Abstract
In this study we develop ADS that we have widely used in the CAD/CAM system to include a mechanical element automatic design program and the processing program which produces a three-dimensional model automatically. The program, which produces an automatically three-dimensional surface and solid model that has been used in CAD/CAM system, widely creates an automated two and three-dimensional model by inputting several necessaries for the design, and design element. It should be emphasized if you are just a beginner having only basic knowledge of mechanical engineering, you might be able to easily design a three-dimensional model. The processing program was made to correct the faults of the expensive CAM software and the errors to be handed down from a minute circular interpolation to a linear interpolation. The software to be used to develop ADS is VisualLISP, a developer program of AutoCAD.
