Is the job of a gear hobbing apprentice tiring?

The job of a gear hobbing apprentice is tiring. It takes a long time to process gears with a hobbing machine. During mass production, one operator is responsible for several hobbing machines. There is also a dedicated person responsible for adjusting the machine tool and related technical calculations. It is not difficult, but it is a bit tiring. Gear hobbing is based on the generation method principle to process gears. Using a hob to process the opposite wheel is equivalent to the meshing of a helical cylindrical gear pair.
