Аннотация
A study of the ultrasonic dimensional processing of KU-1-grade quartz glass, SO-115-grade glass ceramics, tungsten carbide, and KP-1-grade alumina ceramics at different amplitudes and frequencies of the ultrasound effect has been carried out. The dependence of the value of defects (cleavages) on the amplitude-frequency characteristics of the ultrasound and the structural features of the material being processed has been determined. It has been determined that, by applying certain oscillation frequencies of the tool during processing at lower amplitudes, one can reduce the sizes of cracks (cleavages) and the magnitude of roughness while preserving the process performance. It has been shown that the hardening of working surface of the tool based on the exposure of low-temperature plasma of combined discharge makes it possible to increase its age resistance by up to three times.
