新一代产品几何量技术规范(GPS)标准体系研究

Research on the Next Generation Geometrical Product Specification and Verification (GPS)

新成立的国际尺寸与产品几何技术委员会(ISO/TC213)提出了新一代GPS标准体系,该标准体系由基础、全局、通用和补充GPS标准组成。新一代GPS标准为产品的设计、制造、检验与评估提供了一套完整的技术规范。分析了新一代产品几何量技术规范(GPS)的系统模型、标准体系、关键技术、目前的研究方向与内容,以及我国新一代GPS标准体系的建立途径。

ISO/TC213 on GPS has been working towards harmonizing previously standardized practices in tolerancing and related metrology, and published the next generation of the GPS language now. The masterplan structure of the improved GPS system is constructed with a matrix model, which includes four kinds of GPS standards, fundamental, global, general and complement GPS standards. ISO/TC213 will offer the full technical specifications of the product designing, manufacturing, verification and evaluation, which are based on simplicity and minimization of total cost. In this paper, we analyzed the matrix model of the improved GPS standards, and presented the rules of preparing standards, key technologies as well as the research subjects on the new GPS.
