Study of the Intelligent Turning Machining Method Based on Geometrical Feature Recognition

摘要

Feature recognition is a key technology of the automatic intelligent turning machining method. This paper provides an intelligent turning machining method based on geometrical feature recognition, including putting up viewpoint, direction and cylindrical co-ordinate. For real-loops and unreal-loops in projection, an algorithm is taken forward to recognize the straight faces, turning circle (cone, frustum and cylinder) and slot, and creates a relationship functions among all the loops, determine the machinable turning cutting regions respectively according to the relationship functions. The study resolves the machinable problem in design stage, a method is supported to cooperative design and decreases the cost and save time, a hierarchy architecture of the center controller is constructed including integration process planning.
