Abstract
An apparatus for measuring three-dimensional volumetric errors in a multiaxis machine tool is disclosed. The apparatus comprises a kinematic ball bar provided with two balls at both ends thereof as a basic construction. A U-shaped bar with two extension arms is integrated with the ball bar. A vertical post is positioned relative to the U-shaped bar and is integrated with one of the two balls. A sleeve is fitted over the post and two guide bars is fixedly and longitudinally assembled with an external surface of the sleeve at opposite positions. Each of the guide bars is provided with a slot at a lower portion thereof for movably receiving an operating pin.
