Влияние ультразвуковых колебаний на величину сил резания в процессе алмазной доводки ювелирных камней

An influence of ultrasound vibrations initiated in a tool on decrease of cutting forces in the process of abrasive machining of jewel specimens has been investigated. The paper contains description of an pilot unit, a tool design and methodology of investigations. Mechanism of contact interaction due to ultrasound vibrations is described in the paper. Quantitative evaluation of decrease in cutting forces acting in the finishing zone and influence of acoustic and technological factors on the rate of decrease in these forces are given and determined in the paper.
