4 Best Free and Open Source CNC Software

CNC (also known as numerical control or computer numerical control) is the automated control of machining tools (such as milling machines, lathes, 3d printers, laser cutters, plasma cutters, robot arms, hexapods) by means of a computer.

A CNC machine processes a piece of material (metal, plastic, wood, ceramic, or composite) to meet specifications by following coded programmed instructions and without a manual operator directly controlling the machining operation.

In modern CNC systems, the design of a mechanical part and its manufacturing program are highly automated. The part’s mechanical dimensions are defined using CAD software and then translated into manufacturing directives by computer-aided manufacturing (CAM) software.

This chart provides our recommendations. We only feature open source software here.
