The purpose of this paper is to describe a new Graphical User Interface (GUI) for Design and Computer Aided Manufacturing (CAD/CAM) applications for academic context uses. This application,created by the autor of this paper, is developed for automatic generation of Computer Numerical Control (CNC) code of two dimensional drawing created in the comercial software Autocad and using the Visual Basic programming language. In production environments, the machining of complex parts such as molds and die cast that requires high production rates and quality are tested before they are manufactured using CAD/CAM applications, where numerical control is coded automatically and is transmitted to the milling machine. These applications are characterized by high accuracy. The intuitive GUI proposed in this work is an easy to use interface that transforms two dimensional drawing saved in the proprietary AutoCAD file converextention DXF into a file format that can be used directly in a Fanuc control installed in a Benchman milling CNC machine.
