Analysis of Wear Cutting Tools by Complex Powere-xponential Function for Finishing Turning of the Hardened Steel 20CRMO5 by Mixed Ceramic Tools

Abstract

In this paper it is analised the dependence regression between flank wear tools or wear out of belt width on the back surface VB and cutting time t in the form of complex power-exponential regression equation for turning of steel grade 20CrMo5 of cutting tools from mixed ceramic for the different values of the cutting speed v=79.2 and 113.1 m/min. Correlation coefficient for given examples of experimental researching is R=0.993 and it means that relative error of experiment is less than relα =3.7 %.
