摘要
通过析因设计实验,研究了工艺参数对氟金云母玻璃陶瓷激光加工孔锥度和热影响区(HAZ)的影响,建立了孔锥度和HAZ厚度与工艺参数之间的回归方程,并对工艺参数进行了优化。实验结果表明,激光加工工艺参数对孔锥度和HAZ的影响程度按强弱依次为电流、离焦量、脉宽和重复次数。此外,孔锥度和HAZ还受电流和离焦量、电流和脉宽之间交互作用的影响。建立的回归方程能够较好地描述孔锥度和HAZ厚度与工艺参数之间的关系,由此获得了最优的激光加工工艺参数:电流150 A,脉宽2 ms,重复次数3次,离焦量2.18 mm。
Abstract
With the factorial design experiment, the influences of laser process parameters on hole taper and heat affected zone (HAZ) of fluorophlogopite glass ceramic are studied. Regression equations between taper, HAZ thickness and laser process parameters are established and the process parameters are optimized. The experimental results show that the laser process parameters are in the order of the current, defocusing amount, pulse width, and repetition number based on their influence degree on taper and HAZ. In addition, the taper and HAZ thickness are also influenced by the interactive effects of the current and defocusing amount, and the current and pulse width. The established regression equation can describe the relationships between the taper, HAZ thickness and laser process parameters. From the regression equation, the optimized laser process parameters are obtained as follows: 150 A of current, 2 ms of pulse width, 3 of repetition number and 2.18 mm of defocusing amount.
