| Abstract: | Multi-processdraw-spinning(MPDS) process is affected by several process parameters and the forming mechanism is complex To properly determine the processing parameters is fundamental to the quality and size precision of the spun parts Therefore, it is important to investigate the effects of parameters on the forming process in order to produce high quality product The paper represents a investigation by elasto-plastic finite element to the multi-process draw-spinning, and illustrates comparisons of distributions of stress and strain affected by different parameters occurred during the process |
