Study and Development of Graphic Automatic Programming System of Rotational Parts Based on Characteristic Technology

Aiming at the rise of workshop oriented programming (WOP), The graphic automatic programming system of rotational parts based on characteristic technology is researched and developed by using Visual C + + 6.0 as a programming tool. The character of rotational parts is extracted and classified applying characteristic technology. Geometric information and machining conditions are inputted using mutual characteristic graphic inputting instead of the traditional approach of programming language. NC codes are produces automatically. This paper introduces the working principle and function of the system, and expounds in detail the crucial technology of the graphic automatic programming system, finally, the feasibility and practicability is validated by experiment.
