Development of High-Productivity Machine for Precision Dies and Molds

Abstract

In general, many processes are required to produce precision dies and molds, including cutting, electrical discharge machining, grinding and polishing. In particular, since cutting with small-diameter tools on current machines is difficult for extra-small precision dies and molds, productivity and precision are extremely low. This research project involved the creation of new machining technology for the use of small-diameter tools, and the development of machine tools capable of streamlining the machining processes while maintaining consistent quality, with the ultimate goal being to reduce die/mold lead times while decreasing cost. The project resulted in an increase in production efficiency of between two to five times for actual machining applications, with efficiency being boosted over tenfold on applications most suited to the new technique.
