Explanation of Machining Prospectus Specification: ISO, GB, ASME, GLOBAL Manufacturing Consistency Ensured?

working (of machinery)Prospectus standards are the world's common language for quality. This catalogue describes how ISO, GB, ASME, and other centres and specifications ensure worldwide interchangeability and reliability of parts, and how tolerances on dimensions, shape, position, and surface finish are specified.

Processing Standards: The Foundation Stone of Globalised Manufacturing in the World

We would like to introduce the importance of specifications in the world of production of one part in several places in the world. Specifications are also important in modern, large-scale co-production.

I. Is the basis of funk important?

(Interchangeability, consistency of quality, common efficiency, trade facilitation)

II. Introduction to the Coa Processing Prospectus Standard System

1. International specifications: ISO systems (e.g. ISO2768 general tolerances)

2. Chinese national standard: GB system (ISO compatible)

3. Rice specification: ASME Y14.5 など.

4. Industry and Community Benchmarks

III. Objectives for benchmarking and content differentiation of the CNAs

1. Inch Tolerance and Fitting System (ベースホール・シートム/ベースシャフト・シートム)

2. Geometric tolerances (shape and positional tolerances) notation and meaning of クイックチェック

3. Notation and evaluation of surface roughness parameter (Ra, Rz)

4. Specifications on Labelling of Drawings

For the fourth, the ground treatment criteria are shown on the chart.

(Float: Customer drawing labelling standard → Entertainment is standardised → Programming and Prospectus Setting → Opalescence is implemented → QC is standardised → QC is inspected).

Conclusion and CTA: The standard is a framework for changing the details of the processing programme inherent in each note. For more information on how to make specific requests, please read the next note (Link to Note 4).

YOKUARU QUESTION

"Where are the tolerances recorded on the drawings? (A: Normally, ISO2768-mK is the same as the general tolerance specification.)

"What is the biggest discrepancy between アメリカンスタンダード and ナショナルスタンダードの図面、図面を読むとき?" (Answer: The perspective projection method is not in line with the general rule that an Amalgamated Stainer is the 3rd projection, while a Nasional Stainer is the 1st projection, and it is necessary to confirm this when the diagrams are viewed).
