“…Saito et al [6] proposed a milling process with combination of cross-sectional profiled tool and its axial motion. The cross-section profile has to be initially generated by wire electric discharge machining (WEDM) process, which consumes certain machining time but lesser than that is required to fabricate the complete tool.…”

“…One of the first attempts to exploit CNC capabilities in EDM towards establishing it as a mainstream manufacturing process seems to be due to Saito et al who proposed [3] the concept of traversing simple frame tools to machine cavities. This was eventually advanced further by Bayramoglu and Duffill to include cylindrical [4] and plate [5] tools.…”

a b s t r a c tElectrical discharge milling (ED-milling) is an emerging technology which entails a rotating cylindrical tool that is traversed along a predefined tool path to machine a cavity. This process configuration offers advantages such as minimal time/cost associated with tool manufacture and improved gap flushing, as compared to traditional die-sinking that involves complex three-dimensional tools. Rotating cylindrical tools, however, inherently preclude the machining of sharp features and correspond to increased relative electrode wear; the reduced machining engagement further restricts the machining power which in turn limits the removal rate. To this end, this paper presents a novel tooling concept that relates to a set of standard prismatic tools of an oblong section, which incorporate the favorable functional characteristics of both ED-milling and die-sinking technologies. Aspects of computer-aided manufacture referring to tool selection, sizing and path planning are discussed. The concepts developed are illustrated through the application of an oblong tool that rotates and translates to machine a sample two-dimensional cavity.

“…This is so because a large material removal rate may cause the formed electrode to be damaged easily, owing to the erosive effect of electric discharging on both workpiece and electrode. To increase the flexibility and expand the application areas of EDM machining, a new technology named CNC or contour EDM emerged in the 1980s [1][2][3][4]. This method is different from conventional die sink EDM, in which a formed electrode is used, as it utilizes a standard cylinder made of copper or bronze as the electrode (Fig.…”

This paper introduces a method for rough machining of turbine blades with CNC electrical discharge machining (EDM), which is similar to mechanical milling geometrically and is also modelled by intersections between a cylindrical tool and the workpiece. However, special factors such as DC arcing, electrode wear, and discharging gap compensation have to be considered in the process. These special factors are analysed, and a CAM system catering to four-axis CNC EDM rough machining of turbine blades with a cylindrical electrode is introduced. The tool path generation algorithm has been integrated in an industrial CAD/CAM system (Unigraphics). In addition to machining simulations, real cutting experiments are presented.
