CNC stands for Laptop Numerical Handle and has been about because the early 1970’s. Let’s look at 1 piece of manufacturing equipment, a drill press:
A drill press can of course be utilised to machine holes. A individual can place a drill in the drill chuck that is secured in the spindle of the drill press. They can then (manually) pick the preferred speed for rotation (generally by switching belt pulleys), and activate the spindle. Then they manually pull on the quill lever to drive the drill into the workpiece becoming machined.
As you can effortlessly see, there is a lot of manual intervention essential to use a drill press to drill holes. A individual is essential to do something almost every single step along the way! Whilst this manual intervention may be acceptable for manufacturing companies if but a small number of holes or workpieces need to be machined, as quantities grow, so does the likelihood for fatigue due to the tediousness of the operation. ( And do note that I’ve utilised a single of the simplest machining operations (drilling) for our instance. There are more difficult machining operations that would demand a considerably greater ability level (and enhance the possible for mistakes resulting in scrap workpieces) of the individual operating the conventional machine tool.
By comparison, the CNC equivalent for a drill press (possibly a CNC machining center or CNC drilling & tapping center) can be programmed to perform this operation in a significantly much more automatic fashion. Every thing that the drill press operator was undertaking manually will now be accomplished by the CNC machine, like: placing the drill in the spindle, activating the spindle, positioning the workpiece under the drill, machining the hole, and turning off the spindle.
As you might currently have guessed, everything that an operator would be essential to do with conventional machine tools is programmable with CNC machines. Once the machine is setup and operating, a CNC machine is fairly easy to hold operating. In reality CNC operators have a tendency to get very bored during lengthy production runs simply because there is so small to do. With some CNC machines, even the workpiece loading procedure has been automated. The CNC has small human intervention, and can work about the clock, day soon after day, performing completely executed operations with zero errors, no fatigue, and no need to have for rest. Common machining technologies necessary a human to be there, operate the machine, do all the measurements, set up, and adjustments for each individual piece manufactured. CNC is more rapidly, safer, much more economical, has significantly less errors, and does all of the little sdjustments and computes the essential operations imediately.
