Turning process is the most common process which is used in manufacturing industries. Turning process is influenced by many factors such as cutting speed, feed and depth of cut. In machining operations, surface quality of the product is given most importance. The fact is that, surface quality is highly influenced by process parameters. However, the process parameters are different for different responses. In this paper the effect of nose radius and machining parameters including cutting speed, feed and cutting fluids on surface roughness in a turning operation are investigated by using the Taguchi optimization method.
