关于SPC技术在汽车白车身制造中的应用研究

Research on Application of SPC Technology in Automobile Bodyin White Manufacturing

白车身制造精度是汽车外观质量的载体,直接影响整车外观匹配和整体性能进而影响客户满意度和整车品牌形象。我国自主品牌汽车要想在竞争中赢得一席之地,提高汽车白车身制造精度是关键所在。SPC统计学方法对白车身制造过程进行质量控制并进行分析,根据分析结果采取相应措施,从而达到过程异常预警、降低过程浪费、提升过程能力,从而确保白车身制造精度。

The manufacturing accuracy of the body-in-white is the carrier of the appearance quality of the car,which directly affects the appearance matching and overall performance of the vehicle and thus affects customer satisfaction and the brand image of the vehicle.In order to win a place in the competition,China's self-owned brand cars are the key to improving the manufacturing precision of automobile body-in-white.The SPC statistical method carries out quality control and analysis on the body-in-white manufacturing process,and takes corresponding measures according to the analysis results,thereby achieving process abnormality warning,reducing process waste,improving process capability,and thus ensuring the manufacturing accuracy of the body-in-white.
