RESEARCH OF THE WEAR OF THE CUTTING EDGE OF DIAMOND CUTTING WHEEL WHEN CUTTINGPIEZOCERAMICS
The necessity of studying the wear of diamond grains and the cutting edge of a diamond cutting wheel when cutting piezoelectric ceramics at various cutting conditions is substantiated in order to increase productivity without reducing the quality of cutting.The photographs of fragments of the most characteristic sections of the cutting edge of a diamond cutting wheel before and after cutting piezoceramics are given.Based on the results of a comparative analysis of the obtained data on the wear of diamond grains and the state of the cutting edge, it is shown that it is possible to select the optimal cutting modes for piezoceramics with sufficient control of the cutting process.Despite the apparent simplicity of determining the optimal cutting conditions for piezoelectric ceramics, there are certain problems associated with the peculiarity of the physicochemical properties of piezoceramics, in particular, fragility and changes in physical properties during cutting due to increased temperature and mechanical stresses, which are eliminated by adjusting cutting conditions, which are solved at the present level. through active control of the cutting process.
