Application of RSM for optimal response of process parameters on machining of CFRP composites by using AJM

AJM is a process that can remove material from the Brittle and hard work piece efficiently without the help of cutting tool, and by applying the mechanical energy. The metal removal takes place in this process is due to mechanical erosion. The abrasive and air mixture impinges on the work area with high velocity, commonly ranges between 150m/sec to 300m/sec. The process parameters that all are influences the metal removal rate are Air Pressure, NTD, ND, AFR, Time of machining. The type of Abrasive particles commonly used are silicon carbide, aluminium oxide etc. CFRP is the type of composite which is of light in weight and strong generally used in aerospace applications is considered as work material in our experimentation. For finding the optimality of process parameters there are many methods like taguchi, RSM etc. for finding the optimality. In this article the focus is on the RSM optimal response of process parameters on MRR of CFRP composites, and the variation in response with ANOVA.
