摘　　要：针对某型机钛合金超塑成型口盖数控铣切焊缝时出现切口断裂的问题,分析产生原因,优化工艺方案及数控切削方式。通过试切验证,确定加工参数,对工艺过程进行固化,从技术上避免该问题的发生并总结出薄壁零件加工方法,为薄壁零件的优质加工提供技术支持。Pointing to a certain type of superplastic forming of titanium alloy filler cap CNC milling of weld notch frac-ture problems occurred, the cause of the problem, the optimization technology and CNC cutting are analyzed. Through test verifying, processing parameters are determined to solidify the process. This problem is avoided technically and the thin-walled part processing method is concluded to provide the technical support for high quality machining of thin-walled parts.
