本文件描述了根据GPS规范控制制造过程的原理和工具。为此，使用一组与制造工艺参数和根据制造基准系统建立的制造工艺坐标系相关的一个或多个互补、独立的特征（尺寸、形状、方向和位置特征相互独立）。 本文件描述了GPS规范宏观几何部分的分解概念。它不包括微观几何结构，即表面纹理。 本文件中所述分解的目的是定义制造控制的校正值或对过程进行统计分析。

This document describes principles and tools to control a manufacturing process in accordance with a GPS specification. For this purpose a set of one or more complementary, independent characteristics (size, form, orientation, and location characteristics independent to each other) that correlate to the manufacturing process parameters and to the manufacturing process coordinate system established from the manufacturing datum system are used. This document describes the concept of decomposition of the macro-geometrical part of the GPS specification. It does not cover the micro-geometry, i.e. surface texture. The objective of the decomposition presented in this document is to define correction values for manufacturing control or to perform a statistical analysis of the process.
