光纤激光雕刻有机玻璃工艺研究

Engraving Technology of Synthetic Glass by Fiber Laser

利用光纤激光对有机玻璃的高质量文字雕刻工艺进行了研究。以2.5 mm厚有机玻璃为研究对象,对其的表面凸出、内凹雕刻以及填充和不填充等效果进行了系统的研究,解决了雕刻字体填充时存在的填充不均的现象和雕刻不完整等现象,从而避免雕刻处字体熔凝不良形成的波纹与凹凸不平现象。经过大量试验研究,优化了有机玻璃的雕刻工艺,较佳的雕刻工艺参数为功率为4 W-8 W,速度350 mm/s-500 mm/s,开光延时-200 mm-100 mm,关光延时100 mm-300 mm。

This paper research on Synthetic glass sculpting techniques of higher quality by using the fiber laser.The systematic study on its surface convex,concave inside carve and fill and not fill effects solve to the uneven phenomenon of filling and the complete phenomenon engraving fonts with 2. 5mm thick organic glass as the research object. It avoids engraving fonts fused to form corrugated and uneven phenomenon. After the test,We optimize the laser engraving process find the better carve for the power is 4W-8W,the speed is 350 mm / s-500 mm / s,the switch delay is-200mm-100 mm,and the light delay is 100mm-300 mm.
