Electrical discharge drilling (EDD), a non-contact manufacturing technology that brings the potential to fabricate microholes at low cost and relatively high efficiency, has aroused extensive attention at home and abroad. However, the surface/subsurface defects and forming accuracy inherited from the EDD process can significantly impede the mechanical properties and weaken the usage performance of as-micro holes parts and components, probably challenging this process’s reliability and reproducibility. The advancement of simulated technique and characterization detection currently opens up a more a more intuitive and deeper research of micro holes machined by the EDD process. Given that, the paper systematically states the material removal mechanism, debris escaping path, surface/subsurface defects formation, mitigation strategies and improved measures of micro holes fabricated by the EDD process. Consequently, based on current limitations and challenges, hybrid process and theoretical breakthrough play a significant role in future research on the microhole fabricated by the EDD process.
