Abstract
A new rapid manufacturing process of metallic parts using green machining has been developed. In this process, metal powder for metal injection molding is hardened using water base binder, and made into a green body. After drying the green body, it is machined by small automatic milling machine. Machined parts are sintered after that, and rapidly manufactured parts are obtained. In this process, the green body has enough strength for machining, and we can use a small, cost-effective milling machine developed for wood or plastic materials. The machining time of the green body is short compared with other material processing. We can obtain low cost rapid prototyping of metallic parts by this green machining process.
