In order to obtain all individual errors which are defined in JIS, a master gear which is composed of two parts, is used for a single flank meshing test. Also, each tooth of the master gear has an effectual flank with a modified face width, which is geometrically arranged at a position in the direction of the gear axis. The experiment with the master gear was attempted for some test gears demonstrating characteristic errors. The first one has lead error and the second shows the modified curved, such as sine curve, in the meshing direction. The rest of the gears is eccentrically ground for pitch error between neighbouring teeth. Individual errors computed from the record of single flank meshing test between the master and the test gears give a good coincidence with the results from a conventional method, except for lead error.
