The present study aims at finding the residual stresses on aluminum hybrid composites during turning operation. The composites with varying percentage by weight reinforcement of 2, 4, 6 and 8 RHA and SiC in equal proportions were fabricated using two stage stir casting process. X-ray diffraction was used to study the residual stresses on the surface layer of the machined surface. It was observed that the residual stresses generated during casting were considerably larger when compared to the stresses generated during machining of composites. It was also noticed that the residual stresses were found to decrease with the increase in the reinforcement and increases with the increase in cutting speed. The related mechanisms are explained and presented in this work. |
