What is CNC machining

What is the difference between CNC, CNC machining, and CNC mahine?

CNC, CNC machining, and CNC machine look very similar in words, however, they stand for different things, in this article, we will explain the difference between them in more detail.

OK, let’s start.

First of all, what does CNC mean? 

CNC stands for computer numerical control. It is a method for automating the control of machine tools by means of a computer. There are kinds of CNC systems in the market, for example, FUNAC, Siemens, Mitsubishi, and some machine tool manufacturers have their own CNC control system as well.

Secondly, what is the definition of CNC machining?

CNC machining is a subtractive manufacturing process, which is often
presented in contrast to the additive manufacturing process, such as 3D printing or injection molding.

CNC machining process is typically controlled by a computerized system, The machine tools are directed by the program to remove layers of material from a workpiece, and produce the desired part.

This process can be used for a wide variety of materials, including the most common use metals of aluminum, steel, brass, and plastics of ABS, Nylon, Delrin, as well as foam, wood, and composites. We will talk about materials more in another blog. And finds application in a variety of industries, such as  consumer electronics, automotive, robotics, aerospace, and medical.

Last question, what is a CNC machine?

CNC machine is a machine tool that cuts or removes material from the workpiece as programmed on the controller. It is capable of autonomously performing the operations of CNC machining.

Till now, you may know the difference, but is there any other question on your mind?

  • How does CNC machine produce a part?

The process is pretty straightforward and involves the following steps: 

1. Design the part.
Use CAD software to design a 2D or 3D model of the part you want.

2. CNC programming.
Use CAM software to convert the CAD model into G-code. It stands for “Geometric Code”. G-code is the language to tell a machine what to do or how to do something.

3. Machine setup.
This step, includes loading the proper toolings, installing workholding, setting tool length offsets, setting part zero and work offset, loading the CNC program, dry run, adjusting offsets as needed, checking the coolant, etc. and Part Zero is the axis position that corresponds to 0, 0, 0 in the CAD model of the part.

4.Machine the part
This G-code controls the motion of the tool, the workpiece, and tool changes, to produce a custom-design part.
