Overview

EN ISO 2538-1:2014 - Geometrical product specifications (GPS) - Wedges - Part 1: Series of angles and slopes (ISO 2538-1:2014) defines the basic terms, nominal values and calculated parameters for wedges used in mechanical engineering. This GPS general standard specifies three series of wedge angles (from 120° down to 0° 30′) and a series of wedge slopes (from 1:10 to 1:500). It establishes clear definitions for wedge-related features (wedge, wedge angle β, wedge slope S, rate of wedge C, wedge edge) and provides tabulated nominal and calculated values (angles, slopes, rates) to be used for design, tooling and metrology.

Key topics

• Definitions and notation: precise terms (wedge, wedge angle, wedge slope, wedge edge, rate of wedge) to ensure consistent specification and inspection.
• Series of nominal values: three angle series including standard and special wedge angles; slope series covering common engineering gradients (1:10 … 1:500).
• Calculated parameters: conversion between angle, slope and rate of wedge (C = 2 · tan(β/2)), and tabulated calculated values to support measurement and production.
• Order of preference: angle series 1 and 2 are to be used in a preferred order to reduce the variety of tools, gauges and measuring instruments needed.
• GPS context: positioned as a general GPS standard influencing chain links 1 and 2 in the GPS matrix (angle). ISO 8015 and decision rules in ISO 14253-1 apply to specifications made using this standard.
• Informative annex: relation to the GPS matrix model and links to complementary standards.

Applications

EN ISO 2538-1:2014 is practical for:

• Specifying wedge features on fixtures and tooling (e.g., vee-blocks, dovetails, gauges).
• Design and selection of standard wedge angles and slopes for jigs, fixtures, mating parts and calibration artefacts.
• Metrology and inspection planning where consistent angle/slope definitions and conversion values are required.
• Reducing tooling inventory by choosing preferred angle series to harmonize production and measurement equipment.

Who uses this standard

• Mechanical and fixture designers
• Metrology and quality control engineers
• Tooling and gauge manufacturers
• Calibration laboratories and standards bodies
• CNC/machining shops specifying mating angles and slopes

Related standards

• ISO 2538-2 - Dimensioning and tolerancing (complements Part 1)
• ISO 8015 - GPS fundamentals
• ISO 14253-1 - Decision rules for conformity by measurement
• ISO/TR 14638 - GPS Masterplan

Keywords: EN ISO 2538-1:2014, ISO 2538-1:2014, wedge angles, wedge slopes, geometrical product specifications, GPS, vee-block, dovetail, rate of wedge.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. Th
