摘要: 五轴双驱车铣复合加工设备具有一次装夹完成全部加工工序的能力,其配套软硬件条件的不足限制了设备功能的发挥。通过增加柔性工装接口提高复合运动变换的效率,基于通用软件开发的专用后置处理可实现快速车铣复合数控编程。在采集设备实时运行数据的基础上利用智能控制算法可实现一定程度上的自适应加工,达到提升车铣复合设备在航空发动机领域智能化应用水平的目的。Abstract: Five-axis turning-milling compound machine tool with dual-drive spindle has the ability to complete all machining procedures by clamping at one time. The lack of supporting software and hardware conditions limits the function of the machine tool. The efficiency of compound motion transformation is improved by adding flexible fixtures interface, and the rapid turning-milling compound NC programming can be realized by special post-processing based on general software development. On the basis of collecting the real-time running data of the machine tool, the intelligent control algorithm can realize adaptive machining to a certain extent, and achieve the purpose of improving the intelligent application level of turn-milling compound machine tool in aero-engine field.

表 1 异常情况监控与处理
监控信号异常情况 可能的原因 处理方法 功率信号突破上边界 撞刀、缠屑、刀具过度磨损、定位错位、装夹不稳 加工日志中生成加工异常数据并记录发生的时间,通过对比该信号和以往加工异常信号的相似度来判断可能的加工异常类型,并针对性处理。 功率信号突破下边界 断刀、崩刃、对刀偏差 监测软件会发出加工异常警报,提醒操作人员及时更换刀具或者进行重新对刀。 -
