The production process is simple: First, a CAD drawing is created (by 2D or 3D software); this is basically the initial design sketch, produced by the computer. Then, a code is created that CNC will be able to understand. The program loads and finally runs a test of the program, which prevents future failures and ensures that the program is free from defects or errors. Reviewing before the process is an important step, as any error in the speed or position of the tools may cause parts to be thrown away or damaged or damage the machine or tools which are involved in the process.
There are many advantages to CNC programming: the process is much more accurate than manual processing, and very simple to replicate, which is great in case of similar projects. Thanks to the precision of CNC machining, this process can produce complex shapes that are almost impossible to duplicate with manual processing. CNC machining is used in the production of many complex 2D and 3D shapes. As a result, CNC plays a major role in jobs that require a high level of accuracy or repetitive tasks that are identical in execution.
CNC is a process of machining operating in the manufacturing sector, involving the use of computers in order to control machine tools, usually in the production process of metal or plastic. Tools that can be controlled in this way include lathes, mills, routers and grinders. CNC stands for Computer Numerical Control.
On the surface, you might be little to think this is the work of a regular computer which controls the machines, yet the computer's unique console control software is what really distinguishes the CNC system, when compared to an average computer.
When working with CNC, machine tools function through numeral control. A custom computer software is made for the particular object, while the machines are programmed with CNC processing language (referred to as G code). It is essential that the program will have full control over all available features such as input rate, coordination, position and speeds. Using CNC processing, the computer can control the exact position and speed at which the machine works.
