The basic principle of CNC machining
December 07, 2022
CNC technology is the core of modern advanced manufacturing technology. With the development of science and technology, the structure of mechanical products is more and more complex, and the requirements for product performance, precision and production efficiency are getting higher and higher, and the replacement is frequent. In order to shorten the production cycle and meet the ever-changing demands in the market, the machinery manufacturing industry is undergoing a transition from high volume to small batch and single piece production, and the traditional manufacturing methods can not meet the current technology development and market economy requirements. The application and development of numerical control technology has effectively solved the above problems, which has caused a fundamental change in the traditional manufacturing methods. Now CNC technology has become the basic technology for automation, flexibility and integrated production in the manufacturing industry. Modern CAD/CAM, FMS and CIMS, agile manufacturing and intelligent manufacturing are all based on CNC technology.
CNC technology <br> <br> computer numerical control systems (CNC) has many advantages:
1. Flexible ( <br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br> Features to meet the different needs of users.
2, powerful <br> <br> can take advantage of computer technology and its peripheral equipment, numerical control system enhancements and CNC machine tools. For example, using the computer graphics display function, checking the programmed tool path, correcting programming errors, and verifying the possibility of collision between the tool and the machine tool and the fixture; using the function of computer network communication, it is convenient for the CNC machine to form a production line.
3, high reliability <br> <br> computer numerical control system may use a magnetic tape, floppy disks and other input means, avoids the disadvantages of the conventional information CNC machine tools since the photoelectric reader frequently turn caused the error. Compared with hardware CNC, CNC reduces the hardware circuit as much as possible, significantly reducing solder joints, connectors and external wires, and improving reliability. In addition, computer numerical control systems generally have self-diagnosis function. When the numerical control system fails, it can display fault information, which is convenient for maintenance or prevent operation errors and reduce maintenance downtime. All of this makes the trouble-free running time of modern CNC systems greatly increased.
4, easy to implement since mechatronics <br> <br> computer circuit board and large scale integrated circuits using advanced technology printed circuit layout, as long as the use of several pieces of printed circuit boards to constitute the entire control system, the NC The device, together with the operator panel, is housed in a small CNC box, which strongly promotes mechatronics.
5, the economy is good <br> <br> after using computer numerical control systems, the cost performance is greatly improved, and now not only large enterprises, small and medium enterprises is also the gradual introduction of computer numerical control system.
The basic concept of numerical control machining is numerical control (Numerical Control), which is a method of controlling the movement of the machine tool and its machining process by digital signals, referred to as numerical control (NC).
CNC machine tools: Machine tools that use CNC technology, or machine tools equipped with CNC systems.
CNC system: A program control system in a CNC machine that automatically reads a predetermined program on the input carrier and decodes it to move and machine the workpiece.
