Annex A (informative) Bibliography

Defines the tests for assessment of the repeatability of positioning of individual pallets, together with the total accuracy of positioning of a batch of pallets associated with a specified machine. (Ref. ISO 230 pt1, ISO 230 pt2).

This part of ISO 10791 specifies, with reference to ISO 230-1 and ISO 230-2, the tests intended to assess the repeatability of positioning of individual pallets and the total accuracy of positioning of a batch of pallets associated with a specific machine.

In a manufacturing system the accuracy of positioning of a workpiece or a work-holding fixture depends on the fitting between pallets and receivers. It should be noted that this part of ISO 10791 applies to a single machining centre, i.e. to the single receiver, with multiple pallets.

The results of the tests considered here could be extended to the whole manufacturing system only if the measuring instruments were placed on the different machines exactly in the same position with respect to the origins of the linear axes. This, in practice, is difficult and inaccurate, because origins of the linear axis are affected by the repeatability of the axes.
