|Abstract:||Machine components with metal powder can be fabricated using cold compaction/sintering and cold or hot iso-static pressing. This paper investigates the machinability in turning of sintered and Hipped Fe-Mo materials. The commonly used measures of machinability such as cutting forces, surface roughness, tool wear, chip shape and chip color are studied. A detailed study of the material properties of Sintered and Hipped parts is presented. The porosity of a material has been found to have an adverse effect on tool life. This can be explained as the effect of micro-shocks and the reduced thermal conductivity due to the presence of pores. Lower surface roughness has been observed while turning porous specimens at higher speed, lower depth and reduced feed rate. It has been shown that perfect (desirable) chip control can be achieved in turning of porous materials with various combinations of cutting parameters.|
