CAM model parameterisation methodology and its further unification in Siemens NX environment

Abstract

The paper describes the methodology of mathematical CAD model parameterisation for the subsequent development of the control program (CP) in Siemens NX 2206, which allows in the process of changing the parametric CAD model to adapt not only the 3D model, but also to rebuild the control program, thereby significantly reducing the time for CP development. The application of methods of parametrisation of models in the article is shown in an example of simulators of blades of 3 stages. As a result, a parametric CAD model of the blade simulator, tooling for the product installation on the machine tool, for 3-axis CNC milling machining, automatically changing for each stage of the simulator were developed. A simulator manufacturing process based on the parametric model was developed and successfully implemented. The report formulated the basic provisions and rules for the design of single-type models for the subsequent development of universal control programmes for CNC machines.
