基于射流支撑的细长轴加工精度

Research on Machining Precision of slender Shaft With Jet Supportor

细长轴是典型的低刚度零件,在生产生活中有着广泛的应用,由于其刚性较差被认为是机械加工中的难题。专家学者和技术人员都在这方面进行了相关研究,新工艺、新技术层出不穷,而至今还没有一种方法可以高效地加工出质量优异的细长轴。文章对细长轴加工力学模型的进行了分析,并设计了一种以切削液为介质的射流作为细长轴车削的柔性辅助支撑新的加工方法。最后,通过实验验证了射流支撑细长轴加工误差补偿方法的有效性和可行性。

The slender shaft is typical low rigidity part,which is widely used in the production. Because of its poor rigidity,it is a problem in machining. Experts and technical personnel have done relevant research in this area,so new process and new technology emerge very afren but still no method can efficiently produce excellent slender shaft.This paper analyzes the mechanical model in slender shaft machining,and new machining method is proposed by using the jet with the cutting fluid as flexible supportor for slender shaft turning. The experimental results validate the effectiveness and feasibility of the method on machining error compensation with jet supporting for slender shaft.
