Cutting processes the line the content designing that originally time being processed piece appearance being electric spark line cutting , being that the angle carries out electric spark on the part concave angle and point mainly. Whose content is pursued including using the AutoCAD software to draw out a part , is pursue the parametric choice carrying out analysis , blank choice , electricity to the part, the machine tool choice workpiece dress gripping and rectifying CAXA line cutting programming , the part treating and so on, reaches the scheme knowing well that a part processes process from blank to finished product''s, and processes the problem should pay attention to in process and solving thereby
Keywords: Electric spark line；line of cutting handicraft；CAXA line cutting XPsoftware
