General Description:
In this project, a compact micro EDM system will be developed and tested for use in precision machining. To achieve high surface quality in a machining process for micro features, micro machining of machining tools will be necessary and electrical discharge machining (EDM) (Fig. 1-4) will be a suitable choice for such purpose. Tooling is an important issue in precision machining which is widely used in many industries for making precision parts.
The students of the project team will gain knowledge and experiences in mechatronic and precision system design and development.
Scope of Work:
(1) Structure. The micro EDM system will of a wire cut type and will have a wire handling and application sub system, a dielectric fluid delivery sub system, and a sub system for workpiece/wire positioning. A pulse current generation sub system will also be used in the proposed micro EDM system.
(2) Requirement. A key requirement is to design and develop a micro EDM system under a spatial constraint. The system size has to be limited to fit to a location of limited space. The micro EDM system is to be compact for mobility.
(3) Background. Currently, an electroplating system is being developed. The electroplating system will be used together with the micro EDM system for precision machining applications.
(4) Tasks. The tasks include literature review of the existing technologies and working principles, specification development, concept design, detail design, modeling and analysis, mechanical system manufacturing, test and adjustment, system performance evaluation under test run and machining conditions.
