Micro/nano milling tools are usually made of ultra hard materials. Wire EDM (electrical discharge machining) may be the best choice to fabricate these tools conveniently and efficiently. For micro/nano milling tools with complicated three-dimensional (3D) geometries, manually programming method is not applicable. The CAM (computer-aided manufacturing) systems existing in the market don't take the special WEDM (Wire EDM) processes for micro/nano milling tools into consideration. In order to generate the NC programs automatically for the multi-axis WEDM machine to fabricate micro/nano milling tools, a computer assistant system, also called the CAM system, is developed in this paper. The CAM system takes the special WEDM processes into consideration for the fabrication of micro/nano milling tools. First, based on the interfaces and the databases of the CAM system, geometries of micro/nano milling tools, machining conditions for different portions of the tools, WEDM machine tool specifications and controller properties are defined. Second, the manually input tool geometries are verified and WL (wire location) data are generated and verified. Third, simultaneously maximum six-axis CNC programs are generated automatically for the specific micro/nano milling tool. Key techniques for the development of the CAM system are introduced in the paper and micro/nano milling tool fabrication experiment done in this paper shows the efficiency and accuracy of the CNC program generated by the developed CAM system.

“…It was shown that the proposed scheme yielded a unique representation of the ruled surface and could be used to determine directly the tool motion required to machine the ruled surface. Yan et al [4] utilized the Plucker coordinate representation to describe the free-form ruled surfaces of WEDM components and to generate the corresponding tool path. Cheng et al [5] have developed the method to generate the numerical control (NC) programs automatically for the multi-axis WEDM machine, which can fabricate micro/nano milling tools.…”

This paper presents a systematic methodology for producing the numerical control (NC) data required to fabricate complex three-dimensional (3D) ruled surfaces using five-axis computer numerical control (CNC) wire electrical discharge machining (WEDM). The proposed approach commences by using the Denavit–Hartenberg (D–H) notation to establish the ability matrix of the WEDM machine. The Plucker coordinate representation is then applied to design the desired ruled surface in terms of a set of control lines. In addition, an offset ruled surface is derived in accordance with the principles of differential geometry in order to account for the wire radius and spark gap. Finally, the required NC data equations are obtained by equating the corresponding elements of the ability matrix and the configuration matrices of the upper and lower wire guide heads respectively. The validity of the proposed methodology is confirmed by machining a workpiece with a cubic Bezier ruled surface on a commercial five-axis CNC WEDM machine.

“…An early paper on accuracy of taper-cut studied the guide's configuration [2]. Some ruled surface analysis, surface design and tools path generation were studied from viewpoint of mathematics or mechanism design [3,4]. The other proposed solid modeling for analysis of four-axis cutting geometry [5].…”
