Aiming at the problems existing in the development of ultrasonic testing computer-aided process planning (UTCAPP), "UTCAPP based on the testing standard" was put forward, which brought the technology to not only better meet the actual needs of ultrasonic testing process design, but also greatly simplify the complexity of the problem and reduce the difficulty of development. In this paper, on the basis of in-depth study of the relationship between the ultrasonic testing standards and process planning, a UTCAPP system is developed through SQL2005 and VC++ 6.0 with artificial intelligence method for establishing the knowledge base and inference mechanisms.

ISO 14649, known as STEP-NC, is new model of data transfer between CAD/CAM systems and CNC machines. In this paper, the modeling based on machining feature is proposed. The machining feature comes from the manufacturing process considering the restriction of machining technology and machining resource. Then the framework for computer aided process planning is presented, where the algorithms of operation planning is studied. The practical example has been provided and results indicate that machining feature based model can integrate with CAPP and STEP-NC seamlessly.
