摘　　要：针对大尺寸结构件高精度孔系位置度难保证的问题,提出了测量加工一体化的工艺方法,建立了龙门铣床与卧式镗铣床加工孔时的孔位误差补偿模型。基于数控机床进行孔位预加工,利用激光跟踪仪进行点位测量,重构实测孔位与理论孔位的位置关系,基于误差补偿模型,实现孔位再规划,进而修正加工再测量。以某大型航天器研制为背景,对工艺方法进行了试验验证,结果表明,该工艺方法能有效保证大尺寸结构件高精度孔系的位置度。An integrated measurement and machining method for hole-making is proposed in order to get the high-precision positions of the hole in large spacecraft machining.The error compensation models of hole positions for CNC planer type milling machine and horizontal boring and milling machine are established.The holes are drilled on NC machine,and hole positions are measured based on a laser tracker.The relationship between real position and theoretical position is calculated,and the new hole positions are re-planned based on the error compensation model.The holes are bored according to the new positions,and the real positions are measured again.The method is validated in hole-making of large spacecraft.The results show that it is an effective method to obtain the high-precision positions in hole-making of large workpieces.
