CONTROL DEVICE FOR MACHINE TOOL AND MACHINE TOOL

摘要

A control device for a machine tool for machining a workpiece while orbital movement is performed for causing an auto-rotating rotary tool to move in a circular manner, the control device comprising: a reading and interpreting unit for reading a machining program containing input information; and a computing unit for combining a first tool pathway along which a rotary tool travels and which has been set on the basis of input information about the travel of the rotary tool, and a second tool pathway along which the rotary tool orbits and which has been set on the basis of input information about the orbital movement, and for setting a third tool pathway along which the rotary tool travels in a machining shape while moving in an orbital manner.

主权项

1. A control device of a machine tool which makes a rotary tool rotate and makes the rotating rotary tool circulate relative to the workpiece for revolution motion while advancing so as to machine a workpiece, comprising:
a reading and interpreting part which reads a machining program in which input information of advance of the rotary tool which advances along the machining shape of the workpiece and input information of revolution of the rotary tool are separately input; and an operating part which combines a first tool path of advance of the rotary tool which is set based on the input information of the advance of the rotary tool and a second tool path of revolution of the rotary tool which is set based on the input information of the revolution of the rotary tool to set a third tool path of advance of the rotary tool along the machining shape while revolving.
