Development of a New Technology for Trimming of Dual Phase Steels

This paper describes the development and investigation of a new technology for trimming of dual phase steels and provides a comparison with other trimming processes. This technology utilizes an elastic support of the offal, sharp upper trim knife and angled lower trim knife. Such a configuration allows for a high quality trimmed surface with little or no burr and without slivers over a wide range of cutting clearances.
