This part of ISO 10791 specifies, with reference to ISO 230-1 and ISO 230-4, certain kinematic tests for machining centres, concerning spindle speeds, feed and the accuracy of the paths described by the simultaneous movement of two or more numerically controlled (NC) linear and/or rotary axes.

This part of ISO 10791 applies to machining centres having three linear axes (X, Y, and Z) and additionally one or two rotary axes (A, B, or C). Movements other than those mentioned are considered as special features and the relevant tests are not included in this part of ISO 10791.

This part of ISO 10791 deals only with the verification of kinematic accuracy of the machine and does not apply to the testing of the machine operation, e.g. vibrations, abnormal noises, etc., which should generally be checked separately.

The tests described in this part of ISO 10791 are also applicable, totally or partially, subject to specific agreement between the manufacturer/supplier and the user, to numerically controlled milling and boring machines, when their configuration, components, and movements are compatible with the tests described herein.
