This paper deals with the development of a software package which assists an automatic feature recognition technique to extract the geometrical features from the subsequent Standard for the Exchange of Product model Data (STEP) file which is generated using the 3D CAD model. The following aftermath is a crucial facet in downstream applications like- generation of process plans, part programs etc. A generalized Java code has been formulated to recognize the turning features of the previously extracted information regarding the rotating parts from the STEP file and henceforth this information is employed  to effectuate a Computer Numerical Control (CNC) part programs using several logics. Furthermore, with the aid of a statistical technique called Response Surface Methodology (RSM), we optimize the acquired response and using the best combination of surface roughness and machining time, we generate the process plan. The authors present an example to demonstrate the application of the proposed methodology using CNC simulation software and its subsequent validation.
