People are seeing illustrations of beautiful CNC Engraving System more regularly every day. By using a CNC router, complex designs in metal and wood can be sculpted that would be very easy to appreciate. Computer numerical control has its origins in product manufacturing. Original routers, before the development of numerical control, were controlled physically. Basic x-y milling equipment used a router bit to remove material from a solid plate.

Similar to a drill press bit, the router bit has cutting edges on the end and the sides as well. It drills an opening the minute it is dropped into place. Then it is moved in one direction to make a channel the width of the router bit, and multiple passes can create an indent of any size and shape. The router bit is moved in each of the x and y directions using a multi-turn auger, for exact control. Irrespective of how precise it is intended to be, it is still exposed to human error. Furthermore, creating numerous copies of the same design is cumbersome, and subject to problems of consistent replication, again due to the human error aspect.

The effectiveness of numerical control is explained in this case. A router with a exclusive processor controller accepts routing directions. The positioning of the router bit is controled through a control process. Not only accurate, because the commands are executed by computer control they are able to be duplicated. Whenever an exact copy can be made once the pattern has been saved and whenever needed can be reloaded into the machine and created easily and accurately.Although the technology was created by manufacturing, innovative artists soon saw the possibility to create art using numerical control routers. With no wish to create their art with a pencil rather than a router, many artists who have a background in drawing can reproduce a design using a router for more long term works of art.

The link between the artist's drawing and the CNC router commands are a set of computer programs. A program utilized to generate vector graphics is the first of such program functions. This is similar to a raster graphics program, which draws by modifying the color of pixels on a surface. The way each draw a simple shape like a circle will easily demonstrate the difference between the two applications. The raster program merely changes raster color in a circular form. The circle is a straightforward radius in the vector representation. The circle may be scaled as small or as large as needed which is the power of the vector graphics, without any type of loss in the detail. Another benefit of vector graphics would be that the way it represents shapes is similar to the way a router travels to carve that design into metal. A second computer program has the ability to take the vector files and translate them to a set of CNC commands.

The output of the vector graphics is generally a dxf file while the output of a raster graphics is known as a jpg file like photos from a camera or internet photos that have been downloaded. DXF art is commonly what this artwork that is created through this process is called. Artists are able to create beautiful CNC Cutting System exporters from original designs by using this process. Another option is to use DXF files which have already been designed to make the beautiful designs. Very quickly and easily, nearly anyone can start using a CNC machine to create their own unique art.
