Abstract
Stability is a factor that largely determines the efficiency of the grinding process. Process
stability is characterized by high output parameters during the whole period of work. Increasing the
process stability is of particular importance in developing flexible computer-aided manufacturing
under unmanned operation conditions. Because of homogeneity and normal distribution violation,
research was conducted by the non-parametric statistical method that improved the accuracy of
forecasting measures of dispersion. It was found that a more stable process was predicted in terms
of all indicators and parameters for grinding the high-speed plate Р12Ф3К10М3 at the sparking-out
stage. The highest stability of the microroughness formation process by the criterion of a quartile
width was determined in grinding the high-speed plate Р9M4K8 of four double passes and in
grinding the high speed plate Р12Ф3К10М3 of three double passes.
