17.040.40 - Geometrical Product Specification (GPS)

This document provides an unambiguous calculation of parameters PSm, RSm, WSm and Pc, Rc, Wc, as defined in ISO 4287, by means of a flowchart.

This document specifies the dimensional and geometrical characteristics, boundary dimensions and tolerances of insert bearings and eccentric locking collars and the radial internal clearances of insert bearings.

This document specifies the most important design and metrological characteristics of calliper
depth gauges
— with analogue indication: vernier scale or circular scale (dial); and
— with digital indication: digital display.

This document specifies biorthogonal wavelets for profiles and contains the relevant concepts. It gives
the basic terminology for biorthogonal wavelets of compact support, together with their usage.

This document specifies acceptance and periodic reverification tests of CMM performance with
contacting probing systems and is only applicable to CMMs using:
— any type of contacting probing system; and
— spherical or hemispherical stylus tip(s).
NOTE CMM probing performance tests are specified by the maximum permissible errors (MPEs), due to the
impracticality of isolating the performance of the probing system from that of the CMM, even on a small artefact
such as a test sphere.

A transition is an areal feature connecting two adjacent features, for which the intersection is a line. The transition includes portions of the adjacent features. This document defines a number of specification operators for the specification of defined transitions. These specifications all apply to any line in a defined direction in the transition feature. It also defines the specification modifiers and the drawing indications for such transition specifications.
The proportions and dimension...view more

This part of ISO 25178 deals with geometrical defects that may be present on the surfaces of material measures and calibration specimens conforming to ISO 5436-1 and ISO 25178-70. It defines classes of these geometrical defects, and defines terms for ways of responding to these defects.
This part of ISO 25178 is applicable as follows:
a) to help customers and users of material measures for surface metrology specify their nominal features (ideal geometrical properties) when purchasing them from...view more

This Standard describes principles and tools to control a manufacturing process in accordance with a GPS specification. It establishes that the result of a GPS specification, consisting of one value, is not sufficient to control a manufacturing process. For this purpose it is necessary to use a set of one or more complementary, independent characteristics that correlate to the manufacturing process parameters.
This Standard describes the concept of decomposition of the macro-geometrical part of...view more

This document describes principles and tools to control a manufacturing process in accordance with a GPS specification. For this purpose a set of one or more complementary, independent characteristics (size, form, orientation, and location characteristics independent to each other) that correlate to the manufacturing process parameters and to the manufacturing process coordinate system established from the manufacturing datum system are used.

This document specifies the metrological characteristics of areal instruments for measuring surface
topography. Because surface profiles can be extracted from surface topography images, most of the
terms defined in this document can also be applied to profiling measurements.

This document describes the influence quantities and instrument characteristics of confocal
microscopy systems for areal measurement of surface topography. Because surface profiles can be
extracted from surface topography images, the methods described in this document can be applied to
profiling measurements as well.

This document illustrates the ambiguity caused by the use of dimensional specifications to control
properties other than linear or angular size and the benefit of using geometrical specifications instead.
Dimensional tolerancing can be indicated by ± tolerancing or geometrical specifications.
The ambiguity caused by using ± tolerances for dimensions other than linear or angular sizes (for
individual tolerances and general tolerances according to, e.g. ISO 2768-1 and ISO 8062-3) is explained
