| 摘 要： | 引入回归正交设计(ORD)方法,利用逐步回归模型得到了激光快速成形(LRF)工艺参数以及它们之间的交互作用对沉积层尺寸影响显著的因素。其中,对沉积层高度影响显著的因素是送粉率和扫描速度,对单道沉积宽度影响显著的因素是光斑直径、扫描速度、激光功率与光斑直径的交互作用。同时也得到了主要影响因素与沉积层尺寸的定量关系,并验证了其准确性。

| Abstract: | The most effective factors to the dimensions of deposit layers in the laser rapid forming (LRF) processing have been achieved through using orthogonal regression design (ORD) and regression analysis method. The most effective factors on the height of deposition layer are powder feeding rate and scanning velocity. And the most effective factors on the width are spot diameter, scanning velocity, and interaction between laser power and spot diameter. The approximate relations between the deposition layer dimensions and their most effective factors are obtained and validated. |
