Abstract
A controller of a machining device includes an X correction value determiner to determine an X correction value based on an X coordinate value obtained when a detection tool clamped by a clamp is brought into contact with a predetermined X reference point, a Y correction value determiner to determine a Y correction value based on a Y coordinate value obtained when the detection tool clamped by the clamp is brought into contact with a predetermined Y reference point, an actual length determiner to determine an actual length of the detection tool clamped by the clamp, and a Z correction value determiner to determine a Z correction value based on the X correction value, the Y correction value, the actual length of the detection tool, and the design length of the detection tool.
