STEP AP213 Coverage Analysis

Published

Author(s)

Shaw C. Feng, Lihong Qiao

Abstract

This report provides a quantitative coverage analysis of a draft Application Protocol (AP) for numerically controlled machining process plans in an international standard for product data representation and exchange. The analysis addresses the effectiveness of this AP by analyzing the coverage of the data model in the AP to the interface data from several commercial computer-aided process planning systems and numerical control programming systems. It is necessary to evaluate how much machining process information can be unambiguously exchanged among commercial systems in order to determine if the AP should proceed through the standards process as is or if there should be further changes. The report documents several measurement techniques, describes meassurement results, and reveals some limitations found in the AP.
