Title:
CONTROL DEVICE AND CONTROL METHOD FOR MACHINE TOOL
Document Type and Number:
WIPO Patent Application WO/2021/177450
Kind Code:
A1
Abstract:
An oscillation component a sin(Mωt)(where M is the number of surfaces), which reaches maximum at the point in time at which a tool cuts the center of a machined surface, is superimposed on a reference angular velocity 2ω of the tool. The angular velocity of the tool axis increases with increasing proximity to the machined surface center, and reaches maximum at the machined surface center. Adjusting the adjustment parameter a of the oscillation component a sin(Mωt) makes it possible to adjust the flatness of the machined surface.
