| Summary: | Currently, the design of cam emphasizes on producing the surface of cam’ s profile used for kinematics analysis, while lacking in the reconstruction of the whole geometric model of cam. A method of reconstructing geometric model from cam object is proposed, thus the CAD model is produced through feature analysis, measuring with CMM, data processing, feature fitting and blending. The method is based on cam features and the reconstructing model is oriented toward not only design but also manufacturing with wide applications. The implementation of the method is illustrated by an example of a disc cam. |
