Abstract

Ever since che introduetion of commercially avallable computer-aided design (CAD) and computer-atded manufaecuring (CAM) syatems, Che need for an lncerface between the two Systems has become appareni Despite efforcs by several Software companies and che American National Standards Institute (ANSI), most vendors of CAD/CAM have not made their softwares compatible wich graphics Standards. It is extremely essential to have a Single recognized strueture for communicacion of data between CAD/CAM Systems.

The Initial Graphics Exchange Specification (IGES), managed by che National Bureau of Standards (NBS), established the initial base für direct digital exchange of graphics data. The IGES is a communication file structure for data praduced on and used by CAD/CAM Systems.

The purpose of this paper ie to define and develop a data Interface between CAD and CAM Software packages using IGES file structure. The Interface will be achieved by (1) the establishment of the Standard procedure for processing the IGES file, (2) the definition of the Standard data base for the storage of the data in the IGES file, and (3) the generation of the communication Eile for the CAM Software.
