Computer Numeric Control, more commonly known as CNC emerged during the 1940s and 50s. In its simplest form, it is the usage of a computer to create and machine a design with machine tools. CNC machines can control lathes, routers, grinders and mills[1]

The entire process is done through a computer using numeric equations and using the x, y, z axis[2]. Here, the computer can make precise cuts based on what the operator has set. Additionally it can repeat as many cuts as you would like. This makes it easy to duplicate templates than manually machining a replica. It also saves time while limiting the number of potential inaccuracies.

CNC is widely used by machinists. It is used to manufacture complex templates, fixtures and designs like crown molding. The cost of equipment is very expensive but has dropped since it has become more publicly available.[3]

CNC is incorporated into the more broad trade of tool and die making. Sheridan college offers a course included CNC programming and mechanical drafting[4]. It prepares students for careers in the machine industry. Students should have good math skills and be excellent with problem solving and reading drafts.

Typically, CNC machinists make approximately $14-30 per hour. Companies are in demand for CNC machinists as manually machining has been come less common with the emersion of CNC operated equipment. Automotive companies are constantly using CNC machines for productions of their vehicles and vehicle accessories.

If you enjoy manufacturing and computers and want to be part of a major industry in demand, give CNC machining a shot and see how rewarding this career can be!
