Experimental Complex for Assessing the Effect of Wear on the Temperature and Vibration of the Tool when Turning Metals

Abstract

The work is devoted to the development of an experimental measuring complex designed for conducting experiments to assess the mutual influence of tool wear, temperature during cutting and vibration activity of the tool when turning metals on metal-cutting machines. In this paper, it is proposed to place three vibration transducer sensors on the tool holder itself, as well as to insert an artificial thermocouple inside the cutting plate. The introduction of the thermocouple is made in such a way that temperature measurements are made close to the back surface of the tool formed during cutting. The conducted studies have shown the high efficiency of the measuring system and the possibility of its use for the identification of mathematical models of the cutting system. Research methods full-scale and numerical experiments in which the Matlab package of mathematical programs was used for data processing and analysis. Results and discussion. The results of full-scale and numerical experiments are presented, in particular, graphs of coordinate changes describing tool deformation, and data sets are obtained that reflect the dependence of the vibrational energy of tool movements on the reaction time of the thermodynamic subsystem of the cutting system.
