Control device for machining apparatus, machining apparatus, and correction method of machining data

A control device for a machining apparatus including a multi-joint arm provided

• with a machining tool for machining a machining object, the control device comprising:
• a storage section that stores machining data indicating a machining region of the machining object by the machining apparatus;
• a distance measurement sensor placed on the arm and that measures a distance between the machining object and the machining apparatus for each machining surface of the machining object;
• and
• a correction section that corrects the machining data for each of the machining surfaces based on a measurement result by the distance measurement sensor, wherein
• the machining data is divided by the machining surfaces, for equalizing the machining surfaces and reference surfaces, and is stored in the storage section;
• and
• the correction section corrects the machining data divided by the machining surfaces, based on the measurement result by the distance measurement sensor.

A correction method of machining data indicating a machining region of a machining object by use of a machining apparatus including a multi-joint arm provided with a machining tool, the method comprising:

• a first step of measuring a distance between the machining object and the machining apparatus for each machining surface of the machining object with a distance measurement sensor placed on the arm;
• and
• a second step of correcting the machining data for each of the machining surfaces based on a measurement result by the distance measurement sensor, wherein
• the machining data is divided by the machining surfaces, for equalizing the machining surfaces and reference surfaces, and is stored in a storage section;
• and
• the second step corrects the machining data divided by the machining surfaces, based on the measurement result by the distant measurement sensor.
