Setting method of machine tool, computer, machine tool, machine tool system, computer program, and computer readable medium

A computer comprising:

• a processor;
• and
• a memory storing instructions that, when executed by the processor, cause the processor to perform operations comprising:
• generating a 3D virtual space that represents a virtual reality environment;
• preparing a first 3D model representing a table of the machine tool;
• preparing a second 3D model representing a workpiece provided on the machine tool;
• preparing a third 3D model representing a fixture to fasten the workpiece to the table;
• preparing a relative position of a program zero with respect to a reference position of the second 3D model, the program zero being used in a machining program to machine the workpiece;
• setting parameters representing positions and orientations of the first to third 3D models, respectively in the 3D virtual space;
• and
• obtaining, based on the relative position of the program zero, the first to third 3D models, and the parameters, a position of a measurement point whose 3D position in a real space is calculatable by contacting with the workpiece, a probe attachable to the machine tool.
