In CNC machining, CNC means Computer Numerical Control. It is known as a process being used in the sector of manufacturing. It usually involves the use of latest technologies like computers in order to control all the machine tools involved in the entire machining process. The tools that can be manipulated by computers usually include mills, lathers, grinders, as well as routers. |
On the normal surface, it can look like just a PC is the one who controls all the machines. However, the unique software of the computer as well as its control console are the most important things needed in order to set the system apart for certain use in CNC machining process.
Under CNC machining process, machine tools usually function via numerical controls. A particular computer program is fully customized for a specific object and each of the machines are programmed with standard CNC machining language, which is called as the “G-code”. It essentially controls all of its features like coordination, feed rate, speeds and even its location. With this certain kind of machining process, the computer can control the exact velocity and positioning. This kind of machining process is also used in the production of both plastic and metal parts, therefore widely used in big industries.
How It Works
In this process, a CAD drawing is first created in a 2D or 3D form. After that, a code is created which is needed for the CNC machine to process the drawing. Next, the program is loaded to the machine and finally the operator will run a test of that particular program in order to make sure that no problems will occur during the process. This is called as the trial run and is also referred to as the “cutting air”. Overall, it is a very important step since any mistake with regards to the tool position and speed can actually result in a damaged machine or a scraped part.
Advantages of CNC
There are actually lots of advantages when using this process. It is because it is more precise compared to manual machining and it can also be repeated in almost exactly the same manner whenever you want. Since CNC machines are able to provide precise process and output, this process is can definitely produce extraordinary and complex shapes, which would be almost impossible to achieve by manual or traditional machining process. In addition to that, CNC are widely used in the manufacturing of complex 3D shapes. For more information about CNC, visit Howarth Engineering.
