Determination of the relative position between grinding wheel and a cylindrical workpiece on a 7 axis grinding machine by acoustic emission

Abstract

The contact between grinding wheel and workpiece in the grinding process is recognized by acoustic emission (AE)

A Quick-Test Method to Determine the Grinding Wheel Topography Based on Acoustic Emission

“…The position associated to the first contact between grinding wheel and diamond tip is stored on the grinding machine´s numerical control and used as a reference position for the mapping procedure. It was possible to recognize the first contact with interferences smaller than 1µm (Boaron 2009), allowing to carry out the mapping procedure in the elastic deformation range. The use of such automatic contact recognition strategy has presented itself as a novelty in relation to the previous published mapping procedures.…”

“…The use of such automatic contact recognition strategy has presented itself as a novelty in relation to the previous published mapping procedures. The same contact recognition strategy has been successfully used as the basis for an industrial application in the manufacturing of broaching tools (Weingärtner and Boaron, 2011), (Weingärtner and Boaron, 2009).…”
