Reliability of centrifugal–rotational finishing by steel shot

Surface quality assurance and process reliability in the processing with a ball-rod hardener

“…It is necessary to develop a set of adequate theoretical models describing the surface quality development during processing. Nowadays, the following relations have been identified [1][2][3][4][5][6][7][8][9]. They allow to define: -surface roughness:…”

“…The study of reliability parameters in the ball-rod hardener processing is an important aspect of the successful technological process design, which contributes to the specified quality of products. For reliability analysis, according to [4][5][6], reliability coefficients are used according to Russian Standard GOST 27.202-83. When controlling technological processes on a quantitative basis, using the relations presented in the Russian Standard, the values of accuracy indicators for the controlled parameter are determined: the accuracy ( ) should be greater than zero.…”

“…The ballrod hardener is a universal device that allows to process both flat surfaces and surfaces of irregular form, including those with a small difference in height. The ball-rod hardener device was invented at the Technology of Mechanical Engineering Department of DSTU under the guidance of Professor A. P. Babichev [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15].…”

The dependence of the performance of the process of finishing vibration processing on the shape of the abrasive tool (granules)

“…However, it was established in [10] that 75% of all impacts on the treated surface during vibrational treatment are oblique, and, consequently, the point contact becomes linear and the linear contact becomes plane contact.…”
