摘要：

The present work is undertaken to investigate and characterize the machining characteristics (such as metal removal rate, etc) of uni-axially pressed titanium sintered powder metallurgy components. Powder is uni-axially pressed at designated pressure of 840 MPa to form cylindrical samples and the green compacts are sintered at 0.001 mbar for about 4 h with sintering temperature varying from 1350 degrees C to 1450 degrees C. Machining experiments are conducted at different parameters in a CNC operated wire-cut EDM. The metal removal rate (MRR) of the machined surface was measured critically. The influence of pulse-on time, pulse-off time and sintering temperature on the MRR of the sintered preforms has been investigated thoroughly. The maximum MRR was achieved at 10 mu s of pulse-on time, 11 mu s of pulse-off time and sintering temperature of 1450 degrees C.
