The Power of CNC Routers and Their Application in Manufacturing

CNC routers, also known as CNC routers that are computer numerically controlled, are machines that cut or rout patterns of various shapes made from metals, wood, plastics and foam as well as a variety of different materials. They are able to cut mechanically complex shapes more quickly and with greater precision, accuracy, and repeatability than a human operator. 

They can be extremely helpful to industries like signs, cabinet manufacturing as well as plastics fabrication among other industries to tackle large tasks that require precise components quickly and efficiently. You can also know more about CNC routers via www.omni-cnc.com/cncrouter. CNC routers are available in standard table sizes that range from 2' x 2' up to 5'x10 Some manufacturers also create custom machines that are 12-16 or greater. 

They've been around for quite some time however, they have gained popularity because of their improved performance and the advancements in software. 3D moves in Three Directions CNC routers are able to cut and move in three directions, commonly referred to as the X,Y, and Z axis. The X axis represents the left-to-right motion, while the Y axis is the forward-to-back movement, and the Z axis is upward or downward movement. 

Coordinates are entered in it by the operator or by a software program, and the movement can be controlled through the self-contained control system. Some come with the option for a vacuum hold down system that utilizes pumps to draw air over the top of the router to hold the material that is being routed. 

 

An Engineer’s Guide to CNC Machining CAD-CAM

Computer Numerical Control (CNC) of manufacturing machines such as lathes and mills was the next stage of development from Numerical Control (NC). NC control had allowed the machines to be run automatically using a fixed program for the first time.

This increased automation of the manufacturing processes led to considerable improvements in the consistency and quality of components. The program was, however, long winded to create and difficult to alter.

The addition of a computer within the machine allowed the program to be viewed and edited making it easy for alterations to be made to what had previously been a fixed program. This allowed operators to write programs directly into the machine and update and optimise them as they went. This required a new breed of machine operators who had the skill and training required to program the machine from engineering drawings in addition to their traditional skills.

The next stage of development was Computer Aided Manufacture (CAM), this allowed the program to be created offline from the machine, not by typing in dimensions from a paper drawing, but by taking the geometry directly from Computer Aid Design (CAD) files. A software package would be used to create the program from 2 Dimensional CAD data of the geometry and then add tool and speed/feed information.

This program could then be post processed into a language appropriate to the machine being used. This development further increased the required computer skills of the machinists but made programming of complex shapes just as simple as creating simple shapes. It also reduced the chances of errors within the program as more of the programming was automated.

The current state of the art is 3D CAD/CAM, which allows programs to be created directly from the 3D solid models created by the design engineers. This technology allows parts to be machined without any from of paper drawing, as all the tool paths are derived from the 3D model.
