摘要 激光打标技术是在近二十年来兴起的一种标刻工艺，在机械制造领域中具有十分广泛的应用，具有加工速度快、加工精度高、污染小等优点，激光打标技术正在逐渐代替传统的机械打标技术，如冲压、印刷、化学腐蚀等。光纤激光打标机电光转换效率高，达到30%以上，整机体积小，输出光束质量好，可靠性高。对脉冲激光扫描系统的精确控制进行研究具有重要意义。
光纤激光打标系统是由脉冲光纤激光器及控制箱、光学扫描系统、冷却系统及工作台和控制系统及软件组成。本文首先介绍了光纤激光器的研究现状、激光打标行业的研究现状以及对打标系统中振镜失真问题的研究现状，并对光纤激光打标系统的各个组成部分、原理和打标软件Samlight进行了详细的介绍，在此基础上使用Samlight软件配合脉冲激光扫描系统对工件进行打标的精确控制研究，准确地输出了文字、条形码、复杂的图像，并对工艺参数的控制所引起的不同粗糙度做了研究。
本文使用Surfcom 130A 表面粗糙度仪来探测被打标工件的表面粗糙度，得出了精确控制打标机输出的参数是：扫描速度为3000mm/s，激光输出功率20W，作用次数2次。在此实验条件下，能获得最佳的粗糙度值，进而工件的打标质量最佳，实现了对脉冲激光扫描系统的精确控制。

Study on Accurate Controlling of the Pulsed Laser Scanning System
Abstract:Laser marking technology is a new carving process in the past two decades. It has a very wide range of applications in the fields of mechanical manufacture, it has fast processing speed, high precision and little pollution, laser marking technology gradually replacing the traditional mechanical marking technology such as stamping, printing, chemical corrosion, etc...Fiber laser marking machine has a high electro-optic conversion deficiency reaching more than 30%, the volume is small, the output beam has high quality and high reliability. It is important to research the accurate controlling of the pulsed laser scanning system.
Fiber laser marking system is composed of pulsed fiber laser and control box, optical scanning system, cooling system and the work table and control system and software. This paper firstly introduces the research status of distortion of laser galvanometer and the present situation of optical fiber laser marking industry the marking system, then introduce the various marking system of fiber laser components, principle and the marking software Samlight are introduced in detail, based on the use of Samlight software with pulsed laser scanning system of the precise controlling of marking on the workpiece, accurately output image and text, bar codes, some complex graphical, and the control of process parameters caused by the different surface roughness is studied.
In this paper, using the Surfcom 130A surface roughness instrument to detect surface marked workpiece roughness and conclude that the parameters of the precise control of marking machine output is :on the condition that the scanning speed is 3000mm/s,the laser output power is 20W and the effect of frequency is 2 times, we can obtain the roughness value of the best, and then the marking quality best,to achieve precise control of the laser scanning system.
