Influence of machining parameters on surface roughness and material removal rate in machining carbon fiber reinforced polymer material

Machining of polymeric materials has become increasingly important in any engineering industry subsequently the prediction of surface roughness then the material removal rate. Surface quality has greater influence on components which are coming in contact with each other. So it becomes necessary for measuring and studying machined surfaces and its behavior. In this experimental study, turning operation was carried out using carbide cutting tool on a carbon fiber reinforced polyester resin to measure its surface roughness. Combination of machining parameters that offer the good surface finish was found out using, and then the highly influential machining parameter that affects the surface characteristics also was found out using ANOVA analysis. A fuzzy rule based model was developed to predict surface roughness of parts which are made by turning operation. It was observed that there exists a good correlation between the surface roughnesses obtained from experimental as well as fuzzy rule based prediction. This experimental study also presents the influence of machining parameters on material removal rate.
