摘　　要：机匣是航空发动机的重要部件,在机加工后机匣棱边区域会存在明显毛刺,从而严重影响二次定位及装配精度,进而影响机匣质量。针对目前工厂采用人工磨抛去毛刺方式存在的稳定性较差,过、欠抛现象频繁的问题,提出了一种利用超硬磨料弹性工具的机器人抛光自动去毛刺方法。首先,搭建机匣棱边去毛刺工艺系统,然后基于该系统实现超硬磨料工具的选择和在线编程。最后开展抛光去毛刺工艺参数优化实验,并在典型航空后机匣零件上进行验证。试验结果表明抛光后棱边倒角半径约0.1 mm,相邻区域过渡较为顺滑,加工工时约为3 min,抛光轮使用寿命稳定,从而为航空机匣自动化去毛刺提供了可行方案。Casing is an important part of aero-engine,there exist burrs in the edge of casing after machining,which will seriously affect the secondary positioning,assembly and manufacturing accuracy.Aiming at the problems of poor stability and over/under polishing of manual deburring in factories,an automatic deburring method of robot polishing using superhard abrasive elastic tools is proposed in this paper.Firstly,the deburring process system of casing edge is built,and then the selection and teaching programming of superhard abrasive polishing tool are realized.Finally,the optimization experiment of polishing process parameters is carried out and verified on a typical aero-engine rear casing.The results show that the edge filter radius is about 0.1 mm,the transition of adjacent areas is smooth,the processing time is about 3 min,and the polishing tool life is acceptable,which provides a feasible method for automatic deburring of casing.
