CUTTING ENERGY AND SURFACE TEMPERATURE ANALYSIS IN GAS COMBUSTION HEATING ASSISTED TURNING

Abstract

Developments inthe mechanical engineering industryare accompanied by the development of new solutions in material machining technologies. One of the directions of this development is combining different processes,with regard to obtaining the required machining process performance. The machining performance rating is commonly based on energy consumption analysis, process productivity, and machining efficacy, at the least. In this paper, an analysis of the steel turning process assisted by gas combustion heating was performed.This combined machining process is widely available, on the one hand, but is unstable and causes negative changes in the workpiece surface layer, on the other. The cutting energy was analyzed, as well as the consumption of energy due to the heating of the workpiece. Based on the experimental data, statistical analysis was carried out, and mathematical models of process performance indicators were developed. By using the developed mathematical models, optimization was carried out in order to obtain the appropriate process parameters, which would result in the lowest heat input and the used energy.
