What Is CNC Machining?

CNC or Computer Numerical Control machining is a manufacturing process where a computer is in charge of the movement of different industrial machines. For example, lathes and milling machines are the most commonly found CNC machines.

CNC machining services are cost-effective, adapting, and compatible with various materials, like aluminum, brass, bronze, copper, plastic, nickel alloys, titanium, stainless steel, etc., and different industries across automotive, medical, aerospace, and consumer electronics for a wide variety of applications. Manufacturers use this process for direct manufacturing and even indirect ones by combining it with other advanced techniques, like rapid prototyping.

How Do the Manufacturers Utilize CNC Machining?

This CNC or Computer Numerical Control manufacturing procedure starts with part designs using CAD (computer-aided design) software. The 3D design consists of the required properties and dimensions for the final part. On the other hand, the experts run the CAD design files through CAM software after the formatting process is over to take out the geometry part and generate the programming code- M-code and G-code.

Thus, the CNC machining program creates the part, coordinating the cutting head with proper guidance.

Advantages of CNC Machining 

Computer Numerical Control (CNC) machining usually is used for metal machining operations, even in low-volume productions. In fact, by utilizing CNC machining services, you can have great benefits in your applications. For example:

  • You can be less dependent on human labor, which means fewer chances of making mistakes. But you may need an efficient CNC machinist and programmer to start this machining process.
  • CNC machining ensures precision in terms of creating parts than manual machines while meeting the specifications.
  • Throughout the production process, manual machines may cause inconsistency after a number of cycles, like in aluminum part productions. In this case, many manufacturing companies prefer using CNC aluminum machining to uphold consistency in the manufacturing process.
  • CNC manufacturing procedure increases production efficiency while lowering the cycle time and reducing waste materials. Besides high-speed machining, CNC allows to design and create complex parts easily and enables the manufacturers to utilize their finances and resources efficiently.
  • CNC manufacturing process lowers production costs by eliminating operational expenses and the need of providing operator training.
