CNC

If a dragster was drawn in a CAD program, then there is the option to build the car not by hand but by computer numerical control (CNC) milling.

If this kind of equipment is available in your school or community (and you might be surprised that some companies are willing to let schools use their equipment from time to time), you can build a precise and symmetrical dragster with ease. Milling is the process of using rotary cutters to remove material from a piece (such as a dragster body blank). CNC milling is done by a computer-programmed mill to remove the material as specified by a computer-drawn design. It is almost the opposite process as 3-D printing. Most mills use the three-axis system (Cartesian coordinates).
