CNC machining, which stands for “computer numerical control machining,” is a manufacturing technique that is widely adopted. CNC machines fabricate the intended products through a subtractive process, meaning carving out the designed shape out of a block of the original material. CNC machining includes drilling, milling, and turning.
As its name suggests, CNC machining is controlled by computer programming codes. To make CNC work, human intervention is also needed in most of the CNC manufacturing shops. Let’s dig a little deeper and explore the four process of CNC machining’s operation under the control of both humans and computers.
Before the CNC machines start to work, a CAD model has to be designed. A CAD model includes a 2D drawing or 3D solid parts design. There are abundant factors that put limits on the design for the CAD model, such as the tooling’s shape, CNC machine types, and tooling’s capability. Furthermore, the materials’ properties also matter when it comes to designing the CAD models.
