金型抜き方向の自動決定に関する研究 : 遺伝的アルゴリズムによるアプローチ

抄録

Determination of parting direction is the prerequisite for all subsequent processes in mold design. The parting direction is directly related to the location of parting lines and affects the side-core mechanism and the location of gates, ejector pins and cooling pipes. In this paper, a method of obtaining the feasible solutions for parting direction from the 3-dimensional CSG (constructive solid geometry) model is proposed. A genetic algorithm is applied to search for a solution. Some experiments conducted using a computer indicate that the genetic algorithm allows us to obtain the feasible solutions for parting direction.
