Abstract
A measuring and control method to check the position and/or wear of a knife element supporting a piece being machined in centerless grinders including foreseeing the generation of signals responsive to the position of the workpiece surface close to the supporting knife element and comparing the signals with reference signals depending on the workpiece size and the optimum position of the supporting knife element. The result of the comparison is responsive to the real position and/or wear of the supporting knife element. A device for the method which comprises a gauge for measuring linear dimensions having at least one moving element adapted to cooperate with the surface of the piece being machined. The moving element is associated to position transducer means connected with threshold circuits to control alarm and control circuits, the control and alarm circuits being responsive to the wear and/or position of the supporting knife element.
