Determination of microrelief parameters of spherical parts processed by centerless grinding

In the processing treatment of cleanoff and finishing operations of the parts with abrasive tools, very important tasks are both predicting their results depending on the assigned modes, and the appointment of modes depending on the required quality of the processed surfaces. In the article, the parameters of the microrelief formed as a result of centerless grinding of a complete sphere are determined analytically. The influence of the aging process on the formation of spherical surface roughness is determined. Calculations of the arithmetic mean deviation of the micro-profile of a spherical surface are given, depending on the number of working strokes of the grinding wheel.
