Abstract

Abstract:

This paper presented a new type of precision cropping process method with rotary striking by which high quality cutting surface can be obtained. The theoretical mechanism of this new process was analyzed and discussed comprehensively. The experimental study was performed and exhibited with successful results. A new measurement method was proposed and applied to assess the quality of the cross-section. The results show that this new cropping process can crop the various material and diameter bars, and the cropped billets can meet entire requirements for the precision technology of plasticity. In some cases, they can be directly used in the subsequent process.

Key words: metal bar, precision cropping, process, experimental study
