Abstract

A machining apparatus including a distributor which generates a movement command for a motor; a position detector which detects a working position of the motor; and a motor controller which controls a corresponding motor based on the movement command, with the output of the position detector being fedback to the motor controller. During a scanning measurement control, in place of a machining tool, a probe sensor capable of measuring a distance relative to a work is attached, and while input of the movement command to the motor controller is interrupted, a measurement result obtained by the probe sensor is fedback to the motor controller. The detection result obtained by the position detector is superimposed on the measurement result and outputted as information on a shape of the work.

Dependent claims

A machining apparatus comprising:

a distributor configured to generate a movement command for a motor;
a position detector configured to detect a working position of the motor;
and
a motor controller configured to control a corresponding motor based on the movement command, with a detection result obtained by the position detector being fedback to the motor controller in order that the detection result obtained by the position detector corresponds to a predetermined working position;
wherein:
during a scanning measurement control, in place of a machining tool, a probe sensor capable of measuring a distance relative to a work is attached;
during the scanning measurement control, input of the movement command to the motor controller is interrupted, and a measurement result obtained by the probe sensor is fedback to the motor controller in order that the measurement result obtained by the probe sensor corresponds to a predetermined distance;
and
during the scanning measurement control, information In which the detection result obtained by the position detector and the measurement result obtained by the probe sensor are superimposed on each other, is outputted as information on a shape of the work.
