摘要
讨论了用球头铣刀进行曲面加工时共振安定界限的预测方法 ,重点分析了法向方向角对共振安定界限的影响 .以Tobias稳定切削理论为基础 ,将Altintas的有关分析方法扩展到曲面切削 ,通过建立当量比切削指数 ,可绘出曲面铣削加工理论安定界限图 .
An algorithm has been developed to predict the stability lobes in ball end milling to investigate the influence of normal direction angle at cutting point on the stability. An analytical expression is based on the Tobias dynamics analysis and an extension of Altintas to the cutting of sculptured surface. By developing an equivalent cutting force coefficient method, the theoretical stability lobes can be drawn during cutting of sculptured surface. The analysis helps to control chatter during cutting of sculptured surface.
