Computer Numerical Control (CNC) precision machining is the use of computers to operate tools such as mills, grinders lathes and routers. Special programming and software run the computers that guide the machines by experienced operators. Using G-Code, numbers are translated into a computer language allowing the customization of objects. Coordination, feed rate, and speed are controlled via the special programming. Precise and accurate machining is the result, and the exact positioning and controlled velocities produce error free products.
How CNC Works
Computer Numerical Control works on the X, Y and Z axis controlling the cutter movements in three dimensions on the CNC machine. The resulting object is finished in precise three-dimensional measurements. Designs are produced in Computer Aided Design (CAD) programs and then translated to coordinates that guide the cutting machine in a language it can understand. An operator then makes a trail run to check for errors, and with this serious step mistakes are caught which results in reduced waste.
Advantages
The accuracy of cnc precision machining results in less waste and lower costs. The object can be produced in repetition, and CNC can produce complex shapes that are impossible with manual processes. The precision machining of three-dimensional objects is possible, and there is no limit to the number that can be produced. The CNC machines even remove the object from the machine, so the manufacturing doesn’t need to slow down. These machines require little monitoring once they are set up, so employees are free to handle other projects.
Operators
Operators should be experts in handling and set up of the machines, but once that is done their job is minimized. The operator simply feeds the instruction set into the computer program, sets up the proper tools, and the computer does the rest. The computer guides the tooling precisely and effectively. Costs are cut because the operator can then move on the next product because the entire manufacturing process is more efficient.
CNC precision machining is now the standard in shops around the world, and the competition is heating up. CNC is an incredible cost effective, accurate and labor saving means to success. A CNC shop costs more to set up, but the payoff is well worth the initial investment.
