摘要：

Electric discharge machining (EDM) is widely used in mould making and die industries, and is also becoming a popular method for making prototypes and parts in aerospace, automobile and electronics industries. Wire EDM is typically used to cut plates and to make punches, tools and dies from hard metals that are difficult to machine with conventional methods. Although simple contours can be programmed and converted into numerical control (NC) codes for a NC wire EDM machine online, the process is time consuming. Some software can take less time, but cannot handle complex shapes. This paper presents a new software tool that can efficiently convert complex shapes into NC wire EDM programmes with a high precision. Geometry processing adopted in the software tool, including view transformation, snapping and breaking algorithms, transformation of arc parameters, and data structure of geometric information is presented.
