An optimization design strategy for process parameters considering the manufacturing cell performance is proposed to solve the problem that the process parameter design of extruded-blown-molded product is affected by the product quality requirement and the equipment ability. According to the requirement of product quality
the constraint relation between product quality evaluation index and process parameters is established. The regression equation of the influencing relation is obtained via analysis of the experimental data
and the set of process parameters satisfying the quality objective is sought out. The optimal process parameters satisfying both the quality requirement and manufacturing cell performance can be identified by synthetically considering the objective of satisfying the performance of the manufacturing cell
defining the manufacturing cell performance index
and establishing the constraint and optimization function between the process parameters and the manufacturing cell performance index. A case study on the optimization of the parameters in extruding-blowing-molding process is provided to verify the feasibility of the proposed strategy. The results show that analyzing the experimental data by the quality evaluation index and manufacturing cell performance index can optimize the process parameters of the extruding-blowing-molding manufacturing process with satisfactory quality target and manufacturing cell performance. This strategy effectively solves the problem that the process parameters do not match performance stability of manufacturing cell
and ensures product productivity and quality stability.
