CNC stands for Computer Numerical Control. The CNC machining is the process that has control machine tools working with the help of computers. The process is vital in the manufacturing industries and is used to control tools like mills, routers, grinders and lathes. The machining looks like a normal PC which controls the machines but what is really different is its unique console for software and control.
The machine tools working under CNC machining function using a numerical control. The machines and objects are programmed with a machine language. The machining language is a computer program, which controls its features, such as location, coordination, feed rate and speeds. Using the machining one can control the position and velocity using a computer. Both metal and plastic parts can be manufactured using CNC machining.
How CNC works?
With CNC machines the operator does not have much to do. The things are already programmed to work with the conventional machine tools using the machine programs. Once the machine is setup, there is not much to do on running as everything is automated. The work-piece loading process is also automatic with the CNC. Some programmable functions under CNC are:
- Programmable accessories
The machines can be helpful when it can move the work-piece using more the two axes. The specific CNC machine can do a lot more with right programmable accessories. All CNC machines are programmed in several ways. Any function can be programmed on CNC machine tools. Automatic tool charger, coolant and spindle speed and activation are some examples of one machine type.
- Motion control
The CNC machines have axes which are the two or more programmable directions of motion. The axis of motion can be rotary on circular path or can be linear on the straight line. The complexity of the CNC can be specified with the number of axes it has for the purpose of causing the motions in manufacturing process.
- CNC program
The CNC program is instruction set which is written in sentence-like format. The instruction is a collection of CNC words that makes the machine work the way it should. Step by step and sequential order of executing the control is done by CNC program.
- CNC control
The CNC control reads the CNC program and interprets it. The control activates the suitable machine function and follows the series of commands in right order.
The CNC machines can be used to create parts in less time. Using the machining one can manufacture items that would take normally lot of steps.
The machining can help the operator to fully use the raw materials with accuracy. This reduces wastes, which in return reduces the loss and increase the profits.
As the process of fabrication is automatic the operator has not much involvement in process. This creates safe work environment for the operators.
The CNC is very simple to use once you have learnt the ways. There is no complexity as all the tools are programmed to be automatic.
- Less cost of production
As the machines perform all the work accurately with less intervention, the cost of production is very less.
- Better efficiency
The CNC machines can detect small error and stops the operation to prevent the wastage. Thus the using the machines, the efficiency can be improved.
- High standard
The machining follows the high standard of fabrication and metal working along with high speed of production.
The machining provides accuracy in the process. Once the process has started, it does not stop until goods are finished.
- Happy customers
Manufacturing is fast using the machining. As a result the good are delivered and shipped on time. Products are of high quality, consistent and accurate. This provides a number of happy and satisfied customers.
