| Summary: | Computer aided design (CAD) is the earliest stage of the product cycle in a computerised manufacturing environment. CAD has the greatest role in helping to visualise the initial concept of a design with presenting the idea in a graphical view. The advanced of digital computer has eased the work of design drawing with generating the most complete design in 2D (two dimensional) and 3D (three dimensional) views. The generated drawing from CAD is not the end of the cycle of the product manufacturing process. The selected drawing will be sent to the manufacturing department for manufacturing process. The drawing created by CAD is just the description of geometrical features of the design component. This type of data cannot be used directly for the manufacturing process and normally intervention of human effort is needed to define all the manufacturing features from the component drawing again. As a result, a new system and database will be proposed. This system which has the ability to extract geometrical features from drawings and identify all the manufacturing features which is useful for manufacturing process. A neutral drawing format (ISO 10303-203) is as the input of the system. Then, a mechanism which consists of manufacturing feature extraction and feature recognition will be implemented and lastly, a new form of manufacturing feature-based data, ISO 10303-224 will be acquired for the subsequent manufacturing process. |
