MULTI OBJECTIVE OPTIMIZATION OF CUTTING PARAMETERS IN TURNING OPERATION OF STAINLESS STEEL (SS304) TO REDUCE SURFACE ROUGHNESS AND CUTTING FORCES

Turning is a machining operation in which the cutting tool moves linearly while the work piece rotates to remove material. Turning is one the most important machining operation in industries. The process of turning is influenced by many factors such as the cutting velocity, feed rate, depth of cut, geometry of cutting tool cutting conditions etc. The finished product with desired attributes of size, shape, and surface roughness and cutting forces developed depends on the above input parameters. Forces developed during cutting affect the tool life hence the cost of production. Hence the cutting forces must be reduced in order t o increase the tool life. At the same time the surface roughness of the finished work piece is also very important. So we have to use multi response optimisation so that the cutting forces and surface roughness are reduced.
