth. Basic requirements to modification of the CNC lathe and the gear cutting head are stated. Fundamental relations for calculation of generating parameters and methods for calculation of machine-tool settings are presented. The results of preliminary cutting of worm threads by the proposed method are demonstrated.
