摘要

公差信息在产品生命周期的许多步骤中起着至关重要的作用，由于互联网技术的进步和工业集成需求的增加，公差信息尤为重要。本文研究了制造过程中的几何公差信息，并根据ASME Y14.5-1994、STEP和DMIS标准建立了几何公差的分层一致性等级。建立了IMP中几何公差信息的EXPRESS-G数据模型。在IMP中使用XML语言对几何公差信息进行表示和编程。

A Study on Geometric Tolerances Information Modelling in Integrated Manufacturing Processes

Tolerance information plays a critical role in many steps of the product life cycle and especially important due to the advances in Internet technologies and increasing integration requirements from industry. In this paper, geometric tolerances information in manufacturing process (IMP) is studied, and the layered conformance level of geometric tolerances is established according to ASME Y14.5-1994, STEP and DMIS. An EXPRESS-G data model of geometric tolerance information in IMP is established. The XML language is used to represent and program the geometric tolerances information in IMP.
