| 摘 要： | 基于新LOM方法和热扩散工艺，以1.0mm数量级的不锈钢板做造型材料，尝试了金属功能零件的分层快速制造，介绍了新LOM方法的原理，进行了金属分层板的连接实验和样模制作。研究结果表明，新LOM方法加工的零件曲面光滑，没有明显的台阶效应；热扩散焊在堆积成形方向上尺寸变化小，且为系统误差，结合强度达到100MPa；零件最大综合制造误差为0.485mm，但大部分位置处的误差在0.3mm以下。

| Abstract: | In this paper, a new attempt, which is based on New LOM process and diffusion welding technology and using stainless steel sheet of 1. 0 mm as modeling material, is proposed for Laminated Object Manufacturing of metallic functional parts. New LOM principle of the method is introduced by carrying on the connecting experiments of metallic slice sheet and making samples. The results show that the surface of the samples manu- factured by new LOM process is so smooth that obvious stair step may be observed, shrinkage of the size in the stack direction caused by regular errors is small, shearing intension of well diffused section is more than 100 MPa, and the maximum manufacturing error is of 0. 485mm, the error is mostly less than 0. 3 mm. |
