Research the quality of the caprolon turning with ceramic cutting tools

Abstract

The aim of this study is the comparative analysis of caprolon turning with replaceable polyhedral plates made from different materials namely one plate made from wolfram and cobalt alloy VC8 another from ceramic material tungsten free carbide KNT16. The basis of the experimental setup is laboratory research stand STD.201-2 which is used to study the technological system dynamics and the cutting forces registration at turning. The stand functionally consists of the head-tool holder, the interface unit, the sensors connecting module and PC. It is experimentally proved that caprolon turning both with the VC8 alloy cutting plate and the plate made from ceramic material KNT16 is a stable process. This is evidenced by the slight changes values of cutting force main component wherein the range of changes in the case of turning with the ceramic plate is smaller in comparison with the turning option with wolfram and cobalt alloy plate for the selected processing mode.
