Abstract

This section specifies the allowable deviations for the positioning accuracy test of the linear axis and rotary axis of precision machining centers. This section applies to precision machining centers with a linear axis travel of up to 2,000 mm and a rotary axis travel of up to 360°. Precision machining centers with a linear axis travel greater than 2,000 mm can also be used as a reference for this test.
