To satisfy the manufacturing requirement of tyre tread pattern mold, the problem of machining region planning in the computer aided manufacturing of tyre mold is introduced. And it is analyzed that the core technology is the definition of inner and outer contours for machining region planning and tool-path planning. According to the defect of traditional constructed way of machining region, an auto recognition method of inner and outer contour is studied based on the inclusive test method.The detail step of the method is illustrated.Thinking about the special condition of the method, corresponding strategy is given. This method is applied in the computer aided manufactuing of tyre tread mold, by which machining region planning can be solved effectively.
