Product quality is very important for the company. This is because, bad quality products will affect the consumer's confidence, image and sales of the company. It may even affect the survival of the company. So, it is very important for every company to make better quality products. Product quality is also very important for consumers. In the manufacturing industry, it is commonly stated that "Quality drives productivity." Improved productivity is a source of greater revenues,employment opportunities and technological advances. In manufacturing industries, manufacturers focus on both the quality and productivity. To increase the productivity, computer numerically control (CNC) machine tools have been implemented during the past decades. Surface roughness is one of the most important parameters to determine the quality of product. The mechanism behind the formation of surface roughness is very dynamic, complicated, and process dependent. Several factors influence the surface roughness obtained in a CNC turning operation. These can be categorized as controllable factors (spindle speed, feed rate and depth of cut) and uncontrollable factors (tool geometry and material properties of both tool and work piece. The aim of present study is to develop surface roughness prediction models using response surface methodology (RSM) based on centre composite rotatable design (CCRD). An attempt has also been to analyse the effect of machining conditions on surface roughness during turning of AISI 316 L stainless steel with carbide insert.
