A novel 3D laser ball bar (3D LBB) has been developed to determine the shaft or tool point positions rapidly and easily. The design of this instrument is discussed and the error contributors are sought to determine its accuracy. As one kind of applications, the 3D LBB is used to test the volumetric error of a parallel type machine tool. The satisfactory experiments and results show the LBB is capable of 3D tool path measurements with high precision.
