Data Exchange with Support for the Neutral Processing of Formats in Computer-Aided Design/Computer-Aided Manufacturing Systems

Abstract

This paper presents an analysis and the research results of system couplers in CAx systems that ensure the correct transfer of product data from the “supplier” system to the “recipient” system. This study presents the results of the compatibility tests between the systems based on the verification of geometric models and their attributes after importing/exporting 2D and 3D objects using neutral data exchange formats. The purpose of the research was to identify neutral formats that do not introduce errors after data transversion in certain types of geometry. Tests and analyses were carried out on selected formats depending on the type of object, such as 2D objects (DXF), solid objects (IGES, STEP, SAT, and PARASOLID), and surface objects (IGES, STEP, SAT, and X_T). One of the results of our research and analysis is the need for continuous development of CAD/CAE systems because current neutral formats are not 100% effective.
