Title:
POLYGON MACHINING DEVICE AND POLYGON MACHINING METHOD
Document Type and Number:
WIPO Patent Application WO/2014/156729
Kind Code:
A1
Abstract:
A polygon machining method whereby first polygon machining is performed on a workpiece held by a main axis, by using a polygon cutter attached to a tool main axis, then machining using a tool other than the polygon cutter is performed, and second polygon machining after said machining is performed, using the polygon cutter. The polygon machining method comprises: a synchronized stopping step in which the main axis is stopped at a predetermined prescribed rotation position, in a state in which the main and the tool main axis during polygon machining are synchronously rotated when the first polygon machining has been completed; a synchronization release step in which the synchronization of the main axis and the tool main axis is released when starting machining after the first polygon machining; a main axis stopping step in which the main axis is stopped at a prescribed rotation position when the machining after first polygon machining has been completed; and a synchronization starting step in which the main axis and the tool main axis are synchronously rotated when starting second polygon machining.
