Comparison of Theory and Practice in Analytical Expression of Cutting Tools Durability for Potential Use at Manufacturing of Bearings

Abstract:

The problem effective and economical management of the cutting tools is often the factor that manufacturing enterprises do not attach much importance. Any manufacturer of cutting tools states in promotional and marketing materials, and also in many catalogs data about cutting tools, excluding those subject know-how. Among the following data are also recommended cutting conditions and their dependent of durability of the instrument. If the company uses different cutting parameters, knows the durability of knowledge by F.W. Taylor contained in standard ISO 3685, which can be fast deduced, because dependence on cutting speed durability is in double logarithmic in shape of linear graph. What in case that this assertion was demonstrated by Taylor in 1906 was not true Durability of cutting tool would be different in that case, and it would not be possible to calculate or predict. With this knowledge about invalidity of the Taylor formula for new cutting tools pointed to science and practice by Professor Karol Vasilko, who in its publications published research results to indicate this fact. Article follows the research of Professor Vasilko and provides the opportunity to analytically derive the dependence of T-v_c for cutting materials, where Taylor's relation does not apply.
