Cutting Tool Reliability Testing and Data Proceeding

Abstract: The present paper underlines the necessity of the cutting tools producers warranty about tools reliability and propose also the ways of estimation for such of indicators. In the paper is also proposed to complete the existing standards with requirements about the reliability testing conditions and the methods of testing data proceeding are presented. Also in the paper the Weibull’s model adequacy for a large range of machining conditions of HSS cutters is demonstrated. There is also shown that change of these machining conditions affect the values of ß and ? parameters, as well as the range of TBF. For these reasons, in order to estimate some realistic reliability indicators, one have to establish proper conditions for reliability tests of cutting tools, especially for HSS cutters.
