A machining and forming method of large gear based on numerical control machining was studied. The CNC forming technology of large gear machining was analyzed, a large modulus cylindrical gear was machined by numerical control machining technology with its machining accuracy of the technology being tested. The statistics indicate that the indexes of the tooth shape error and tooth direction error of the large modulus cylindrical gear are all less than the specified scope.
