ISO 11090-2:2014 pdf free.Test conditions for die sinking electro-discharge machines (die sinking EDM)一Testing of the accuracy
For the application of this part of ISO 11090, 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 parts, the description of measuring methods, and recommended accuracy of testing equipment.
In the “Observations” block of the tests described in Clauses 6, 7, and 8, the instructions are preceded with reference to the corresponding clause/subclause in ISO 230-1 in cases where the test concerned is in compliance with the specifications. Tolerances are given for each geometric test (see G1 to G12).
Prior to conducting tests on a machine, the machine should be levelled according to the recommendations of the manufacturer/supplier (see ISO 230-1:2012, 6.1.2).
The sequence in which the geometric tests are given in no way defines the practical order of testing. In order to make the mounting of instruments or gauging easier, the tests can be performed in any order.
When testing a machine tool, it is not always necessary or possible to carry out all the tests given in this part of ISO 11090. When the tests are required for acceptance purposes, the choice of tests relating to the components and/or the properties of the machine of interest is at the discretion of the user, in agreement with the manufacturer/supplier. The tests to be used are to be clearly stated when ordering a machine tool. A mere reference to this part of ISO 11090 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 parties.
The measuring instruments indicated in the tests described in the following clauses are examples only. Other instruments measuring the same quantities and having the same or smaller measurement uncertainty can be used.
When built-in software facilities are available for compensating geometric, positioning, contouring,and/or thermal deviations, their use during these tests shall be based on agreement between the manufacturer/supplier and the user with due consideration to the machine tool intended use.ISO 11090-2 pdf download.
