An Approach to Design a Globoid CAM Using CREO Parametric 3.0

Abstract

Globoid CAM surface has 3D complicated profiles, so design is quite difficult. There were several applied researches on using Matlab or API in the Catia/ProE environment to solve the curved equation. The coordinates of the surface points are computed to build CAM profiles. These methods require the designer needs to have knowledge of Matlab programming, VC,... which has not been widely used in practice. In this paper, a Globoid CAM design method has been proposed using the features of CREO Parametric 3.0 software. The motion and geometry parameters, and 3D-CAM profiles will be directly computed on the software as a parametric geometry. The computation will provide needed data to build a 3D model of CAM completion. A system of formulas and specific procedure were expressed and presented to help the designers with knowledge of CREO Parametric 3.0 designing 3D-CAM quickly, quality and suitable costs.
