Mechatronic means for machine accuracy improvement

Abstract

The paper deals with the mechatronic means for the accuracy improvement of metal cutting machines, co-ordinate measuring machines, robots, etc. The mechatronic correction means of raster scales, encoders errors and final 3-D position correction of a cutting instrument or touch probe are presented. The technical solutions are given with the application of active materials for smart probes and piezoactuators. A case of calculations for piezoactive raster plates is described together with volumetric control diagrams and the examples of practical implementation.
