Hello, I would like to ask if there is a future in learning hand gear shaping, how to compare it with CNC gear hobbing, and which is easier, gear machining or CNC turning?

Since they are all in the machinery industry, it is not easy. As for what you said is promising, it should be said that numerical control is better. Gear processing will be exposed to cutting fluid all day, and the smell is not very good, but you don't have to work when you look at a good gear. CNC lathe is more troublesome to process, and it needs to be sharpened frequently, but the treatment of CNC is better. Generally speaking, the difference is not very big, depending on your idea.
