Overview
ISO 5968:1981 - Circular Screwing Dies - Terminology is an international standard developed by ISO/TC 29 (Small Tools) specifying terminology related to circular screwing dies. This standard provides a harmonized vocabulary that ensures clear communication among manufacturers, distributors, and users of circular screwing dies worldwide. By standardizing terms in several languages, including English, French, and Russian, and offering equivalents in German, Italian, and Dutch, ISO 5968 helps unify the international understanding of key features, types, and parts of circular screwing dies used for threading applications.
Key Topics
- Definition of Circular Screwing Dies: Provides precise terminology for types, forms, and features of circular dies used to cut threads.
- Die Types: Covers fixed dies, adjustable dies (with and without adjusting screws), and their variants based on adjustment mechanisms (radial or tangential).
- Parts and Features:
- Body (main structure)
- Threaded section
- Cutting edge and entry (e.g., normal face, spiral face)
- V-groove, recess, and adjusting screws
- Profile characteristics (diameter, width, radial clearance, thread length)
- Multilingual Terminology: Gives equivalent terms in six major manufacturing languages for global implementation.
- Proper Use of Terminology: Clarifies that only terms from official ISO languages are recognized for compliance and documentation.
Applications
ISO 5968 supports a wide range of practical applications by standardizing terminology for circular screwing dies:
- Manufacturing and Quality Assurance: Assists manufacturers in accurately describing and specifying die products, supporting consistent production and product quality.
- Technical Documentation and Catalogues: Streamlines creation of clear, unambiguous product catalogs, technical datasheets, and user manuals.
- International Trade and Procurement: Reduces misunderstandings in cross-border transactions by using standardized terms for product specifications and orders.
- Training and Education: Provides a reference for technical education, ensuring that students and professionals use correct vocabulary for die components and features.
- Machine Tool Industry: Facilitates communication between toolmakers, machine operators, and maintenance personnel regarding die installation, adjustment, and selection.
- Standardization and Compliance: Enables companies to align their internal documentation and processes with internationally recognized terminology, aiding compliance and audit efforts.
