This paper reports ductile or partial ductile mode machining of silicon, glass and some advanced ceramics. Results are presented using scanning electron micrographs of the machined surfaces. Grinding and lapping operations using inexpensive machine tools could produce ductile streaks on surfaces of these brittle materials under good conditions. Manufacture of spherical glass lenses by the fract...

Vibratory treatment is widely used in various industries for performing finishing technological operations, e.g., lapping, polishing, glazing, strengthening (hardening), etc. The problems of maximizing the accuracy and performance vibratory equipment provide necessity optimizing motion trajectory (path) corresponding working member. main purpose these investigations to substantiate possibilitie...
