The full form of CNC is Computer Numerical Control and CNC Machining is basically a process that is used in the sector of manufacturing, including the machine tools that are controlled by the involvement of computers. The machine tools that are capable of being controlled in this way incorporate mills, lathes, grinders, and routers. At first glance, it might resemble a typical PC that controls the machine tools, yet the PC’s distinctive control console and software are what truly distinguishes the system for the usage in CNC machining. Under the aspect of CNC Machining, the machine tools work through numerical control. A PC program is personalized for an aspect and the CNC machining language is programmed in the machines. This machining language is called G-code which basically has the control of all the attributes like coordination, feed rate, speeds, and location. With the help of cnc machining, the PC can correctly manage the speed and positioning.
The Technicalities of CNC Machining
Computer Numeric Control utilizes the PCs to produce extremely accurate cuts, designs, and angles. These cuts and designs that are made using the CNC exceed the capability of a human. The cnc machining process is utilized in the manufacturing of both plastic and metal parts. In the initial step, a CAD drawing is made, which is either two dimensional or three dimensional. And afterwards, a code is produced on the basis of the understanding of the CNC machine. In the last step, the program is finally loaded, and then the administrator runs a trial of the whole program to check whether there are any issues or not. This test run is termed as ‘cutting air’. Also, it is an essential step because of the fact that any error with tool position and speed could possibly result in a damaged machine or scraped part.
Area Where CNC Machining Process is Utilized
As the CNC machine tools are capable of resisting the extreme environments and conditions that they are exposed to, these machine tools are utilized in almost all industries and a great number of applications as well. The parts that are made utilizing the CNC Machining process have the uses in the following fields –
- Consumer Electronics
- Aerospace, and many more
The Advantages of CNC Machining
When it comes to manufacturing simple as well as complicated designs, there are various benefits that are offered by CNC Machining, like –
- Choice of plastics, metals, alloys
- High levels of precision and accuracy
- Fast turnaround
- Repeatable processes
- Small batch, low volume, and prototype orders
As mentioned above, there are numerous plus points of utilizing CNC Machining. The procedure is more exact than its manual counterpart and it can be performed in the exact same way again and again. As a result of the accuracy that is achieved with the CNC Machining, this procedure can deliver complex shapes that are practically impossible to accomplish with manual machining. CNC Machining is utilized in the creation of numerous complex 3D shapes.
