Abstract
A machine tool includes a camera fixed to a predetermined imaging area and for imaging a tool inserted into the imaging area, a tool holding portion to which a tool is attachable, and a machining control portion for controlling the tool holding portion in accordance with a machining program and machining a workpiece with the tool. The machining control portion moves the tool toward the imaging area after rotating the tool to image the tool.
Claims8
A machine tool comprising:
- a camera fixed to be capable of imaging a predetermined imaging area and for imaging a tool located in the imaging area;
- a tool holding portion to which a tool is attachable;
- a machining controller controlling the tool holding portion in accordance with a machining program and machining a workpiece with the tool;
- and
- a cover controller closing a shutter located between the imaging area and a predetermined tool standby position during rotation of the tool, and opening the shutter after an end of the rotation of the tool,
- wherein the machining controller and the cover controller include a processor and a memory,
- wherein the machining controller moves the tool toward the imaging area to image the tool after rotating the tool, and
- the machining controller moves the tool holding portion toward the predetermined tool standby position different from an imaging position where a tool is positioned when the tool is to be imaged, rotates the tool at a speed equal to or higher than a predetermined rotation speed at the predetermined tool standby position, and subsequently moves the tool toward the imaging area to image the tool,
- wherein the machining controller moves the tool toward the imaging area after the shutter is opened.
