Abstract: A measurement method of  threeaxis turntable’s axis intersecting degree is described. The measurement method is the use of laser tracker to measure the turntable, the two fixed points on the frame (the target mirror seat position) around the rotation axis of movement of some of the space coordinates of the point where the fit of these points to construct two circles and its center, and then construct a circle by the two rotary axes. Thus, the rotation axis of the threeaxis turntable constructed after three rotary as can be calculated the distance between each, according to three rotary as the distance between any two threeaxis can be calculated intersection degree of threeaxis turntable.
