A recently granted patent (Publication Number: US11904396B2) discloses a method for machining rotatable toothed workpieces with multiple teeth and tooth slots. The method involves loading a workpiece onto a spindle, determining a machining position based on stock-dividing, adjusting the workpiece rotationally, machining the teeth, and removing the workpiece from the spindle. Subsequent workpieces with the same design do not require stock-dividing, streamlining the process for efficiency.

Furthermore, the patent details the use of pallets with locating elements to fix the rotational position of the workpieces before loading them onto the spindle. A workholding mechanism, such as a chuck, maintains the rotational position during transportation. The method also includes the use of robots for transporting the workpieces, with chucks positioned on the robot for efficient handling. The toothed workpieces mentioned in the patent include bevel pinion gears and bevel ring gears, and the machining process is carried out using a gear grinding machine. These innovative methods and systems aim to enhance the efficiency and accuracy of machining toothed workpieces in industrial settings.
