Combined machining apparatus, method for controlling the combined machining apparatus, and program for performing the method

A method carried out by a machine control unit of a combined machining apparatus to perform cutting and friction stir welding, the method comprising:

• reading a command from a machining program to be executed by the combined machining apparatus, the command indicating a working tool to be called by the machining program;
• determining whether the working tool is a cutting tool or a friction stir welding tool, based on the command;
• upon determination that the working tool is the cutting tool, allowing correction of a position of the working tool in the cutting, based on a temperature detected by a temperature sensor provided in the combined machining apparatus;
• and
• upon determination that the working tool is the friction stir welding tool, allowing the correction of the position of the working tool based on a load applied to a motor that rotates the working tool in the friction stir welding.

A computer readable storage medium storing a program for causing a machine control unit of the combined machining apparatus to execute processes comprising:

• reading a command from a machining program to be executed by the combined machining apparatus, the command indicating a working tool to be called by the machining program;
• determining whether the working tool is a cutting tool or a friction stir welding tool, based on the command;
• upon determination that the working tool is the cutting tool, allowing correction of a position of the working tool in the cutting, based on a temperature detected by a temperature sensor provided in the combined machining apparatus;
• and
• upon determination that the working tool is the friction stir welding tool, allowing the correction of the position of the working tool based on a load applied to a motor that rotates the working tool in the friction stir welding.
