Abstract: A five-axis space precision measurement fixture includes a body, screw holes to install first balls and second balls. The body has a first surface, a second surface, a third surface and an inclined surface located with respect to the third surface between the first surface and the second surface. The first surface and the second surface are parallel to each other and are located on opposite sides of the third surface. An included angle between the inclined surface and the third surface is 45 degree. The first balls are equal-spacing into columns and rows on the first surface, and each of the first balls is protruded from the first surface along a first direction. The second balls are also equal-spacing disposed on the inclined surface, and each of the second balls is protruded from the inclined surface along a second direction which is vertical to the first direction.
