| 摘 要： | 经分析与实验，认为扫描速度与激光功率是影响原型成形质量的两个关键因素，从能量守恒原理出发，结合LOM原型制造工艺的具体要求，建立扫描速度与激光功率之间的正比模型，采用跟踪耦合式控制系统可以实现两者的良好匹配，并能保证LOM原型的成形质量，同时讨论跟踪耦合控制系统的适应性，它不仅适用于LOM原型制造工艺，还适用于FDM，SLS，SLA等多种快速原型制造工艺。 |

Matching Model of Laser Power and Scan Speed in Laminated Object Manufacturing |
|
| Abstract: | Through theoretical analysis and experimental study, the authors believe that sweep speed and laser power are two critical factors influencing quality of prototype shaping in laminated object manufacturing(LOM). Starting from principle of conservation of energy, a proportional model of sweep speed and laser power is set up by combining with the specific demand of LOM prototype manufacturing technology. Good match of them can be realized by adopting control system of tracking and coupling type;and quality of shaping of LOM prototype can be determined.A discussion on the usability of control system of tracking and coupling type is made simultaneously.It is not only suitable for the manufacturing technology of LOM prototype but also suitable for multiple technologies of rapid prototyping manufacturing such as FDM, SLS, SLA, etc. |
