The digital closed-loop manufacturing technology of end face spiral gear coupling is studied
(1) The mathematical model of tooth surface considering arc cutting edge and the calculation method of theoretical tooth surface coordinate and normal vector are established.

The machine adjustment parameters and grinding wheel parameters for correcting the tooth profile error can be obtained. Through the actual grinding experiment, the maximum tooth profile error of the workpiece is corrected from 14.3 μ m to 3 μ m, which verifies the correctness of the tooth profile error correction method.

By using digital closed-loop manufacturing technology, the tooth surface precision and machining efficiency of the end face spiral gear coupling can be significantly improved.
