ABSTRACT:
A measuring arrangement suitable for checking the geometric and dynamic accuracy of two numerically controlled machine elements which are displaceable with respect to each other. A base body is fastened on a carriage of a machine tool to be tested, on which a linear guide with a linear measuring device is rotatably seated. A measuring element is fastened in a spindle of the machine tool and is connected via a guide with the carriage. The measuring element has three pivot bearings and a further linear guide, as well as further measuring devices for measuring the rotating movements around the pivot bearings and along the further linear guide. Thus the measuring arrangement has six degrees of freedom, wherein four rotary and two translatory joints make possible the registration of individual deviations.
