Based on the theory of multi-body system and gear meshing
according to the sixaxis linkage gear grinding machine with the actual conditions of grinding
the tooth surface error equation of six-axis linkage gear grinding machine is established.The contrast analysis of the simulation results with the measured error of face gear tooth surface deviation is carried out
and the two error trends are basically identical.This work provides theory basis of tooth surface error correction of face gear and error compensation of numerical control grinding to improve the machining precision.
