Abstract
A system for determining cutting-tool wear which utilizes a sensor for producing an output signal representing the cutting profile of the tool and a data processing system using microprocessor control which is responsive to the sensor for storing information concerning such cutting profile when the tool is initially installed and for comparing updated cutting profile information with the stored initial cutting profile information to provide output information concerning the wear characteristics of the tool. The wear information can be displayed, either visually or audibly, or can be supplied to an external data processor, such as the overall machine tool processor, for use therein. The system includes means for correcting errors which arise because of sensor and tool bit characteristics.
