CAD/NC INTEGRATION WITH THE OOP SUPORT

Abstract

Now days: large and small manufacturing companies own several numerically controlled (NC) iathe machines. hey are finding that NC/CNC machines can make dramatic saving possible. Certain aspects of NC/CNC shop operations require a high skilled operator level than conventional method. So that the need to develop a computerized technology to support the adoption of these machines and get the maximum benefits that's offer is highly recommended. The present work aims to develop such system that stand over the most modern available technologies to support this task. The system database is used to organize the factory data. The database hold factory lathe machines delinition at current state tooling and the available tools and materials with the recommended machining parameters for each machine-tool-material combinations. The developed system is interactive supported with a powerful graphics package (AutoCAD) which gives the system user the ability to deseribe the part manufacturing process through direct nanipulation of the part and stock in process drawing with the aid of friendly user machining process dialog box. The system offers as output different types of the product documentation files these are the process plan sheet, the computer aided plan description model, and a DXF Drawing Exchange File) format which may be used to exchange the product information between the CAD/CAM systems. Finally the system postprocessor is used to generate NC/CNC Code G-Code) Fles that are necessary to operate the predefined machines to produce the part.
