In computer-numerical control (CNC) machining, preprogrammed computer software directs the movement of factory tools and machinery through preprogrammed computer programs. The use of this type of CNC cutting machine versus manual machining can improve accuracy, speed, safety, efficiency, and most importantly, reduce costs.
Manufacturers rely heavily on computer-numerical control (CNC) machining, which effectively now use a robot to carry out operations once carried out by engineers using routers, shaping machines, vertical millers and centre lathes.
Why is CNC Machining Beneficial?
As a result of the many advantages of CNC cutting machines, operator-required equipment has been replaced in some cases entirely. Manufacturers in a wide variety of industries benefit from CNC machining in fabrication and manufacturing, as it provides efficient, expedient, and precise production capability ideal for producing large quantities of items. The primary advantages of CNC machining include:
- CNC machines are highly accurate, ensuring consistent product quality: Compared to manual machining, the process is more precise and can be repeated in exactly the same way time and time again.
- The result is a faster, more efficient process: Automating the manufacturing process enables the machines to be controlled by computers, which increases the speed and quality of the production. It is more efficient than manual machining since machines do not tire or require breaks.
- Safety is another advantage for CNC operators: Since CNC machines operate behind a guard or transparent safety door, they are far safer than manually operated machines.
- The CNC process is cheaper: Traditionally, one operator operated each machine. With a CNC router, one skilled operator can operate several machines simultaneously. CNC machines are so accurate that they reduce errors in the manufacturing process and eliminate waste.
CNC Machine Types
The majority of CNC arsenals today are completely electronic. Some common CNC-controlled processes include laser cutting, hole punching, and ultrasonic welding. Among the most popular CNC machines are:
CNC Mills: Utilising computerized controls and rotating multi-point cutting tools, this is a machining process that gradually removes material from a workpiece to create a custom-designed part or product. It can be used to machine a variety of materials, including metals, plastics, glass, and wood, and to produce a variety of custom-designed parts and products.
CNC Lathes: Various operations can be performed on wood and metals, such as turning, cutting, and drilling. While the cutting tool performs various operations on the workpiece, the workpiece is held in place and rotated by a spindle.
