Abstract: Aiming at reducing the difficulty of the traditional conjugate cam profile design, improving the accuracy, shortening the design cycle, saving the cost and realizing the parametric design of the cam mechanism, the Visual Studio. NET development tools was used to re develop the Auto CAD software in Visual C#. Combined with the principle of cam design, the appropriate application was designed and parameters were input in the interface through the human computer interaction,the point coordinates of the cam theory contour were obtained. According to the offset algorithm, the corresponding coordinates of the actual contour of the cam were obtained.Using the cubic B spline interpolation algorithm, the complete theoretical contour and the actual contour line were completed.Finally,an instance validation and SolidWorks motion simulation were performed. The results indicate that the method of using the Visual Studio. NET development tool to find the cam profile curve in the secondary development of Auto CAD can realize the parametric design of the conjugate cam mechanism under the premise of ensuring the accuracy and efficiency of the conjugate cam design.

Key words: Visual C#; Auto CAD re development; conjugate cam; motion simulation
