Information processing device, machining system, machine tool, and program

A machine tool comprising:

• an attachment unit to which an imaging unit is attachable, the attachment unit being movable to image an image of a workpiece positioned in the machine tool;
• and
• a computation unit for detecting an edge of the workpiece from a two-dimensional image obtained from the imaging unit, and calculating a length of the workpiece from a plurality of edges detected.

A program to process a two-dimensional image generated by being imaged by an imaging unit in a machine tool including an attachment unit to which the imaging unit or a tool is attachable, the attachment unit moving to image an image of a workpiece placed in the machine tool, the imaging unit imaging the image of the workpiece at an imaging position, the program comprising:

• (i) a function of calculating a position of the workpiece based on an image that is imaged after the imaging unit has moved to a predetermined position based on machine coordinates of the machine tool;
• and
• (ii) a function of detecting an edge of the workpiece from the two-dimensional image that is imaged by the imaging unit at an imaging position after the imaging unit has been moved from the predetermined position to the imaging position, and calculating a length of the workpiece from a plurality of edges detected.
