Abstract
A method of determining the breakage of a tool in a machine tool is disclosed. The method automatically senses a physical characteristic of the operation of the machine during a cutting operation. Then, if the sensed value indicates a potential break in the cutting edge of the tool, an electro-optical sensor used to examine the shape of the tool and to automatically determine whether the tool shape is also indicative of tool breakage.
Claims9
A method for determining tool breakage in a machine tool comprising the steps of:
- providing an electro-optical sensor in said machine tool capable of automatically determining a shape of the cutting edge of said tool,
- automatically sensing a physical characteristic of an operation of said machine tool during cutting with said cutting edge,
- automatically determining that the sensed value of the operation of the machine tool has provided information indicative of a potential break of the cutting edge of said tool,
- automatically examining the shape of said tool with said electro-optical sensor when information indicative of a potential break has been sensed, and
- automatically determining if said shape is also indicative of tool breakage.
