Abstract: The meshing theory of real tooth surface with error and heat treating deformation is studied systematically. A set of theory and method for analyzing real tooth surface meshing is put forward to adapt to different types of gears, and it is tested and verified by experiments. This system is practically valuable for gear precision appraisal and compensation of machining error, heat treating deformation and error of standard gear used for measurement.
