Investigation of Power Consumption in the Machining of S960QL Steel by Finite Elements Method

Abstract

Armor steels have good strength and corrosion resistance; however, due to their difficult machinability, high power consumption occurs. High power consumption increases the cost in machinability studies. Therefore, minimizing power consumption is important for sustainable and cleaner production. In order to minimize power consumption during machining, factors such as workpiece material, cutting tool material and geometry, machining conditions and cutting parameters must be compatible with each other. For this reason, power consumption modeling was carried out in the milling of S960QL structural steel material according to the finite elements method, depending on the cutting parameters. In this context, simulation processes were carried out at three levels for each factor: cutting speed, lateral depth, axial depth and feed rate. The most effective parameter in power consumption was the axial deep of cut. There was a 476% change between the highest and lowest power consumption. It is concluded that finite element modeling is feasible in order to determine the effect of processing parameters on power consumption.
