Computer numerical control or CNC machining for short offers a number of productivity benefits that can help speed up the turnaround batches of products, improve the security of manufacturing, and deliver prototypes quickly. We will examine all of these features in this brief guide.

First of all, CNC machining can dramatically increase the speed of getting a new design for production. This is because a typical CNC lathe or machine accepts CAD drawings as an instruction set on how to produce the product. The CAD drawing is a 3D computer model of the component that needs to be made and is imported into the CNC machine's computer.

This means it is possible for a product designer to design a complex product with many components on a computer, then send the instructions to each component to individual machines on the factory floor for production. This means it is extremely quick to turn a CAD drawing into a finished product.

As a result of the increased computing power of the PCs found in most product designers' offices, it is possible to send a CAD of a prototype to a factory equipped with CNC machining and produce the first prototype using the same machines that will produce the actual finished product.

While it takes a bit of time to set up a machine to produce a prototype, it is quicker than producing a model first, and by creating this initial version of the product on a production machine, it is possible to eliminate any potential issues with the design early on in the process. The same may not be possible with a model, because these are not typically make using a production-quality machine.
