在对成形系统分解与综合的基础上 ,提出了成形工艺创新的基本思路。通过对传统有模型砂型制造过程的分析 ,指出导致其柔性较低的主要原因是信息过程与物理过程相对独立。将离散 /堆积成形原理与树脂砂工艺有机结合 ,提出了 CAD模型直接驱动的铸型制造工艺 ,又称无模型铸型制造 Based on the decomposition and synthesis of forming system, the basic idea of ​​forming process innovation is put forward. Through analyzing the manufacturing process of the traditional model sand mold, it is pointed out that the main reason leading to its low flexibility is that the information process and the physical process are relatively independent. The discrete / stacked forming principle and the resin sand process organically, put forward the CAD model directly driven casting manufacturing process, also known as moldless mold manufacturing
