摘　　要：在使用深孔钻加工大孔径管板时,由于管板存在变形等原因,导致在孔加工完成后,管板背面会出现管孔质量不合格的现象。本研究意欲通过系统的质量分析手段在兼顾经济的同时解决这一问题,通过对产品的制造过程进行流程分析,找出关键影响因素,对关键因素进行统计分析。以此为依据,寻找经济合理的工艺辅助参数,最终实现改善管板管孔质量的目标。When using deep hole drilling to process large diameter tube plate,due to deformation of tube plate,the quality of tube plate on the back of tube plate will be unqualified after completion of hole processing.This study aims to through the system of quality analysis methods in both economy and at the same time to solve this problem,through the study of the process of product manufacturing process analysis,find out the key influencing factors,the statistical analysis of key factors,on this basis,looking for economic and reasonable process auxiliary parameters,eventually realize the goal of improving the quality of pipe plate holes.
