Title:

COPY CAM DRIVING DEVICE FOR MACHINE TOOL

Document Type and Number:

WIPO Patent Application WO/1982/002016

Kind Code:

A1

Abstract:

An apparatus for imparting a predetermined motion to an object with a cam, in which a load compensating unit (17) is disposed at an arbitrary position of a driven section for applying force or torque therefrom to the driven section so as to cancel variations of the contacting force between a cam (10) and a cam follower (11) induced by the variation or the like of the inertial force caused by the motions of the driven sections (8, 16) or of the load applied to an operating point, thereby maintaining a constant contacting force and enabling the performance of stable and accurate motion of the cam driving system even during high speed operation. Particularly, high working accuracy at high speed can be carried out, such as machining a lead of a VTR lower cylinder by using an end face cam.
