凸耳镜头广泛用于三维展示行业。常规的膜状透镜成分由塑料制成，其热稳定性较低。一种替代方法是使用玻璃代替塑料作为毛镜晶状体成分材料。在精密玻璃成型过程中，单晶硅通常用作模具材料。但是，与硅切割的临界深度相比，很难制造具有较大特征尺寸的透镜透镜硅模具。为了解决使用常规的钻石切割方法加工透镜透镜硅霉菌的问题，例如，加工效率低和严重的工具磨损，提出了一种混合加工方法，该方法将激光消融和钻石切割相结合。进行了一项可行性研究，以研究使用这种方法制造透镜透镜硅霉菌的可能性。系统研究了激光参数和加工参数对加工性能的影响。实验结果表明，这种混合加工方法可能是制造透镜透镜硅霉菌或其他类似微观结构的一种可能的方法。
Lenticular lenses are widely used in the three-dimensional display industry. Conventional lenticular lens components are made of plastics that have low thermal stability. An alternative is to use glass to replace plastic as the lenticular lens component material. Single crystal silicon is often used as the mold material in the precision glass molding process. It is, however, difficult to fabricate a lenticular lens silicon mold that has a large feature size compared to the critical depth of cut of silicon. In order to solve the problems of machining lenticular lens silicon molds using the conventional diamond cutting method, such as low machining efficiency and severe tool wear, a hybrid machining method that combined laser ablation and diamond cutting was proposed. A feasibility study was performed to investigate the possibility of using this method to fabricate a lenticular lens silicon mold. The influence of the laser parameters and machining parameters on the machining performance was investigated systematically. The experimental results indicated that this hybrid machining method could be a possible method for manufacturing lenticular lens silicon molds or other similar microstructures.
