Device for online measurement of wear on tools during machining of abrasive materials, uses a source of light to illuminate rotary cutters and an optical sensor to detect reflection from the wear surfaces of a cutter

摘要

Rotary cutters (2) are illuminated by a source of light. An optical sensor (3) detects reflection from the wear surfaces of a cutter. A computer evaluates the signal that is generated and information is detected about the level of wear on the cutters.
