GB/T 40810.1-2021Geometrical product specifications (GPS)—Online measurement in process—Part 1:Online verification of geometric features (size and surface texture) (English PDF)

Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1: Structure and Drafting Rules of Standardization Documents" Drafting.

This document is the first part of GB/T 40810 "Geometric Technical Specifications for Products (GPS) Online Measurement of Production Processes". GB/T 40810 The following parts have been released.

---Part 1: On-line detection and verification of geometric features (size, surface structure);

---Part 2: On-line detection and verification of geometric features (shape and position).

Introduction

In the production process, the digital measurement and control method for the geometric accuracy of the product size, shape, direction, position, etc. is imperfect, and the geometric accuracy is counted.

Key issues such as the lack of characterization inspection methods and measurement uncertainty evaluation methods, and the passive backwardness of process quality accuracy measurement and control methods.

The digital measurement theory, method and technology of product geometric accuracy, and build a geometric accuracy inspection operation specification system and control system in line with the new generation of GPS. System strategy.

GB/T 40810 is based on a new generation of GPS product geometric specification system, using digital online measurement technology, statistical learning and analysis theory Theory, advanced manufacturing technology, system integration and management technology, etc., carried out by means of theoretical analysis, model mapping, and simulation/experimental verification Recommended national standards for online measurement of the production process. Focus on solving the systemicity, completeness, and uniformity of online geometric feature inspection standards and specifications One-of-a-kind issues have laid the necessary technology for effectively solving the digitization, automation and intelligence problems of geometric feature detection and control in the production process. The basis of surgery.

GB/T 40810 is mainly used to standardize the detection and verification strategies and methods of geometric features in the production process, and provides Online/offline) The digital operation method and testing specification of product quality accuracy measurement. For the convenience of readers, the standard is divided into two parts When compiling, the two parts are related to each other and independent of each other, which together constitute the content of the online detection and verification specification for geometric features.

GB/T 40810 consists of two parts.

---Part 1: On-line detection and verification of geometric features (size, surface structure). Specifies the geometric characteristics (dimensions, Specification for online inspection and verification of surface structure). Describes GPS-based online feature extraction, filtering (surface error separation), Methods of fitting, evaluation, eligibility judgment, and default operating specifications.

---Part 2: On-line detection and verification of geometric features (shape and position). Specifies the geometric characteristics (shape and position) during the production process Online testing and verification requirements. Describes the online inspection operation of shape and position feature and the conformity assessment rules.

1 Scope
