WHAT TYPE OF FILE FORMAT IS USED TO LOAD A DESIGN INTO A CNC ROUTER?
The modern computer-controlled routers, also known as CNC (Control Numérico Computarizado) machines, move with high precision while operating thanks to commands received through a digital file that contains precise instructions on how to process the material (such as cut or grab), whether it be made of wood, acrylic, aluminum, or any other similar or derivate.
The majority of CNC routers use a G code that contains all the information translated into coordinates, which the router control board interprets and translates into spindle or motor movements, speeds, rotations, etc.
As previously stated, these instructions are created using a digital file created by CAM (Software of Design) software, which transforms a design for a cut, grab, or mix into the G code needed by a CNC router to function. There are several design programs available on the market, and some of them work with their own type or extension of file, but the most popular ones for creating 2D or 3D designs are DXF and DWG, among others.
Now, every CNC router has a control software or communication method that enables the interpretation of the design. This can be software installed on a computer that is simultaneously connected to the router via USB or a control DSP, the latter of which is essentially a personal computer with specific commands for loading and transferring design files to CNC routers. This system or method is very common, straightforward, dependable, and affordable, and some of our customers use it.
