Title:
PROCESSING MACHINE AND PRODUCTION METHOD FOR OBJECT SUBJECT TO PROCESSING
Document Type and Number:
WIPO Patent Application WO/2023/085116
Kind Code:
A1
Abstract:
In a processing machine 1, a Z-axis electric motor 39 moves a main shaft 37 in the Z direction. A Z-axis position sensor 69 detects the position of the main shaft 37 in the Z direction. A rotation sensor 71 detects rotation of the main shaft 37. When a workpiece 103 is processed by a tool 101 in a state where the main shaft 37 is rotating, a control unit 5 controls the Z-axis electric motor 39 on the basis of a detection value of the Z-axis position sensor 69 so as to move the main shaft 37 to a relative position set with respect to a predetermined reference position in the Z direction. The control unit 5 acquires, as the reference position, a position detected by the Z-axis position sensor 69 when a prescribed signal is input in a state where rotation of the main shaft 37 is detected by the rotation sensor 71, the main shaft 37 is moved in the Z direction, and the tool 101 and a reference material come into contact with each other in the Z direction.
