Probability-Statistical Estimation Method of Feed Influence on As-Turned Finish of Steels and Non-Ferrous Metals

摘要

Based on the experimental data on the roughness parameter R a , which stands for the mean arithmetic deviation of the profile, as obtained in the process of turning test specimens from different materials with constant elements of the cutting mode (depth a and velocity v ) and structural-geometric parameters of the cutting tool, but with different feed rates f , the probability-statistical method for estimating the influence of feed rate f on the resulting surface roughness by the parameter R a is proposed using the theory of a small sample.
