Theoretical determination of technological inheritance of quality parameters of superficial layer for parts under mechanical treatment

摘要

Theoretical formulae for calculating the parameters of roughness, waveness and hardening degree, taking into account the initial quality of the superficial layer for the cutting and hardening treatment, are given. The created program and results of its execution allowed to determine the level of influence of the initial quality parameters of the parts superficial layer on parameters being formed during the treatment. The data analysis has shown the complicated nature of the technological inheritance of the superficial layer quality parametrs and its change depending on treatment conditions within a wide range from 2,9 % to 81,8 %.
