摘　　要：为改善纵梁数控等离子切割外观质量,以精益六西格玛DMAIC模型为研究框架,对导致纵梁数控等离子切割外观不合格的影响因素进行分析,建立试验模型,并通过MINITAB软件进行数据分析和结果预测,确定了导致纵梁数控等离子切割外观质量异常的关键因子,制定了纵梁数控等离子切割加工参数设定方案,现场试生产结果表明,优化方案能够有效降低纵梁数控等离子切割外观的不合格率,提升了重型载货汽车车架纵梁的生产质量。To improve numerical control plasma cutting appearance quality of longitudinal beam,the Lean Six Sigma DMAIC model is used as the research framework to analyze the factors leading to unqualified appearance quality of longitudinal beam numerical control plasma cutting.A test model is established,and data analysis and result prediction are carried out through MINITAB software to identify the key factors leading to the abnormal appearance quality of longitudinal beam numerical control plasma cutting.The processing parameter setting scheme of longitudinal beam numerical control plasma cutting is determined.Trial production on the production site indicates that the optimization scheme can effectively reduce the unqualified rate of longitudinal beam numerical control plasma cutting appearance,and improve the production quality of longitudinal beam of heavy truck frame.
