Simulation about Machining Deep Hole in Sheet

Abstract:

It is becoming a development direction to study green forming process in mechanical. The processing technology of machining deep hole in relative thin sheet is a kind of green mechanical processing technology in this paper. The process uses the friction between driller and workpiece and plasticity of workpiece to form hole. The new technological process not only saves material, but also saves man-hours, and the workpiece has a good piece of assembly. In this paper, the forming process of deep hole on thin sheet was simulated, and some effect factors of forming hole were studied, such as the stress, temperature and shape of forming area, etc. The forming simulation is proved to be feasible by the test in this paper. The study results are useful to improve the machining parameters, and laid a foundation for further research on forming deep holes process on thin sheet metal by friction heat.
