Model-Based Development Architecture for Embedded CNC System

Current development method for computerized numerical control ( CNC ) system is mainly based on manual programming, so it is very time-consuming and is difficult to guarantee system performance. This paper presents a model-based development architecture, which is based on meat-model and model transformation, to address the problem. A domain-specific meta-model has been created to establish a special modeling environment for CNC system. In this modeling environment, different implementation models may be constructed according to different system requirements. These models can be translated into third-party simulation tool by model translators so that they can be analyzed and validated. Models interpreters are used to generate source code automatically from models to produce executable system. This development architecture can promote development efficiency, reduce development cost and improve system stability.
