Abstract

Efficient grinding of high performance metal matrix composites requires selecting operating parameters to obtain improved surface finish while keeping the energy spent at optimal level. Lowering grinding costs in industrial application is constrained mainly by large amount of specific energy consumption and surface damage to the metal matrix composites which leads to surface quality degradation. Hence in this paper attempts are made to minimise the specific energy during surface grinding of Al6061-SiC35p composite materials. DRAC’s with three different SiC volume percentage, table feed and depth of cut during grinding are considered as process variables. Taguchi L27 design array is used to identify the influence of various grinding process variables on the process parameters. The design of grinding factors is based on response surface methodology. Central composite design has been employed to develop a second-order model for specific energy. The final goal of experimental study focuses on determination of optimum surface grinding operating conditions for minimization of surface roughness and specific energy. The response surface model developed in this study is shown to perform very well in capturing the non-linear relationship between the grinding variables and process parameters
