“…Except working medium, the electric parameter such as working current, pulse duration and so forth, has influence on the surface integrity. Therefore, an orthogonal design for multi-factor experiments is employed to select the proper machining parameters [8,9].…”

In wire electro-discharge machining with high traveling speed(WEDM-HS), the emulsion is used as working liquid. Because there exists a functional electrolyte, this affects the surface quality of workpiece machined. An investigation has been made into the machining feasibility when the gas or air is employed as processing medium. The first cut on workpiece is done with emulsion, and then air or distilled water is used for the second cut and multi-cuts. After machining, the surface quality and mechanical performance of the specimen under different conditions are compared. The experimental results show that air and distilled water have little influence on the surface roughness, but they can improve the mechanical performance such as the increase of hardness and the decrease of surface cracks. An orthogonal design is adopted to optimize the electric parameters and cutting passes so as to obtain the best integrative result. The experiment with air as medium reveals that it is a feasible and effective way for eliminating the electrolytic layer and improving the surface integrity of workpiece.

“…The EDM process has been used in cutting electrically conductive materials and then PCDs [1,76]. Guo et al [77,78] and Lu et al [79] introduced this process to polish CVD diamond films. A thin layer of electrically conductive material is needed before polishing for a dielectrically conductive CVD film.…”

“…The proposed methods include the lapping, grinding [1], coupled-abrading [2] and thermochemical polishing assisted by metal powder [3] such as rare-earth [4] and manganese powder [5]. The high energy beam such as laser [6], ion beam [7], abrasive water jet [8] and electrical discharge [9,10] were also used to polish diamond films. In recent years, chemical/ mechanical polishing has been regarded as a promising method [11].…”
