Geometrical product specifications (GPS) - Acceptance and reverification tests for coordinate measuring machines (CMM) - Part 5: CMMs using single and multiple stylus contacting probing systems (ISO 10360-5:2010)
This part of ISO 10360 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,
- a discrete point probing mode, and
- spherical or hemispherical stylus tip(s).
It complements ISO 10360-7, which is the module for CMMs with video probing systems, and ISO 10360-2, which is universal, i.e. not probe-type specific.
NOTE It is the CMM probing performance tests which 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.
This part of ISO 10360 applies to CMMs supplied with any of the following:
a) single-stylus probing system;
b) multi-stylus probing systems with fixed multiple styli attached to a single probe (e.g. “star” stylus);
c) multiple probing systems such as those with a stylus for each of their probes;
d) systems with articulating probing;
e) stylus and probe changing systems;
f) manual (non-driven) CMMs.
This part of ISO 10360 is not applicable to non-contacting probing systems, which require different testing procedures.
The terms “multi-stylus size error”, etc., should strictly be written “combined CMM and multi-stylus probing-system size error”, etc. For convenience, the wording has been truncated.
If it is desired to isolate the probing-system performance as far as is practical, the influence of the CMM can be minimized. See Annex C for more information.
