A CNC wood router is a CNC router tool that creates objects from wood. CNC stands for computer numerical control. The CNC works on the Cartesian coordinate system (X, Y, Z) for 3D motion control. Parts of a project can be designed in the computer with a CAD/CAM program, and then cut automatically using a router or other cutters to produce a ...
By converting a CAD design file into a CAM file, the CNC Router is able to read relevant information and produce a highly accurate finished product. Styrofoam [5] can also be cut using a CNC router, making it an ideal material for creating detailed prototypes, signage, and architectural models.
CAM software automates the process of converting 3D models into tool paths, the route the multiaxis machine takes to mill a part (Fig. 1). This software takes into account the different parameters of the tool head (in the case of a CNC router, this would be the bit size), dimensions of the blank, and any constraints the machine may have.
CNC machines use G-code and M-code in order to control the machine and the positioning of the spindle. Canned cycles use G-code to machine specific features such as flat-bottom pockets, drilling, or tapping cycles. [3] These make use of 2.5 axis machines, and are used more in education then industry.
The fundamental basis for creating the cutter paths suitable for CNC milling are functions that can find valid cutter locations, and stringing them together in a series. There are two broad and conflicting approaches to the problem of generating valid cutter locations, given a CAD model and a tool definition: calculation by offsets, and ...
The part program is a sequence of instruction that describe the work that is to be done to a part. Typically these instructions are generated in Computer-aided manufacturing software and are then fed into the computer numerical control (CNC) software on the machines, such as drills, lathes, mills, grinders, routers, that are performing work on the part.
CNC stands for "computer numerical control". CNC mills or routers include proprietary software which interprets 2D vector drawings or 3D models and converts this information to a G-code, which represents specific CNC functions in an alphanumeric format, which the CNC mill can interpret.
G-code (abbreviation for geometric code; also called RS-274 [citation needed]) is the most widely used computer numerical control (CNC) and 3D printing programming language. It is used mainly in computer-aided manufacturing to control automated machine tools, as well as for 3D-printer slicer applications. G-code has many variants.
