Abstract: Aiming at the long cycle and low efficiency of drawing software in the process of drawing the twodimensional map of the cam mechanism, the secondary development of AutoCAD software was related to the study. The disc groove cam mechanism was taken as an example and Visual Studio 2015 was used. AutoCAD was redeveloped by Visual C# language, combined with the principle of the cam design, the relevant Parameters were input in the Visual C# manmachine interface. The drawing of disc grooved cam has been completed. Finally, using SolidWorks software, threedimension modeling and motion simulation analysis of the twodimensional map of disk grooved cam with the modified sinusoidal main motion curve were performed.The results indicate that the method of obtaining the cam profile curve by using Visual C# to perform secondary development of AutoCAD software is feasible, it can realize the parameterization of the disc groove cam under the premise of ensuring the accuracy of the cam profile curve of the disc groove and shortening the drawing cycle.
