Abstract

In standard P/M (Press-Sinter) technique, it is difficult to make under-cut shape parts. In this development, undercut shape sprocket of whole circumference is made by CNC press and new designed die and tools. This paper describes the details of this development. 1) Features of CNC press and new designed die and tools for under-cut shape compacting. 2) How to eliminate cracks and barrs of this under-cut shape parts. 3) How to achieve the even density of this complex parts. 4) How to keep the dimensional tolerance of this parts.
