A CNC (Computer Numerical Control) machine transforms digital designs into physical parts through automated control. The basic components and their roles are: Controller: The “brain” that runs the CNC. It reads G-code instructions and sends precise movement commands to ...
There are many accessories and aftermarket upgrades that improve a CNC machine’s capabilities. Key additions to consider include: Automatic tool setter: A touch probe or tool break detector quickly measures tool length and diameter. This eliminates manual measurements and ...
Choosing CAD/CAM software depends on your workflow, budget, and the complexity of parts you need to make. CAD (Computer-Aided Design) lets you model parts in 2D/3D, while CAM (Computer-Aided Manufacturing) generates toolpaths and G-code for your CNC machine. Here ...
