Method of Lathe Tool Condition Monitoring Based on the Phasechronometric Approach

Abstract

This paper presents the results of a correlation study of cutting tool deterioration and the measurement results of a phase chronometric system. The significance of this work is because a tool failure can be a reason for defects and even for the failures of machine components. Phase-chronometric approach has been implemented and showed good results in such complex technical objects as turbines and hydraulic units and is considered as a possible alternative or complement to existing methods of the tool condition diagnostics. We provide a brief description of the phase-chronometric method, its advantages and theoretical basis, as well as the main components and operating principle of the phase-chronometric system. The paper describes how to obtain experimental measurement data, its mathematical processing and the data that supports the possibility of studying the cutting process by the phase-chronometric method, as well as the obtained experimental results correlated with the lathe tool deterioration in the determined cutting process conditions.
