In order to improve the application level of bevel gear tooth face inspection technology and effectively increase the processing precision and the meshing quality of the small module gear

the test and application of tooth surface accuracy and processing quality are analyzed based on one dimensional probe by means of the tooth surface structure characteristics and the measurement theory of small module bevel gear.Furthermore

the need for the tooth surface quality inspection in the digital manufacture of small module bevel gear was elaborated via the application methods of the measurement technique in the production practice.
