Many microslits are typically manufactured on quartz substrates and are used to improve their industrial performance. The fabrication of microslits on quartz is difficult and expensive to achieve using recent traditional machining processes due to its hardness, electrically insulating nature, and brittleness. The key objective of the current study was to demonstrate the fabrication of microslits on quartz material through a magnetohydrodynamics (MHD)-assisted traveling wire-electrochemical discharge micromachining process. Hydrogen gas bubbles were concentrated around the entire wire surface during electrolysis. This led to a less active dynamic region of the wire electrode, which decreased the adequacy of the electrolysis process and the machining effectiveness. The test results affirmed that the MHD convection approach evacuated the gas bubbles more rapidly and improved the void fraction in the gas bubble scattering layer. Furthermore, the improvements in the material removal rate and length of the cut were 85.28% and 48.86%, respectively, and the surface roughness was reduced by 30.39% using the MHD approach. A crossover methodology with a Taguchi design and ANOVA was utilized to study the machining performance. This exploratory investigation gives an unused strategy that shows a few advantages over the traditional TW-ECDM process.
许多微槽通常在石英基板上制造，并用于提高其工业性能。由于石英的硬度、电绝缘性和脆性，使用最近的传统加工工艺在石英上制造微槽既困难又昂贵。当前研究的主要目标是通过磁流体动力学（MHD）辅助的行丝电化学放电微加工工艺来演示在石英材料上制造微槽。在电解过程中，氢气气泡聚集在整个丝表面周围。这导致丝电极的动态区域活性降低，从而降低了电解过程的充分性和加工效率。测试结果证实，MHD对流方法能更快地排出气泡，并改善了气泡散射层中的空隙率。此外，使用MHD方法时，材料去除率和切割长度的提高分别为85.28%和48.86%，表面粗糙度降低了30.39%。采用田口设计和方差分析的交叉方法来研究加工性能。这项探索性研究给出了一种未使用过的策略，该策略相对于传统的行丝电化学放电加工工艺显示出一些优势。
