Control method for novel process of laser micro-texturing

College of Mechanical Engineering,Jiangsu University,Zhenjiang,212013,China

摘要

摘要: 鉴于激光表面微造型技术加工金属材料时会带来较严重的负面热效应，提出单脉冲同点间隔多次的激光微造型新方法。通过对运动控制卡与自制的调Q控制卡的软件编程，利用声光调Q技术及伺服控制,完成了运动控制系统与激光系统的协同控制，从而实现激光加工新方法。整个系统通过工控机集中控制，利用该方法能够高效率加工出微观或宏观的造型形貌，且能显著减少激光加工所带来的热效应负面影响。该控制系统可在摩擦副表面加工出优化设计的微观形貌。经实际加工验证，设备能够满足加工要求且能获得较好的微观形貌和表面质量。

Abstract: During the laser surface texturing, the high intensity of the laser beam pulse on the metal material surface results in the negative heat effect. A new processing approach of single pulse one time, repeating at intervals is presented in this paper. The movement control card and self-developed Qswitch card were programmed for coordinated control between laser system and movement control system. The new processing process was realized by the coordinated control and the technique of acoustic-optic Q-switched and servo control. The system was controlled by industrial computer. With the new approach, the micro-dimple and groove can be easily fabricated and the negative thermal effect can be reduced. The required micro-structures can be produced on the surface of friction units.
