摘　　要：刀具路径干涉问题一直是数控加工中困扰我们的一个问题。特别是在模具加工中进行三维造型软件设计,经CAM软件进行后处理生成加工代码,传输到数控加工中心上进行加工时,干涉现象尤为突出。文章通过对数控加工中心中一个实际零件的加工所产生退刀路径干涉问题进行分析,仔细比对修改前后的代码,查看系统参数,观察实际走刀路径,找出了产生干涉的原因,并提出了解决该问题的办法。Toolpath interference is a problem that straightly puzzles us in the CNC machining. The interference is specially obvious in the mold machining when using 3D software to design, applying CAM software postprocessor to produce codes, transimitting to CNC machining center to machine. The paper analyses the toolpath interference when withdrawing the tool in an actual part machining in the CNC machining center by carefully comparing the modified codes with old codes, looking out the system parameter, observing the actual toolpath, finds the cause of interference and puts forward the solving method.
