金属板材分层渐进成形技术及其有限元模拟

本文介绍了金属板材分层渐进成形技术。由于金属板材分层渐进成形的工艺较复杂 ,各种参数及加工轨迹很难用实验方法确定 ,如何选择合理的工艺参数来得到理想的加工工件成为问题的关键。根据金属板材分层渐进成形为多工步成形的技术特点 ,提出了金属板材分层渐进成形的有限元模拟方案

SHEET METAL DIGITAL PLASTIC FORMING PROCESS AND ITS FEM SIMULATION

This paper introduced the sheet metal layered incremental forming process. Since the technology of the sheet metal layered incremental forming process is relatively complicated,and various parameters and process mark are difficult to choose by the experimental methods it is the key factor for sheet metal digital forming process to choose reasonable technology parameters to get ideal process workpiece.The sheet metal layered forming process is a multi\|stage forming process,the paper introduced FEM simulation project of sheet metal layered forming process.
