Abstract:In order to improve the quality of spinning roller，the concept and function of QFD method are introduced.The user demands are converted to design requirements,process requirements,and production requirements through QFD method，combining 6δ design with robustness design concept，affinity diagrams and house of quality building,and a new R&D plan of dense toothed roller on the base of feasibility analysis is presented.It is pointed out that the QFD method is a concept that converts user requirements to quality features，product configuration，design parameters，technical features and manufacturing parameters，also an effective tool to conduct TQC and implement product quality improvement.Flexible use of the method can improve product quality,shorten R&D cycle,and save investment costs.The new type of dense toothed roller designed and manufactured with the method has good applicability,no straightening on line,no mechanical wave,and the yarn index completely conforms to the 5% level of Uster 2013 communique.The QFD method is technically recommendable in R&D of product,quality improvement,process control and marketing service to achieve cost reduction and efficiency increase for enterprises.
