Abstract:In order to solve the problem of intelligently machining of profile and characters in label of electrical control cabinet, the method of automatic computer numercial control (CNC) programming based on Edgecam software was proposed. The ideas for systematically architectural generating based on Edgecam was proposed, the key technologies of manufacturing information extraction of DXF, generation of characters in single line style and automatic programming method were studied. The program was written in using VB.NET combined with PCI, PDI and other secondary development languages in Edgecam as a platform, the case programming used in a typical part proves validity of the proposed method. Intelligently and rapidly programming and machining of label of electrical control cabinet are implemented, which provides reference for the programming intelligently and rapidly in other product of CNC machining.
