ISO STANDARDS FOR GEOMETRICAL FILTERS

摘要

For the past four years, a group of international experts in the International Organization for Standardization (ISO) has been working on a series of standards for geometrical filters. This effort was motivated by an urgent need in industry to define the terms, concepts, and techniques involved in reducing raw data collected by measurements for proper interpretation while inspecting manufactured parts to verify whether they meet their tolerance specifications. This paper describes the efforts of this ISO group and what has been accomplished thus far.
