Optimization of alternate profile component part machining

Abstract

Abstract Process optimization for machining of component parts with the profile alternate by the length has been reviewed here. The review deals with the optimization criteria applied and shows that the optimization of machining modes normally uses a criterion of cost-effectiveness, which is most often used in up-to-date technologies. With reference to specific organizational and economic conditions at companies of the industry, it is shown that power saving may become a priority when standardizing modes of machining. The power consumption pattern for the cutting process is reviewed. A variable energy value is proposed as an optimality criterion, which depends on parameters optimized i.e. – technological energy. Mathematical models are defined for the optimality criterion and limiting parameters that allow reducing energy consumption of the machining process. Calculations carried out according to the proposed methodology have shown that when the machine electric motor power is above 13.5 kW, work in the energy-saving mode becomes economically viable. Energy savings reach 10 %, while the main time increases by an average of 10%, but the reduction in costs associated with a decrease in energy consumption is 4 times higher than the increase in costs due to an increase in the main time.
