Title:
POSITIONAL RELATIONSHIP MEASURING DEVICE, CONTACT DETECTION METHOD, AND PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/162927
Kind Code:
A1
Abstract:
In the present invention, a control device: causes a dummy tool to move relative to a reference block so that the reference block and the dummy tool come into contact (S20); and acquires a first coordinate value of a reference point when the reference block and the dummy tool come into contact (S22). The control device: rotates a main shaft 180 degrees around a center axis (S24), and then causes the dummy tool to move relative to the reference block so that the reference block and the dummy tool come into contact (S26); and acquires a second coordinate value of the reference point when the reference block and the dummy tool come into contact (S28). The control device derives the relative positional relationship between the center axis and the reference block from the first coordinate value and the second coordinate value.
