摘要
分析了作为一种高端加工方式的五轴联动加工在提高工件加工质量方面广泛的应用前景。在汽车覆盖件拉延模具成型曲面加工过程中,通过控制五轴联动数控机床的刀具轴矢量,可以有效地避免静点切削、使用更短的刀具加工陡峭侧壁,并可做到使用单一程序加工完工件整个有效型面部分,减少接刀痕迹,从而有效提高覆盖件拉延模具型面加工质量。
Discuss the application of 5 axis simultaneous machining,which is a kind of advanced machining mode,it has broad application foreground in improving part machining quality.In the process of automobile cover die machining,by controlling the tool axis of the 5 axis machining center,the 0 cutting velocity of the ball nose tools can be avoided,the steep wall of part can be machined using shorter tools,also,the whole valid molding surfaces can be machined using one NC program,so that the tool cutting mark can be reduced,the quality of the automobile cover die can be highly improved.
