【摘要】 本文建立了反映冷镦机生产过程状态特性的模式向量平面，在此平面上，用模式向量的端点规迹刻划产品质量、模具状态，并制定了判断产品质量，模具状态的门限值。通过“自学习”建立控制模型，对生产过程进行在线监控更多还原

【Abstract】 A pattern vector plane is established for showing the dynamic charactiristics of producing process for the multistage cold header. The movementof the end of pattern vector on the plane indicates the quality of the product and stage of the model during producing. A criterion for the quality of the product is desoribed. By “self learn ”, the maths model is established. Using vector mothos, the machining process is monitored on line.更多还原
