Tool paths to tell your CNC router what to machine. Once you have a design file you are ready to generate tool paths. A bit of a mouthful, but this is also widely used format for storing and exchanging 3D CAD data for transfer between various CAD and CAM programs. STEP: Stands for ‘Standard for the Exchange of Product model data’. IGES: Short for ‘Initial Graphics Exchange Specification’, this 3D file is commonly used in 3D CAD programs as a neutral and geometry format. Most 3D CAD/CAM programs can import STL files.

STL files are a highly portable 3D surface format. STL: A ‘Standard Tessellation Logic’ or 3D triangular mesh file commonly used in 3D printing. Common File FormatsĢD SVG: This stands for Scalable Vector Graphic, and is a 2D format that can be easily resized without loss of quality.ĭXF/DWG: Common 2D CAD formats, also vector based. Usually the output from the stage will be a file that is used in the next stage to generate toolpaths. You can also use existing designs available on the internet.ĭepending on what is to be machined, the design can be 2D or 3D. These days it is most likely to be done in a CAD package or drawing program. This stage is about creating the item to be machined.

You can break down the whole CNC manufacturing process into three stages as shown in the infographic below The CNC Routing Process – Part Design, Defining Cutter Toolpaths and CNC Machining Infographic of the CNC Routing and Milling Process From here you can jog the machine, load, view and run jobs as well as viewing the machine status.

This is the software running on a PC or tablet that provides a human interface used to control the CNC machine. More information on GRBL can be found here. GRBL is the open source firmware used particularly on Arduino CNC based USB controllers.

GRBL runs on microcontrollers and converts gcode to electronic signals that stepper motors controllers can understand. GCode is a text based format and is readable and editable in any text editor.Ĭomputer Aided Design: This an be 2D or 3D software used to create designs and geometry that is used to define machining paths.ĬAM stands for Computer Aided Machining or Computer Aided Machining and is an area of engineering concerned with using computers as tools to aid manufacturing. It can be programmed by hand or for more complex jobs, CAM software can be used. GCode is the language used to program machine motion. Machines are programmed using a language that is G-Code This is the automated method of controlling machine motion. Essential Acronyms for Understanding the CNC Router Process It’s hard to explain the CNC manufacturing unless a few key terms and commonly used acronyms are understood.

However, whether you are a professional designer and CNC machine operator the process much the same for the keen maker as for the professional.įirst, lets get a few acronyms out of the way. Higher end CNC machines from manufacturers such as Haas or Tormach capable of machining steels are definitely in the CNC mill category, with a price tag to match. A CNC milling machine could be said to be more rigid and have a spindle with an inverter for speed control. Often instead of a router a DC motor can be used. Generally speaking, a CNC router is a machine that has a traditional woodworking router mounted to a 3 axis frame. However for the purposes of the beginner or maker or hobbyist the definitions the design process are similar. I use the terms CNC Routing and CNC Milling interchangeably though you can argue about the definitions. There are so many acronyms and technical terms related to CNC machining it can be confusing getting any kind of understanding of what is needed to actually make something! This guide breaks down the process from idea to actually holding a finished part in your hand.
