ISO 230-1-2012 pdf free download.Test code for machine tools – Part 1: Geometric accuracy of machines operating under no-load or quasi-static conditions.
This part of ISO 230 specifies methods for testing the accuracy of machine tools, operating either under no-load or under quasi-static conditions, by means of geometric and machining tests. The methods can also be applied to other types of industrial machines.
This part of ISO 230 covers power-driven machines, which can be used for machining metal, wood, etc., by the removal of chips or swan material or by plastic deformation. It does not cover power-driven portable hand tools.
This part of ISO 230 relates to the testing of geometric accuracy. It is not applicable to the operational testing of the machine tool (vibrations, stick-slip motion of components, etc.) or to the checking of characteristics (speeds, feeds).
This part of ISO 230 does not cover the geometric accuracy of high-speed machine motions where machining forces are typically smaller than acceleration forces.

3 Terms and definitions
3.1 General
For the purposes of this document, the terms and definitions given in ISO 230-2, ISO 2304, ISO 230-7, ISO 841, ISO 12181-1, ISO 12780-1 and ISO 12781-1 and the following apply.
This part of ISO 230 uses metrological definitions, which take into account actual motions, real lines and surfaces accessible to measurement taking into account the limitations introduced by the construction or the practicality of geometric verification.
NOTE 1 In some cases, geometric definitions (definitions of run-out. etc.) have been retained in this part of ISO 230. in order to eliminate any confusion and to clarify the language used, However, when describing test methods, measuring instruments and to’erances. metrological definitions are taken as the basis.
