In the present work, laser beam drilling of a fabricated basalt–glass hybrid composite has been done. From the experimental results, a safe machining zone pertaining to high drill quality with minimum heat affected zone and maximum hole-circularity has been predicted. The prediction of the zone has been done by mathematical modeling and optimization using artificial neural network merged with multi-objective genetic algorithm. The acquired zone has been confirmed by performing validation experiments. From the results, it is evident that the predicted range is capable of minimizing the heat affected zone with acceptable hole-circularity. Moreover, the variation in hole-circularity and heat affected zone with respect to the input drilling parameters has also been explored.

新型混合复合材料微钻孔过程中的热影响区 (HAZ) 分析

在目前的工作中，已经完成了制造的玄武岩-玻璃混合复合材料的激光束钻孔。根据实验结果，预测了一个与高钻头质量相关的安全加工区，具有最小的热影响区和最大的孔圆度。区域的预测是通过数学建模和优化使用人工神经网络与多目标遗传算法相结合来完成的。获得的区域已通过执行验证实验得到确认。从结果来看，很明显，预测范围能够以可接受的孔圆度最小化热影响区。此外，还探讨了孔圆度和热影响区相对于输入钻井参数的变化。
