The In-line Gear Measuring Machine (GMM) based on the double-flank gear rolling test with many degrees of freedom was developed to inspect the gears fast in workshop. The radial composite deviations and tangential deviations can be evaluated during one inspection. To evaluate the measuring machine, the repeatability test is the most critical. Many factors should be notified in the repeatability test, such as mechanism accuracy, clearance between bore and arbor, accuracy of master gear and the gear to be inspected, spring stiffness and damping coefficient, stability of the air pressure, measuring force, starting point of measurement, speed and rotation direction of gear, clean and no stain, etc.. After taking account of the above factors, the repeatability test of GMM was implemented.
