Abstract
A machine tool includes: an imaging unit for capturing an image of a tool from a side of the tool; a shape extraction unit for extracting the shape of the tool from the image of the tool captured by the imaging unit; a wear detection unit for detecting the degree of wear of the tool based on the shape of the tool; and a changing unit for changing at least one of the pitch and the depth of cut according to the degree of wear.
Claims11
A machine tool that performs a hale machining for cutting a workpiece along a cutting direction at a specified depth of a cut and at intervals of a specified pitch using a hale tool, the machine tool comprising:
- a tool support and the hale tool, the hale tool being mounted to the tool support during cutting of the workpiece;
- an image capturer configured to capture an image of the hale tool from a side of the hale tool;
- and
- a signal processor configured to:
- extract a shape of the hale tool from the image of the hale tool that was captured by the image capturer;
- detect a degree of wear of the hale tool based on the extracted shape of the hale tool;
- detect whether there is a chip at a tip of the hale tool based on the extracted shape of the hale tool;
- detect a degree of abrasion of the tip of the hale tool as the degree of wear of the hale tool when there is no chip at the tip of the hale tool, and increase the depth of cut as the degree of abrasion increases;
- and
- detect a degree of chipping as the degree of wear of the tool when there is a chip at the tip of the hale tool, and decrease the pitch as the degree of chipping increases.
