Explaining CNC Machining Centers

Production facilities that run more than one CNC machine at a time are called CNC machining centers. These groups of CNC machines are called cells. These machines are capable of long production runs with no human supervision. Parts can be created and quality control done by the computer's lasers and sensors. Automatic processing machines have changed the manufacturing process and made material handling much easier. Large quantities of products that are high quality can now be created very quickly.

Prior to CNC, CNC machining centers used NC machines. NC stood for numerically controlled. Unlike CNC machines, the operating parameters could not be changed on a NC machine. NC machines were the basis for the first CNC machines. They used the hardware from the NC machines and the computer made calculations for tool compensation. CNC machines have improved significantly over the last decade. Now CNC machines have developed to the point that they can detect errors or machinery failure and place a call to the operator even if he/she is not on site, for example on a weekend. Some machines are even smart enough to choose another part and run it while waiting for the operator to correct the error in the program or replace the part that is faulty. The CNC machine can be thought of as a manufacturing extension of the robotics industry.

CNC machining centers use computer controlled machines. CNC is an acronym that stands for computer numerical control. Specifically, the computer controls a machine tool. On a lathe machine, the tool is used to selectively remove material and create specific shapes. Computer programs can be used to create and control the tools so that they perform the right actions in the right order. In the case of metal lathes, the CNC program is necessary to be sure that thread creation is done accurately and precisely.

The manufacturing industry has been changed drastically by CNC machining centers. CNC has allowed for accurate straight line cuts and difficult 3-D designs have become very easy to manufacture. Human interaction is no longer necessary every step of the way. Automation has also made significant improvements to the quality and consistency of the products being made. Errors in the production process have been reduced. CNC automation also controls tool changes, reducing the amount of time the operator needs to spend working on the machine. Job shop cell production has increased dramatically since the addition of automated software.
