Document Type and Number:
WIPO Patent Application WO/2023/136138
Kind Code:
A1
Abstract:
Provided is a technique for detecting an excessively large tool that cannot pass through a passage port. This machine tool has a machining area and a tool accommodation area that is partitioned from the machining area by a partition. The partition has a passage port formed therein. The machine tool is provided with: a camera which is so disposed as to capture an image of a tool passing through the passage port; a rotary drive unit which rotationally drives a spindle; a position drive unit which moves the position of the spindle; and a control unit for controlling the machine tool. The control unit executes: a process for, prior to accommodating a tool in the tool accommodation area, controlling the position drive unit so as to bring the spindle to a predetermined position within the machining area and controlling the rotary drive unit to cause the axial direction of the spindle to be oriented toward a predetermined direction; a process for determining, on the basis of an image obtained from the camera, whether or not the tool can pass through the passage port; and a process for implementing predetermined anomaly countermeasure processing on the basis of a determination that it is impossible for the tool to pass through the passage port.
