Abstract


With the wide application of micromechanical engineering , many countries invest a lot of funding to study micro-mechanical method of manufacturing - microfabrication technology . Micro-EDM wire cutting their high processing efficiency , better processing quality, other microfabrication methods irreplaceable advantages in many aspects of the complex three-dimensional parts can be processed to become the focus of one of the objects in the field of micro-machining . So far, the research focuses on the development and production of fine WEDM applications of micro-EDM wire cutting , basic theoretical research has been lagging behind , especially for micro- EDM wire cutting surface morphology understanding in there is a deviation between theory and practice , surface morphology and conventional machining and EDM surface . The traditional measurement methods and measurement theory is not suitable for micro- EDM wire cutting surface , which severely restricted the further development of micro-EDM wire cutting . In this paper, uniform design method to processing micro-EDM wire cutting specimen , not only reduces the number of tests to ensure the comprehensiveness of the study does not affect the conditions of the process of law ; scanning probe microscopy scanning the specimen processing , access to 3D Surface Topography data ; separation reconstructed wavelet analysis method on the surface morphology , including noise reduction , extraction plane and separation surface morphology ; for micro EDM wire cutting surface morphology and functional applications put forward the corresponding characterization parameters , to create micro-EDM wire cutting surface morphology and function evaluation system , provide the basis for the establishment of a surface evaluation criteria for micro-EDM line cutting ; summary of each parameter variation , the application of regression analysis to establish the surface morphology and processing parameters multiple nonlinear regression equation between fine EDM wire cutting process regular study provides a theoretical basis for the development of micro- EDM wire cutting technology has a certain practical significance .
