Abstract
Metal material, like nickel based alloy and titanium based alloy are prreferred as the priority that used in aerospace components, like blisk, diffuser…etc., and biomedical components, like boneplate. But these materials are difficult to be cut. So the electrical discharge machining (EDM) is the alternative solution. Generally, these components are complex shape and mostly with holes or cavities. So 4-axis to 6-axis EDM process is needed. Although there are plenty of multi-axis EDM equipments all around world but there is no commerical software for multi-axis EDM. To build an executable solution, it relatively fast and convienent by using secondary development of commercial CAD/CAM software. In this thesis, the main propose is to design and develop a module that can produce electrode and corresponding path, according to the degree of freedom of machine and the shape of cavity or hole of the workpiece. And the module can use in pratical machining.
