If CNC machine works like the Robot, which has to be fed with the program and it follows all your instructions. So how to machine parts is a process used in the manufacturing sector that involves the use of computers to control machine tools. The process is simple as we say, CNC machining process has many kinds, but also depends on what parts of the process you are likely to be more troublesome. Because of the different requirements and production conditions, the manufacturing process is also different. The production efficiency and economic benefit are not the same when the same parts are produced by different processes. Generally, From design drawings to parts,  through a series of manufacturing processes. The machining process of parts is made up of many processes, and each process is composed of station, working step, tool and installation.Some of the common mechanical tools that can be run in CNC lathes, milling machines, drilling machines, turning machines, etc, the main purpose of these machines is to remove the metal part so that it, such as round, rectangular and other appropriate shapes. Once you see a part, a component, you can say what material it is made of, and what kind of manufacturing process, you’ll have a general understanding of the “how to machine parts”. In fact, I think that no one can absolutely understand the process of everything, because the manufacturing industry is a very complex division of the industrial system now. If you really want to understand the actual production, something who say is not as good as the course to learn at the scene.
