To apply this part of ISO 1986, reference shall be made to ISO 230-1, especially for the installation of the machine before testing, warming up of the spindle, and other moving components, description of measuring methods, and recommended uncertainty of testing equipment.
In the “Observations” block of the tests described in Clauses 5 and 6, the instructions are preceded by a reference to the corresponding Clause in ISO 230-1 in cases where the test concerned is in compliance with the specifications of that International Standard.The sequence in which the tests are presented in this part of ISO 1986 in no way defines the practical order of testing. In order to make the mounting of fixtures and machining easier, tests can be performed in any order.
When testing a machine, it is not always necessary or possible to carry out all the tests described in this part of ISO 1986. When the tests are required for acceptance purposes, it is up to the user to choose, in agreement with the supplier/manufacturer, those tests relating to the components and/or the properties of the machine which are of interest. These tests are to be clearly stated when ordering a machine. A mere reference to this part of ISO 1986 for the acceptance tests, without specifying the tests to be carried out, and without agreement on the relevant expenses, cannot be considered as binding for any contracting party.
The measuring instruments indicated in the tests described in Clause 4 are examples only. Other instruments measuring the same quantities and having the same or smaller measurement uncertainty can be used.
When the tolerance for a geometric test is established for a measuring length different from that given in this part of ISO 1986 (see 4.1 of ISO 230-1:2012), it shall be taken into consideration that the minimum value of tolerance is 0,001 mm.
Machining tests shall be made under finishing conditions only, not with roughing cuts which are liable to generate appreciable cutting forces.ISO 1986-1 pdf free download.
