横向卷曲C形屑折断数学模型及试验研究

NEW MANUFACTURING TECHNIQUE-FIXTURE -FREE MANUFACTURING

借助于高速摄影技术，分析了横向卷曲Ｃ形屑的形成与折断过程。提出了一种新的切屑折断数学模型，给出了折断判据，并进行了试验研究与验证。

The concept of fixture-free manufacturing and the new manufacturing mode of fixing-searching-ma- chining are praented . The infomation flow modes and control methods of fixture-free amnufacturing as well as the schems of solving the key problems in system building are given . The experimental system and experi- mental result are introduced . The results of theoretical analysis and experiment show that the presented fix- ture- free manufacturing method is feasible .
