Abstract

A manufacturing route is defined for any product in all of the manufacturing workshops and the factories. Since, different numbers of processes are conducted on a product, the processing routes are saved on some manual sheets. These sheets show the details of process planning for any product during the manufacturing route. By entering the computers to industry, the route sheets started to be produced using of the computers. Moreover, some software's were developed to automatically produce the process planning programs which are known as Computer Aided Process Planning (CAPP) systems. In this research, a CAPP based software is developed for feature recognition and extraction of the cylindrical parts to provide the raw data of the CAPP systems. On the other hand, except for the feature extraction of cylindrical parts, this program is be able to create the process planning program in a semiautomatic manner using of its extracted feature data. After recognition and extraction of the features, the parts are classified and are compared with the created data base features and one or more process planning program is suggested finally. Also, the new parts again can be saved for using in the program data base. This program results were compared with a different number of created process planning route sheets and the results confirmed the program reliability. Therefore, this program can be used in machining workshops with a high accuracy.
