16、cal Product Specifications (GPS)- Acceptance and reverification tests for coordinate measuring machines (CMM)- Part 2 : CMMs used for measuring size Introduction This Japanese Industrial Standard has been prepared based on the first edition of IS0 10360-2 Geometrical Product Specifications (GPS)-Acc
17、eptance and reverification tests for coordinate measuring machines (CMM)-Part 2 : CMMs used for measuring size published in 2001 without modifying the technical contents. The portions of this Standard shown by dotted underlines are the matters not sated in the corresponding International Standard. T
18、his Standard is a geometrical product specification (GPS) standard and is to be regarded as a general GPS standard (see TR B 0007). It influences link 5 of the chains of standards on size, distance, radius, angle, form, orientation, location, run- out and datums. For more detailed information of the
19、 relation of this Standard to other standards and the GPS matrix model see annex B. The tests of this Standard has two differential technical objectives, which are to test - the error of indication for size measurement, and - the probing error, of which the more important is the test for the error o
20、f indication for size measure- ment. The benefit of this test is that the measured result has a direct traceability to the unit length, the metre, and that it gives knowledge on how the CMM will perform when similar measurement relative to the unit length is performed. The ot2ier test is intended to
21、 assess the 3D-probing error as a supplement to the test for the error of indication for size measurement, which only involves the prob- ing system in two dimensions. Because it is not possible to completely isolate the probing errors from other sources of machine error, some measurement errors, of
22、both static and dynamic origin, inherent in the other parts of the CMM measuring system, will affect the results of measurement in this test. 1 Scope This Standard specifies the acceptance test for verifying that the perfor- mance of a CMM used for measuring size is as stated by the manufacturer. It
23、 also specifies the reverification test which enables the user to periodically reverify the performance of a CMM used for measuring size. The acceptance and reverification tests of - probing error, and - error of indication for size measurement, given in this Standard, are applicable only to CMMs us
24、ing contacting probing sys- tems of any type operating in the discrete-point probing mode.

36、he case of reverification tests. The error of indication of a CMM for size measurement, E, and the maximum permissible error of indication of a CMM for size measurement, MPEE, are expressed in micrometres. 4.2 Probing error The probing error, P, shall not exceed the maximum permis- sible probing err
37、or, MPEp, as stated by the manufacturer, in the case of acceptance tests the use, in the case of reverification tests. The probing error, P, and the maximum permissible probing error, MPEp, are expressed in micrometres. 4.3 Environmental conditions Limits to be respected for permissible environ- men
38、tal conditions such as temperature conditions, air humidity and vibration at the site of installation that influence the measurements shall be specified by the manu- facturer, in the case of acceptance tests the user, in the case of reverification tests. In both cases, the user is free to choose the
39、 conditions within the specified limits. 4.4 The limits of the probing system configuration (stylus, sty- lus extensions, stylus orientation, weight of stylus system etc.) to which the stated value or values of MPEE apply shall be specified by the manufacturer, in the case of acceptance test the use
40、r, in case of reverification tests. In both cases, the user is free to choose the way in which the components of the probing system are config- ured within the specified limits. The form deviation of the stylus tip will influence the measurement results and shall be taken into account when proving c
41、onformance or non-conformance with speci- fication. Probing system 4.5 Operating conditions The CMM shall be operated using the procedures given in the manufacturers operating manual when conducting the tests given in clause 5. Specific areas in the manufacturers manual to be adhered to are, for exa
42、mple, a) machine start-up/warm-up cycles, b) stylus system configuration, c) d) probing system qualification. cleaning procedures for stylus tip and reference sphere, and NOTE : The stylus tip and the reference sphere should be cleaned before the probing system qualification in order to eliminate an

45、ons and the manufacturers procedures. 5.2 Probing error 5.2.1 Principle The principle of the assessment method for the probing error is to establish whether the CMM is capable of measuring within the stated maximum permissible probing error, MPEp, by determining the range of distances of the mea- su

The reference sphere supplied with the CMM for probing system qualification pur- poses shall not be used for this test.
47、The form of the test sphere shall be calibrated? since the form deviation influ- ences the test result, and shall be taken into account when proving conformance or non-conformance with the specification. The test sphere shall be placed at a location other than that of the reference sphere used for t
