Title:
CONTROL DEVICE FOR MACHINE TOOL, AND MACHINE TOOL PROVIDED WITH SAID CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/146945
Kind Code:
A1
Abstract:
 The present invention provides a machine tool making it possible to: feed a cutting tool in the machining direction, on the basis of conditions set by a user, while causing the tool to vibrate in a reciprocating manner along the machining direction; and cut a workpiece smoothly while segmenting the chips. The present invention also provides a control device for the machine tool. A machine tool (100) provided with setting means (C1, C2) and a correcting means (C1), whereby the value of a parameter set by the setting means (C1, C2) is corrected by the correcting means (C1), and a workpiece (W) is machined; and a device (C) for controlling the machine tool (100). The setting means (C1, C2) set the value of at least one parameter, the parameters being the number of relative rotations when the workpiece is machined, the number of reciprocating vibrations per relative rotation, and the vibration frequency that results from the period over which an operation command can be issued by the control device (C). The correcting means (C1) sets the unset parameter(s) to a prescribed value and, on the basis of the value(s) of the parameter(s), corrects the value(s) of the parameter(s) set by the setting means (C1, C2).
