| Summary: | 碩士 === 國立中興大學 === 機械工程學系 === 88 === To manufacture a 2.5 D workpiece, using the object-oriented programming and the feature-coding based method, the object of this thesis is to develop a system for automatic generation of NC (Numerical Control) code and the system is efficient and easy to use.
According to working sequences, features are coded and the corresponding dialog boxes are poped up for inputs of feature parameters and parameters of working conditions. Then, the feature drawings are generated to examine if they match the required manufacturing features. Finally, the corresponding machining NC code is generated. During the coding process, the values of feature parameters are examined on the geometric constraints and working conditions. If there are any mistakes, the system will send signals to the user for correction. The error conditions will be eliminated.
All of the procedures are recorded in the output text file, which also shows the coding symbols and parameter values. Further examination can assure the correctness of parameter values and NC code. Also, the text file provides the source of input as basic data for further modifications. Eventually, foolproof NC code is generated as the final result.
