2、修正缺陷、優(yōu)化工藝參數(shù)的思維過程。基于上述智能模型開發(fā)出了相應的軟件系統(tǒng),并通過與控制器的通訊實現(xiàn)與注塑機的集成,實際案例驗證表明該系統(tǒng)正確有效??蓱糜趯嶋H生產(chǎn)。關鍵詞:注射成型;實例推理;代理模型;模糊推理;注翅機;工藝參數(shù)優(yōu)化中圖分類號:TQ320文獻標識碼:A文章編號:0438—1157(2009)11—2854一08InteIligentsettingandOptimizationOfprocessparametersforinjectionmoldingmachineZHAoPeng,ZHoUHuamin。LIYang,LlDequn(Sf口feKPyLn60,
