Computer Numerical Control (CNC) is a method used to automate the control of machine tools using software embedded in a microcomputer attached to the tool.
The CNC controller works together with a series of motors and drive components to move and control the machine axes, executing the programmed motions. On the industrial machines there is usually a sophisticated feedback system that constantly monitors and adjusts the cutter’s speed and position.
Computer aided manufacturing typically uses software to translate drawings and data into detailed instructions that can drive some sort of automated tool. As an example, a 2D digital drawing can be used to guide a laser or physical cutting tool to cut cladding or other components to fit an architect’s design.
In these images, the CNC is used by our members for the production of one of our project, RA, an UAV entirely powered with solar panels:
