Abstract
In this paper, the results of the research of three-dimensional (3D) parameter modelling of different types of standard catalogue gears using CATIA V5 software system. Gears modelling by computers are based on geometric and perspective transformation which is not more detail examined in the paper because of their large scope. Parameter modelling application makes possible the control of created 3D gear model through previous defined parameter which is based on relations and geometric constraints (parallelism, perpendicular, etc.). The final shape of gear changes by changing of values of characteristic independent changeable parameters, and that makes possible model creation in short time. Obtained 3D gear model from CATIA V5 system is used as the base for technical documentation making, analysis of stress and deformation by Finite Element Method (FEM), generating of NC/CNC programs for production of the parts on machine (CAM/NC), Rapid Prototyping (RP), etc. Final taking into consideration shows that functionality of parameter associatively must obligatory apply in interaction with traditional geometric modelling approach that appears until now. Modelling methodology and functionality that is described by selected examples can be used in any category of industry and in any process.
