Abstract

Machining of bulk Ti6Al4V is relatively difficult owing to low elastic modulus, high work hardening tendency, stickiness, poor thermal conductivity besides formation of long continuous chips during machining. Near net shaping through green machining could be a viable alternative to conventional milling procedure. Herein, fabrication of Ti6Al4V dental root and spinal plate equivalents was successfully demonstrated through machining of green Ti6Al4V compacts prepared by plastic dough processing. For process reliability, the green as well as the sintered components were characterized for physico-mechanical properties, defect and shrinkage analysis for dimensional accuracy of the desired objects and Weibull modulus study for ensuring reliability of mechanical properties of the samples. Evidently, green machining could be a simple viable alternative for manufacturing of titanium implants in a cost-effective way.
