Optimization of cutting parameters using robust design for minimizing energy consumption in turning of AISI 1018 steel with constant material removal rate

The strategies to reduce energy consumption are obtaining emphasis due to the constant increase in electricity prices, and concern of manufacturing companies and clients about the environmental impact that results from activities related to the production of goods. CNC machine tools, including those that perform turning operations, contribute significantly to the energy consumption in the manufacturing sector. The present work outlines an experimental study to optimize cutting parameters during turning of AISI 1018 steel under roughing conditions and constant material removal rate, in order to get the minimum energy consumption of the machine tool. Robust design is employed to analyze the effects of depth of cut, feed rate and cutting speed on the response variable.
