• Resumen

  • The design engineer requires a better tool than those currently available if he is to fulfil his role effectively in an integrated computer-aided design and computer-aided manufacturing (CAD/CAM). He needs a system that has advantages of geometric modelling that quickly respond to changes in the manufacturing engineer ideas in a complete form. This paper proposes a new approach based on the concept of engineering description for variant feature. The description is achieved by selecting, from defined models, typical component features. This research introduces three different types of variant feature models. They serve as commands for simple and compound feature creation of different shape, size and type. The first model is a through taper pocket, the second model is a through simple pocket, and the third model is a simple through hole. These models introduce flexible procedures to generate feature shapes.
