Processing technology of face gear complex surface based on bus control

A control method for five-axle linkage CNC machine tools was proposed based on EtherCAT, and special CNC processing equipment for face gear was developed. The principles and methods of hopping and milling were analyzed on the basis of the principle of face gear cutting. The CNC processing coordinate conversion and tool path generation of hopping and milling were conducted. The CNC methods of processing were given based on the structure of the special face gear machine, and processing experiments of face gear were conducted. The coordinate values of tooth surface points were detected by pmm-c700 CMM, and the deviation ranges in the normal direction of face gear surface were obtained. The results verify that the structure of the machine and the processing methods are feasible, which lay the foundation of engineering applications of face gears.
