Abstract

A dependence describing the influence of the longitudinal feed and radius at the tool tip on the arithmetic average de-viation of the roughness of the profile Ra during the rotation of the AK8 alloy is obtained. Statistical analysis of the obtained model using the Cochran, Student and Fisher criteria showed the suitability of the obtained model with a 95% probability of predicting the results of the experiment.
