In this paper, we show that a gear-measuring machine is used for whole gear outline without detaching the stylus from a target gear surface. The proposed method is one of the non-generating methods, but the total scanning time is shorter than the time taken for a conventional method, and additional shapes including tooth root, bottom profiles, and tooth tip edge corners as well as both tooth flanks can be obtained with a single scanning measurement. In this paper, a basic strategy for measuring tooth tip edge corners is proposed. Indeed, an edge measurement is generally difficult because the derivative is discontinuous and the normal vector cannot be found uniquely. Some issues concerning nominal data and stylus displacement are raised, and measures to improve scanning measurement are addressed.
