在漂移模型、虚拟边界要求、条件公差理论以及ＩＳＯ 和国家标准的公差原则基础上，给出可用于孔轴类零件公差一致性验证的软件量规数学等效式。为基于约束的参数化ＣＡＤ系统中，计算机辅助公差设计的评价提供了理论依据，对促进ＣＡＤ／ＣＡＭ 集成，特别是并行工程的发展具有重要的科学意义和应用价值
Based on the drift model, virtual boundary requirement, the theory of conditional tolerance and the tolerance principle of ISO and national standards, the mathematical gauge equivalent of software gauge which can be used to verify the tolerance of hole parts is given. It provides a theoretical basis for the evaluation of computer-aided tolerance design for constraint-based parametric CAD system and has important scientific significance and application value for promoting CAD / CAM integration, especially for parallel engineering
