Abstract: To improve quality and efficiency of Numerical Control（NC）programming by reusability of NC programming, a dynamic decomposition strategy based on cutting tool machining feature was proposed. According to product characteristics and available manufacturing resource, feature was classified and managed by machining equipment. Machining feature base was constructed to realize parametric and modular feature-based NC programming generation. Different to existing feature modeling methods, this feature model included not only geometric information of the features, it also defined NC program generation modules such as cutting-tool selection, path optimization and parameter-driven. The proposed method greatly improved NC programming time, inheritance and reusability of NC codes.
