Introduction

In order to better align the product geometric technical specification standards of molded parts dimensions and geometric tolerances in my country with the latest ISO GPS, To make various industries and enterprises of my country's molded parts more competitive in the international market, SAC/TC240 plans to formulate GB/T 6414 "Product Geometry Technical Specification (GPS) Dimensional and Geometric Tolerances for Molded Parts". GB/T 42124.1 is intended to be composed of 4 parts, each of which is interrelated and independent, which together constitute the size and geometry of molded parts. The content of the tolerance. --- Part 1.Vocabulary. It is intended to define the terms and conditions associated with describing features, shapes and tolerance types when tolerances are given definition. --- Part 2.Rules. It aims to give the geometric tolerance marking rules of the final molded parts and molded parts after machining. --- Part 3.General dimensional tolerances, geometric tolerances and machining allowances of castings. intended to specify the general Dimensional and geometric tolerances, and machining allowance levels. --- Part 4.General tolerances of castings marked with profile tolerances relative to the general datum system. designed to give relative to the final The general datum system retained on the workpiece, the method of marking the general geometric tolerances of castings using profile tolerances. return Designed to specify the machining allowances and drafts of castings formed by all casting metals and their alloys by various manufacturing processes slope.
