Experimental Investigation of Surface Roughness in Turning Operation of 16MNCR5

Machining operations are involv3ed in many manufacturing industries. Turning process is one of the most fundamental cutting processes. Cutting used in metal cutting. Surface finish and dimensional tolerances are used to determine quality of product and are the important quality attributes of turned product. In the present paper of investigation the experimental work has been employed for the optimization of input parameters for the improvement of quality of the product of the turning operation on CNC lathe. The input process parameters taken are feed rate, depth of cut and spindle speed and the surface roughness is taken as the output response parameters in the present investigation Taguchi’s L9 has been used in design of experiment for optimization of input parameters in present investigation. This paper accessed to introduce and thus verifies experimentally to introduce and thus verifies experimentally to has now the Taguchi’ parameters design could be used to identify the valuable processes parameters and optimize the surface roughness. In turning operation. The present work shows that spindle speed is the main factor for minimizing the surface roughness factor for minimizing the surface roughness.
