CNC turning is one of the most important and widely used manufacturing processes in engineering industries. Today’s manufacturing scenario, optimization of metal cutting process is essential for a manufacturing unit to respond effectively to competitiveness and increasing demand of quality which has to be achieved at minimal cost. Surface finish is one of the prime requirements of customers for CNC machined parts. The purpose of this project is primarily focused on the analysis of optimum cutting conditions to get good surface finish. This project presents an experimental study to investigate the effects of cutting parameters like Cutting speed, feed and depth of cut and cutting oil used on surface finish on Aluminium metal for contour turning and turning processes. The PATIL ENTERPRISES is an ISO 9001-2000 certified company established in 1985 with concentration in Manufacturing & Machining job works. Units expanding its manufacturing range to a wide variety of Gears, Pinions, Shafts and Valve Equipment’s such as Ball, Stem for Ball Valve, Pinion for Actuator and Gate for Gate Valve. There are some problem related to surface finish of CNC turning components, OVAT Analysis is used for investigation of various CNC parameters which affects on surface Finish of components & CNC Programming modification according to required surface finish value.
