Design of Combined Cam Used in the New Jacquard Device Based on PROE and AutoCAD

The key point of the design of combinatory cam is the design of vice-cam contour curve. A series of dots on the follower’s path curve which driven by the unknown vice-cam were achieved by using the PROE’s curve modeling capabilities and motion simulation function. Then import these points into the curve fitting capabilities function of AutoCAD and a certain extent smooth curve that stringing every point were obtained. Finally, the curve we got from the last step was imported back into PROE, and the unknown vice- cam can be deduced.
