The objective of this study is the development of a flexible Gear Measuring Machine (GMM) which can measure cylindrical gears including working flanks, tooth root and bottom profiles as well as tip edge profiles in various patterns by installing a 3D scanning probe. In this presentation, scanning measurement of a helical gear outline is proposed without detaching the stylus tip from the gear surface. The stylus offset due to the helix angle of a helical gear is analyzed. The strategy for scanning measurement in a cross section is proposed and actual measurement is conducted. Compensated stylus contact paths are analyzed and evaluated by comparing to the corresponding ideal paths. By using the pre-measured discrete points, the deviations of the stylus tip along axial direction are minimized and profile measurement in a single cross sectional plane is achieved.
