CNC is the shorthand for Computer number control. The direct meaning is that computer digital control is a kind of processing technology widely used in manufacturing. It can also be said that it is the mark of the current manufacturing industry. It can be easily realized by CNC. Axis linkage (multi-axis linkage refers to simultaneous machining on multiple axes (including linear coordinates and rotary coordinates) on a machine tool and can coordinate motion simultaneously under the control of a computer numerical control system (CNC). For example, the processing of the hook face, if left from the CNC, is processed with a normal machine tool and is almost impossible to complete.
In addition, the CNC can easily implement a flexible manufacturing system. In fact, if learning CNC is not difficult, it can be said that as long as you play mobile phones, you will use CNC. However, before you learn CNC, it is best to learn. The processing principle of ordinary machine tools [yuán lǐ], as well as the basic mechanical manufacturing knowledge of the drawing and the tolerance, and then the effect, is good. To put it simply, ordinary machine tools are people who directly control the machine tool to process, and CNC is the person who controls the CNC system to control the machining of the machine, thus achieving more complicated and higher-speed machining.
The advantages and disadvantages of CNC machining
① The amount of tooling is reduced, and the messy parts are processed without the need for messy tooling. To change the shape and dimensions of a part, you only need to modify the part’s procedure to suit new product development and retrofits.
②The processing quality is stable, the processing precision (precision) is high, the repeating precision is high, and it is suitable for the processing requirements of the aircraft (aerobat).
③Kinds of (many), small batch production, high production power, can reduce [xuē jiǎn] production preparation, machine tool adjustment, and process inspection (process inspection refers to preventing non-conforming products from flowing into the next process, but for each road At the time of the inspection of the products processed by the process and the main process factors affecting the quality of the product, the machining center counts and the cutting time is reduced by using a preferable cutting amount.
④It can be processed by conventional methods that are difficult to process, and can even process some unobservable processing parts.
Ordinary milling machines are low in price, but inefficient in mass production, the processing quality is greatly affected by the technical level of the operators, and the processing consistency is not good. CNC processing has high efficiency, good processing consistency, and stable quality. However, the cost of machine tools is expensive, and it takes less time to program when the number of machining is small. Requires repairers to have a high level.
