Automatic identification algorithm of EDM area based on geometric features
In this paper,an automatic identification algorithm of electrical discharge machining(EDM)region based on geometric feature analysis is presented.Initially,the concave area in the mold is identified based on the concave edge adjacency diagram,the bottom surface of the concave area is identified based on the surface normal direction and then projected.Subsequently,the complex concave area is segmented and integrated based on the inflection points of the bottom projection contour,and the bottom projection contour is analyzed based on four basic features to identify the EDM area.Finally,three kinds of modeling methods are proposed to complete the automatic modeling of the electrode.The algorithm is implemented based on UGOpen,and the feasibility of the algorithm is verified by using the actual engineering mold.
