Abstract:
The use of engineering materials has increased to a great extent in industries. So it is required to find the optimum parameters in order to have easy and economical machining. Turning operation is most important in the machining process. Especially of hard materials it is difficult sometimes to do so. For better results, the selection of proper process parameters is very important. This dissertation work presents, the effect of process parameters on various materials while performing turning operation and been validated by various methodology techniques. It also highlights on the effect of input controllable parameters over the required output values. According to ISO 3685 design of experiment was carried out. Tool life was calculated according to different cutting speed and machining time keeping feed rate and depth of cut constant. Optimum values were obtained and the effect of cutting speed on tool life was studied.
