“…This decreased the machining stability, efficiency, surface integrity, and shape accuracy of machined holes. Zhu et al (2010) and Wang et al (2010b) proposed a wedged tube electrode (Figure 41b) to modify the electrolyte flow field and consequently improved machining accuracy and stability. Zhu et al (2010) demonstrated that the wedge-shaped electrode was a feasible method to improve the shape accuracy of machined holes.…”

“…Based on STED process with vacuum extraction, Zhu et al (2010) and Wang et al (2010b) developed a new method for making inclined holes using a wedged tube electrode, as shown in Figure 41. When using a traditional tube electrode, the imbalance of electrolyte flow field distribution sometimes caused abnormal material dissolution, sparking, and even short circuits.…”

2 A cooling hole is important structure of turbine blades for high-performance aircraft engines. It is very challenging to manufacture cooling holes in superalloys including nickel-based and titanium alloys. This article aims to provide a critical assessment on the major types of machining processes for manufacturing cooling holes. The process mechanism, efficiency, form accuracy, and surface integrity of the state-of-art of four machining processes, i.e., mechanical drilling (MD), electrical discharge drilling (EDD), laser drilling (LD), and electrochemical drilling (ECD) have been thoroughly analyzed and compared in details. The future challenges and future potential research directions for the machining processes are also discussed.

“…Thanigaivelan et al researched the mechanism of drilling microholes in copper by ECM and analyzed various processing parameters by Taguchi's quality design concepts [10]. Zhu et al proposed an electrochemical drilling method of multiple holes in which reverse electrolyte flow is achieved in the way of electrolyte-extraction, instead of traditional forward electrolyte flow which often causes poor electrolyte flow conditions and so an unstable machining process [11]. Natsu et al used electrolyte jet machining to process microdimple arrays of 300 m in diameter [12].…”

Electrochemical machining is widely used in the processing of difficult-to-machine metal materials. And through-mask electrochemical machining is a very important technology in the processing array structure of difficult-to-cut metal materials. Traditional through-mask electrochemical machining always uses a photoresist as the mask. The production process of a mask is complicated, and the mask cannot be reused. In this paper, through-active-mask electrochemical machining to process array structure in difficult-to-machine metal materials was investigated. Compared with traditional electrochemical machining masks, a copper-clad laminate is used to make the mask by mechanical machining in through-active-mask electrochemical machining. Also, the mask does not stick together with the workpiece but covers the workpiece by mechanical compaction, so the mask can be reused. In order to ensure the mask is in close contact with the workpiece, we need to arrange many compaction circular cylinders within the flow channel. The influences on electrolyte flow of compaction circular cylinders were investigated. The distribution of the compaction circular cylinders affects the electrolyte flow state, thereby affecting the processing. By analyzing the electrolyte flow state for the different distributions of compaction circular cylinders, one can find the best distribution of compaction circular cylinders for the required processing.
