Introduction

With the implementation of the national product quality improvement plan, the unified norms or principles used in the process of product design, manufacturing, measurement and inspection

needs are becoming more and more urgent. The surface structure representation method and related standards in the original product geometric technical specifications can no longer meet the requirements of the product manufacturing process.

Surface quality control requirements in the process.

GB/T 33523 "Product Geometric Specifications (GPS) Surface Structure Area Method" is based on the new generation of GPS product geometric specifications

Through digital measurement technology, software analysis technology and measurement evaluation, a new set of three-dimensional surface structure measurement and analysis

recommended national standards. GB/T 33523, on the basis of proposing the surface structure representation, surface structure parameters and standard operation set, analyzes

The method of surface structure measurement is given, the measurement technique used and the nominal characteristics of the instrument are given. In particular, GB/T 33523 covers contact

At the same time, it focuses on introducing a variety of non-contact measuring instruments that are of great value in high-precision measurement applications but lack standard support.

1 Scope

GB/T 33523.602-2022 describes the confocal chromatic probe, one of the optical instruments used to measure surface texture over an area rather than along a line. The principle is elegant: white light is focused through a deliberately dispersive lens, so each wavelength comes to focus at a different height, and the wavelength that returns most strongly tells the instrument how far away the surface is. There is no moving part in the measuring axis and no contact, which suits soft, sticky or finely finished surfaces that a stylus would damage or misread. Optical instruments do not measure the same thing a stylus does, though — they are affected by the material's reflectance, by steep local slopes beyond which the light does not return, and by transparent films — so a specification must state the instrument's characteristics for a measurement to be interpretable. This part specifies the nominal characteristics and design of non-contact instruments using a confocal chromatic probe based on axial dispersion. Under ICS 17.040.20 and CCS J04, it is written for metrology instrument makers, calibration laboratories, and manufacturing engineers who specify surface finish.

This document specifies the design of a non-contact instrument for the measurement of surface structure using a confocal chromatic aberration probe based on the axial dispersion properties of white light

and metering properties.
