CNC (Computer Numerical Control) Machines
A CNC machine is a computer numerically-controlled machine that operates from a computer-generated tool-path. It is capable of cutting a range of hard materials, such as wood, foams, and plastics. The machine uses a rotating bits to remove material from a defined stock material and is capable of cutting the the X, Y, and Z directions. The machine is appropriate for cutting 1:1 scale prototype parts such as, furniture and facade panels, or smaller parts for models. The machine is a good solution for cutting curved and doubly curved surface geometry and 2-D shapes and parts.
