Energy Criterion for Metal Machining Methods

The optimization criteria of manufacturing processes are reviewed. Actual technical, economic and energy criteria used in mechanical engineering technology are analyzed. New energy criterion “action of technological system” is introduced. The proposed criterion is defined as the work of shaping, done over the certain time interval. Investigated criterion is developed for evaluation and selection of technological processes by energy parameters. Mathematic simulation of external turning has been carried out. Analytic relations between the criterion “action of technological system” and cutting parameters have been determined. It has been theoretically established that cutting speed and line feed have the most influence on the investigated criterion. Experimental research of proposed criterion for rough turning and finish turning of external cylindrical surface has been carried out. Empirical relations between the investigated criterion and cutting parameters are determined based on experimental data. Analysis of experimental data for rough turning and finish turning of external cylindrical surface has been provided. Theoretical and experimental data are compared. According to the results, it was proved that line feed and cutting speed have the most influence on the criterion “action of technological system”.
