Development of an Empirical Model for Optimization of Machining Parameters to Minimize Power Consumption

摘要

The manufacturing sector consumes huge energy demand and the machine tools used in this sector have very less energy efficiency.Selection of the optimum machining parameters for machine tools is significant for energy saving and for reduction of environmental emission.In this work an empirical model is developed to minimize the power consumption using response surface methodology.The experiments are performed on a lathe machine tool during the turning of AISI 6061 Aluminum with coated tungsten inserts.The relationship between the power consumption and machining parameters is adequately modeled.This model is used for formulation of minimum power consumption criterion as a function of optimal machining parameters using desirability function approach.The influence of machining parameters on the energy consumption has been found using the analysis of variance.The validation of the developed empirical model is proved using the confirmation experiments.The results indicate that the developed model is effective and has potential to be adopted by the industry for minimum power consumption of machine tools.
