摘要
以某动模型芯为例,运用MasterCAM进行数控编程,分别设计了粗加工、半精加工、残料加工、精加工和清角等多种不同的数控铣削刀路,并进行仿真模拟对刀路的正确性进行验证.在编程过程中需要设计辅助线,有助于设计合格的刀路,灵活运用外形铣削命令中的斜降功能,在进行外形铣削时能往复双向切削,在曲面加工时选择"切削顺序最佳化"选项,并设置合理的"步进量百分比"参数,可以减少抬刀次数,提高工作效率.
Abstract
Taking the core of a moving half mould as an example,using the MasterCAM to NC pro-gramming,various NC milling paths such as roughing,semi-finishing,residual machining,finishing,and cleanup processing were designed respectively,and the correctness of the tool paths was veri-fied by simulation.In the programming process,it was necessary to design an auxiliary line in or-der to design a qualified tool path.Flexibly utilizing the inclined descent function in the contour milling command,the reciprocated bidirectional cutting was possible when contour milling was carried out,selecting"milling sequence optimization"option and setting reasonable"percentage of step amount"parameter during surface machining could reduce tool lifting times and improve work efficiency.
