Experimental Investigation and Theoretical Modelling of P20 Steel by using CNC End Milling Machining Process

In current scenario the sustainability principles has to be adopted to tackle the challenges facing in the various industrial sectors. As the machining processes consumes natural resources to a great extent, it has become mandatory for manufacturers to go for sustainable management practices. The sustainability in manufacturing processes can be achieved by integrating all small factors and thus achieving sustainable machining conditions. Machining plays a vital role in the industrial economy and it contributes more than 5% to the country's economy. The machining processes have gone through significant changes in the last decades. Competition has increased drastically to gain more profit. Machining processes are been widely used and attempts have been made to minimize the machining cost and the energy consumption. The machining parameters like speed, feed, depth of cut and the coolants used play an important role in machining economy. Main focus in this work is to enhance the surface integrity and the tool life by utilizing least resources and to reduce the energy consumption. P20 steel have wide application in the moulds for plastic injection cavities and tooling. Also, it is used in the die casting of dies for zinc. Thus, the surface roughness plays an important role in the machining of the P20 steel. In this paper, the experiments have carried out on P20 steel on CNC milling process by adopting Taguchi Analysis to optimize surface roughness and tool life. Besides, analysis of cutting forces by using fuzzy logic is studied to evaluate the energy consumption.
