摘要
深槽类零件有着出色的导向、传递运动或动力的作用,在诸多领域得到了广泛应用。以飞机叶轮零件为例,分析了深槽类零件在加工时出现振纹、扎刀、表面粗糙度不达标的主要影响因素,针对具体问题提出了切实可行的解决方案,并融合数控仿真软件验证了方案的可行性。结果表明:将割刀的方形刀杆改为圆形刀杆可以明显提升刀具强度,能有效抑制刀具振动现象;采用间歇进给和闭环刀路两种方式相配合的方法,能明显改善深槽加工时切屑排出困难的现象,且能显著提升深槽表面加工质量。
Deep groove parts have been widely used in many fields,and they have excellent guiding,transmitting motion or power functions.This article takes aircraft impeller parts as an example to explore the main influencing factors of vibration patterns,knife cuts,and substandard surface roughness in the processing of deep groove parts.This article proposes practical and feasible solutions for the specific problems of deep groove machining,and verifies the feasibility of the solutions by integrating numerical control simulation software.The results show that changing the square shank of the cutting tool to a circular shank can significantly improve the strength of the tool and effectively suppress the phenomenon of tool vibration.The combination of intermittent feed and closed-loop tool path can significantly improve the difficulty of chip discharge during deep groove machining,and significantly enhance the surface machining quality of deep grooves.
