Abstract
In a controller where a contour machining is performed through a synchronous control between a mechanically movable portion (servo axis) driven by a servo motor and a main shaft (spindle axis) driven by a spindle motor, the position of the servo axis and the position of the spindle axis are collected at the same timing for each predetermined cycle and are stored. The position data of the servo axis and the spindle axis stored are converted to obtain a machining contour shape data, and the shape obtained is displayed on a display device of a personal computer or the like.
Claims6
A controller which synchronously controls a servo axis driven by a servo motor and a spindle axis driven by a spindle motor to machine a predetermined contour shape, comprising:
- collecting means which collects the position data of the servo axis and the position data of the spindle axis at the same timing for each predetermined cycle;
- storing means which stores the position data of the servo axis and the spindle axis collected by the collecting means;
- converting means which converts the position data of the servo axis and the spindle axis to obtain a machining shape data;
- and
- means which outputs the machining shape data obtained by the converting means.
