“…流，满足了激光组合增材制造技术的使用要求 [13] 。同样四束侧向送粉工作头也广泛应用于工业应用，如美国的 Martin [14] 研制了四路侧向送粉工作头，同时应用于修复不规则裂纹的受损区域，提高了激光组合制造的灵光外同轴送粉工作头是将光束路径、粉末通道、外层导气通道和冷却水通道连接成一体 [16][17] ，如图 3 所示。由于粉末的环形流道，粉末均匀分布并与激光束同心，所以在各个方向加工时，粉末的利用率基本是不变的，从而解决了扫描方向性的问题，保证了加工过程中熔覆层高度不会发生变化 [18] 。而且这种送粉工作头为熔池提供了一个保护气氛，能够防止加工过程中材料的氧化。但这种送粉工作头结构复杂，粉末与气流之间会相互影响，对于粉末流控制更加困难，粉末在一个小区域内很难实现汇聚，使得粉末的利用率降低 [19][20] 。为解决光外同轴送粉工作头粉末汇聚性的问题，美国的 Whitfield [21] 将送粉工作头设计为激光光束变换…”

Laser combination additive manufacturing (LCAM) is a new manufacturing technology method that has been developed rapidly in recent years. The quality of LCAM is influenced by various factors, among which powder feeding head is a key factor in particular, its performance directly affects the quality and precision of LCAM. The structure and the latest research progresses are introduced mainly from the lateral powder feeding head, coaxial powder feeding head and intelligent powder feeding head, and the characteristics of three types of powder feeding head are analyzed. Based on the main problem of three types of powder feeding head, the future development of powder feeding head is prospected.

Laser remanufacturing system is a new advanced manufacturing technology, which is based on robot, high-tech surface techniques and rapid prototyping technology. It has been developed quickly in recent years. Due to laser remanufacturing is a multi-species and small volume production, however, robot teaching programming is very difficult to meet its requirements. An off-line programming system for laser remanufacturing is developed based on FANUC's industrial robot R-2000iB/125L in this paper. Mathematica6.0 is used as the path planner. LabVIEW is automatic programming tool. ROBOGUIDE is used as simulation environment. Using the path planner simple and complicated curves in CAD can be transformed into moving path and motion instructions can be created automatically. After testing, robot end moves smoothly as expected and performs well.

The posture of the laser head is requested strictly in the cutting along the intersecting line of laser processing robot, and the position model of intersecting line is complex. In order to meet these demands, a continuous trajectory planning method which is used to controlling the position and posture of laser head is proposed. For the normal direction of the surface keeping coaxial to the laser head, the posture of the laser head can be known by solving angle which is between the laser head and the cutting surface. A design on 3D visualization simulation for the laser processing robot under the VC++6.0 environment and the OpenGL is introduced. The simulation results show that the trajectory planning method can effectively control the position and posture of the laser head.
