倾斜角从0°到60°变化的零件和多角度零件由法向切片组成。它们是基于激光内送粉技术和KUKA机器人的单点沉积和间歇加工而成的。通过ANSYS热力学仿真和相应的实验，得到了最优加载时间。实验结果表明，成形细长结构件精度高，截面尺寸均匀。最大相对误差为1.6%，表面粗糙度为1.98~2.47 mm。不同倾角下零件的显微组织相似，无明显缺陷。
The part with an incline angle changing from 0° to 60°and the part with multi-angle are formed by normal direction slices. They are generated by the single point deposition and the intermittent processing based on inside laser powder feeding technology and KUKA robot. The optimized loading time is got from the ANSYS thermo dynamics simulation and corresponding experiments. The experimental results indicate that the forming slender structure part has a high precision and uniform section size. The biggest relative error is 1.6% and the surface roughness is 1.98~2.47 mm. The microstructures of the part at different incline angles are similar without apparent defect.
