GATE TYPE SELECTION BASED ON FUZZY MAPPING

0 INTRODUCTION(Mould conceptual design is the most important phase of mould design. The main characteristic of this phase is a linear flow of design, with minimal number of iteration 1]. The decisions made during this phase are of high level and have a direct influence on performance of the mould and development costs. Within this phase there are many operations that have to be carried out, one of which is gate type selection. Although numerical simulation approach could be used to optim…

GATE TYPE SELECTION BASED ON FUZZY MAPPING

Gate type selection is very important for mould design. Improper gate type may lead to poor product quality and low production efficiency. Although numerical simulation approach could be used to optimize gate location, the determination of gate type is still up to designers' experience. A novel method for selecting gate type based on fuzzy logic is proposed. The proposed methodology follows three steps:Design requirements for gate is extracted and generalized; Possible gate types (design schemes) are presented; The fuzzy mapping relationship between gate design requirements and gate design scheme is established based on fuzzy composition and fuzzy relation transition matrices that are assigned by domain experts.
