This paper proposes CAD data integrated machining system for realizing advanced machining which is feature-based and machine independent. STEP-NC remedies the shortcomings of current NC data and is basic data structure for realizing the advanced machining system. To realize STEP'NC based manufacturing systems, it is necessary to perform machining feature extraction and data complementing of machine specific parameters. In this paper, a method to assist manufacturing feature extraction is proposed, which extracted an area of a product corresponding to a manufacturing feature based on the cutting tool approach direction. For data complementing of machine specific parameters, value setting method is also proposed. This method sets a default value of optional attribute using EXPRESS-X.
