Measuring arrangement for detecting the actual position and the topography of a rotating grinding wheel

摘要

The invention relates to a measuring arrangement for detecting the actual position and the topography of a rotating grinding wheel. The invention relates to grinding machines for producing toothed wheels with a high quality tooth system. The object of the invention is to reduce disturbing influences in the detection of measured values, in order to determine and reproduce the actual position and topography of a rotating grinding wheel with high accuracy. In the solution according to the invention, this is achieved when deformable piezotransducers (14) are provided with base or side diamond probes (15; 16) which scan the grinding wheel (1) and are arranged in a thermally neutral zone (S). A signal proportional to the deformation of the piezotransducer is fed via arithmetic units (18; 24; 26) to the positioning drives (7; 20; 22) of a grinding-wheel dresser, a grinding wheel or an NC work positioning unit. <IMAGE>
