As a newly hired CNC machining operator, there is a core list of capabilities you must be aware of before you start using any of the equipment. Like any new job, having a complete understanding of the tools you are working with leads to better productivity and faster results. In a factory it is always good to be aware of safety and protocol regulations in addition to the uses that the machines are capable of handling. The following guide gives a brief over view of the difference qualities and advantages that each machine has so that you will be on a fast track to becoming an expert with handling them. Milling This is the most common type of CNC machining that you will come across in your daily work life. The number of axis’s it has describes this process of machine work in accordance to making different 3 dimensional shapes. The number of axis determines what kind of project the machine is capable of and usually varies between four or five parts. The ones with five axis are much more common because they are easy to program with the computer software. You will find yourself working with products that range from plastic to metal and everything in between with this CNC machining process. Most commonly the clients who request your work with this machine are going to becoming from either the industrial or the military industry so the parts generally are very solid heavy structures. The very basic configurations that your milling machining will be set up is either vertical or horizontal milling but they can also be used together in unison to make an even more complex shape. Turning CNC turning is another very standard process that is created under the overall category of CNC machining. This process is also very popular in the factory industry because they are cheap to buy and complete in a timely manner. Plain, taper, contour, fillet and radius shapes are different types of geometrical shapes that turning is able to product. It is easy to remember this if you try and think of chess pieces every time you want to know the difference of the output between turning and milling. The most common types of material you will work with on this CNC machining process are aluminum, steel, copper, or nylon. Unlike the other process which works mainly in military materials and industrial parts, turning is able to make much finer and intricate parts like those for knobs in a car or tiny pieces that make up toys. It’s important to remember that with turning, any shape that is long and thin will not hold up against the grinding axis so make a safety report to your boss if any project comes your way that fits this description. The roughness can also very greatly depending on the type of cutting tool that you choose to use so check the client brief carefully to make sure that your finished work will meet all the requirements requested.
