It may not strike you as a particularly fascinating subject but the use of CNC Milling such as you would see the company website of https://www.parallelprecision.co.uk/cnc-millingis an intriguing and beguiling process. Long gone are the days of relying on the human eye and a lathe to get the right results. That’s not to say that the human element is taken out of the process you still need a human to program the instructions into it before it will attempt to cut and drill for you.
CNC or computer numerical controlled milling is a precise operation that can produce the most intricate and complicated results for difficult jobs. As with a drill the subject in question to be milled is spin at high speeds and a rotating axis. The benefit of a CNC milling machine is that it can move around the object on a variety of axes. This means that the object can have holes added, slots produce in the surface and then be cut into whatever particular shape is needed for the job. This has had fundamental effects on the business of engineering and design as it allows developers to work and think out a bespoke shape that previously could not be achieved on the available equipment. The sheer fact that the object to be worked can be moved around the milling machine is a real revolution as previously the object to be worked could only be milled on a single linear rotation that you get with a simple drill.
The CNC milling machine works on an W, X, Y and Z axes. The procedure is programmed in along which axes is needed at certain points to work the object into the shape required. Each letter represents an axis movement. Z is vertical which was unheard of before and X and Y and the traditional horizontal or back and for axis. W represents another new development as this is a diagonal axis. This is just the basic machine! A five axis mill needs specialist training in Computer aided manufacturing as really intricate and complex pieces can designed and created way beyond the skill and ability of human. The use of CNC milling is generally set with producing the bespoke and specific at present. For more established and mundane work it is still thought that a more traditional mass approach with traditional machines is required but this is starting to change as costs are being brought down. Metal is the most common cut material but the CNC is more than capable of utilising any other manufacturing element you can think of.
