Mini-CAD 3-D Modellings of Multistage Shaftson the Basis of the T-FLEX CAD 3D System
Abstract:
A system for semi-automatic design of 3D models of machine-building parts of the 'body of revolution' type - multi-stage shafts, made on the basis of the domestic software complex of threedimensional solid modeling T-Flex CAD 3D, is being considered. Such systems can be classified as mini-CAD. This mini CAD provides automatic formation of 3D models of multi-stage shafts, the design of which can include up to seven stages, grooves for the exit of the grinding wheel, chamfers and key grooves. The principles of forming a 3D model of a complex multi-stage part, its system of parameters, and features of geometric constructions are described. This model includes the entire possible set of structural elements, while the 3D model of a specific design of the shaft is implemented by excluding unnecessary steps and structural elements from this model and assigning specific dimensional parameters to the remaining elements. To simplify the process of entering a description of a specific version of the shaft, a user interface is introduced in the mini-CAD.
