What is CNC machining and how does it work?

Sage Metal Parts > Blog > What is CNC machining and how does it work?

CNC stands for Computer Numerical Control. It is compatible with a wide variety of materials. These include plastics and metals. CNC machining is more in tune with metals; especially aluminum, stainless steel and titanium, but companies have also sought the adaptability of plastics to CNC machining.

CNC machining represents subtractive manufacturing. Theoretically: this means to deduct from an original piece. The process starts with a block of material (called a blank); Then; CNC machining starts to cut away material until the finished part is created. Cutters and spinning tools are important parts of the procedure to shape and mold the original piece. Somewhat like sculpture or pottery. CNC machining is best for low to mid volume production and has splendid dimensional accuracy. It works well with many materials including wood, metals, and plastics.

CNC machining needs a skilled machinist to choose usage of tools, cutting path, and repositioning of the material. CNC machining requires cleanup after use because it cuts and sculpts away from the material until the desired form is established.
