快速成形工艺过程的描述与分析

Description and analysis of rapid prototyping processes

为了定量研究快速成形过程 ,需要建立其数学模型。针对材料中对成形有重要意义的堆积参量 ,采用矩阵方法 ,提出了材料成形状态矩阵以描述材料在快速成形全过程和各个空间位置的团聚状态的变化。对快速成形的成形机理和离散堆积思想进行了数学描述 ,提出了伴生函数以描述快速成形过程中伴生的其它物理化学现象。在数学描述的基础上 。

A mathematical model is developed for rapid prototyping (RP) using the conglobation parameter which relates to material forming and the material forming status matrix (MFSM) to describe material changes in space using RP processes. The RP mechanism and discrete deposition principle are modeled with MFSM. The accompanying function (AF) is proposed to describe other phenomena in RP processes. Some novel ideas for RP technology are introduced based on this mathematical model.
