You talking about a machine to make gears? Simple, hobbing is no different than thread cutting on a lathe. It is a form of indexed machining.

CNC utilizes dimensional control.

Two are completely different terms. You could have a CNC controlled hobbing machine...

CNC means Computer Numerical Control. Basically this means a computer controls machine movement based on numbers input into the system.

Hobbing machines typically make gears. They can be mechanically actuated or electrically controlled.

Great site, thanks! I'm actually in the business of providing funding for machinery but I want to know more about the industry so I can make sure I'm acting in the client's interest when I make recommendations.

I thought this was going to be about Frodo and Samwise
