The Power of CNC Routers and Their Application in Manufacturing
CNC routers, or computer numerically controlled routers, are production machines used to cut out or rout shapes in various shapes from wood, metals, plastics, foam and a variety of other materials. They can mechanically cut out complex shapes much faster and with better accuracy, repeatability and precision than by a human operator. They can greatly help industries such as cabinet making, signs, plastics fabrication and many others to take on large jobs that need precise parts quickly and accurately.
CNC routers come in standard table sizes ranging from 2' x 2' to 5' x 10,' and some manufacturers will build custom machines up to 12' x 16' or larger. They have been available for a long time, but have increased in popularity due to their increased speed and software advances.
Move in Three Directions
CNC routers can move and cut in three directions often called the X, Y, and Z axis. The X axis is the left-to-right movement, while the Y axis is the front-to-back movement and Z axis is the vertical or up-and-down movement. Coordinates are entered into the it either by the operator or software program and movement is controlled by the self contained control system.
Available Features
Many come with an option of a vacuum hold down system that uses a pump to pull air through the router's top to hold down materials being routed. They may also feature an automatic tool changer option that utilizes robotics to change out up to 10-different tools during a job. The tool changer option can greatly increase the speed and productivity during jobs. Some newer models offer print-to-cut cameras which are mounted on the routers and find registration marks printed on materials to ensure the most accurate and precise routing possible.
Once Programmed, Needs Only Supervision to Do the Job
CNC routers require interfacing with the machine through software that can create or import files that the operator inputs. They rely on the spindle to rotate a cutting tool or router bit to perform the routing work. Once the instructions for the routing of the item have been entered, the same program can be stored in the computer and used over and over again to make the products at another time. This allows them to make identical parts without reprogramming the machine. The operator needs only to program the job and periodically supervise and supply materials to the machine to make sure the job is running properly.
CNC routers enable complex tasks to be done at production speeds and repeated with uniform quality. They produce end products at a speed and accuracy that is not achievable by a human operator.
A CNC router takes out the fault of human error, speeding up the manufacturing process to create a uniform product every time. It cuts down on costs as the computer creates and programs the router to do the job. Commonly-used job files can be saved and brought up to repeat projects over and over again.
