摘　　要：多工序制造过程在加工产品质量特征时出现的加工误差存在相互影响,因此为了保障产品的加工质量,定义了误差自修正能力指数来评价多工序制造过程对产品质量特征加工误差的补偿能力,并提出一种偏最小二乘回归方法应用于确定最后一道工序的加工误差与上游工序加工误差之间的关系,从而采取相应的调整措施来减少误差、保证最终的加工质量.In a multi-operational machining process,the deviations of quality characteristics affect each other.In order to ensure product quality,the index of deviation self-correction capabiUty is defined to evaluate this feature for multi-operational machining process.A partial least squares regression method is proposed to set up the relations between upstream operations and the last one.The regression result helps engineers to identify key processes with respect to their impacts on the last one,and possible solutions to reduce the deviation and ensure the product quality.
