摘要: 产品质量是企业树立品牌的前提和增加企业效益的源泉。针对金属冷热切圆锯片,首先分析其生产工艺流程;然后,利用质量功能展开(Quality Function Deployment,QFD)方法,应用质量屋将客户反映的需求展开成为质量特性,再将质量特性展开为关键工序,并从市场竞争性和技术竞争性两方面综合考虑,确定企业质量改进关键点;最后,对关键工序热处理进行多因素多指标正交试验设计,以寻求影响热处理因素:材质、淬火温度、淬火时间、回火温度、回火时间和油温的最优组合及其影响因素主次。降低了企业冷热切圆锯片的不合格品率,提高了顾客满意度,效果显著。

关键词: 质量功能展开, 正交试验设计, 质量改进, 圆锯片

Abstract: Product quality is the premise for the enterprise to establish the brand and the source of enterprise benefits,for the metal hot and cold cutting circular saw blade,firstly,the production process of the blade was analyzed;Then,Quality Function Deployment (QFD) method was applied by the use of quality house,and the customer needs were developed into the quality characteristics,and the quality characteristics were developed into the key processes,considering the analysis from two aspects of market competition and technological competition,the key process which need to improved was determined by the enterprise.Finally,the treatment of multi factor and multi index orthogonal test design of the heat treatment process was designed,to seek the optimal combination of the influence factors of heat treatment process,such as materials,quenching temperature,tempering time,tempering temperature,tempering time and the oil temperature.Not only the hot and cold cutting circular saw blade rate of unqualified products was reduced,and customer satisfaction was improved,the significant is effect.

Key words: quality function deployment, orthogonal experiment design, quality improvement, circular saw blade
