Explaining CNC Machining Centers

CNC machining centers are production facilities that run a number of CNC machines simultaneously. This is commonly called a machine cell. CNC machines can run for long periods of time with no operator interaction or supervision. They are capable of creating parts and using sensors and lasers to check them for quality control. The presence of automatic processing machines has been a turning point for product manufacturers. They are now able to create large quantities of high quality products in very short periods of time.

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 have groups of computer controlled machines. The process called computer numerical control is called CNC for short. Instead of a human operator, the computer is given control of the tools used by the machine. In the case of the lathe machine, these tools are used to cut and abrade a block of material into different shapes. Using a computer eliminates the chances for human error. This is especially important in the case of threading processes. A metal lathe is used to cut threads into bolts and screws and ensures that the threads are accurately and precisely cut.

The creation of CNC machining centers has changed the manufacturing industry. Difficult 3-D designs and precise straight line cuts have become simple to create with CNC machines. There is no longer any need for a full time operator. CNC automation has made it possible to create better quality products more consistently. Production errors are no longer the manufacturers biggest concern. Tool changes are now controlled by the computer, which makes material handling easier. Production times and profits have increased significantly since the addition of computers to the machine process.
