Test work of waterjet cutting equipment
The test work of the waterjet cutting machine should test the positioning accuracy, repeatability, dynamic path accuracy, speed range and smoothness of the machine tool.
The operator uses the laser interferometer to test the linear positioning accuracy and repeatability. Test each axis of the machine tool individually. The interferometer, which is actually a laser, divides the laser beam and measures the wavelength change between the unchanged part and the changed part. Since the wavelength of the laser is very small, this measurement method is extremely accurate.
The laser is continuous light, which means that all parts of the laser have the same wavelength and state. Use optical components (special mirrors). Fix a set of optical components on the cutting head. Other optical components are placed at one end of the machine stroke. The laser is shot into the optical assembly of the cutting head, and then the vertical component is reflected back. The operation of the waterjet device is actually that the remaining light beam (level component) continues to enter the optical component fixed at one end of the machine, and then is reflected back. With reference to two wavelengths, the precise size of the moving optical component is given, which is accurate to several millionths of an inch.
During the entire stroke, the cutting head moves 1 or 2 inches on the shaft at a time, pauses for one second, and records a deviation, and then moves to the next position to record the deviation, so that linear positioning accuracy can be tested. In fact, it takes 6-12 hours to test the accuracy and repeatability of linear positioning with a laser. It is worth noting that it depends on the size of the machine and the quality standards followed by the manufacturer.
With the progress of our modern science and technology, especially the development of microelectronics technology and computer application technology, mechanical manufacturing technology has added new connotations. The advancement of natural science has promoted the development of new technologies and the innovation, development and improvement of traditional technologies, resulting in emerging material technologies, new cutting processing technologies, large-scale power generation and transmission technologies, nuclear energy technologies, microelectronics technologies, automation technologies, lasers Technology, biotechnology and system engineering technology. In the 21st century, with the rapid development of science and technology such as microelectronics and computers, communications, networks, information and automation, a "third wave" with information technology as the core has been set off, which is pushing mankind into the most industrial economic era. The heyday.
It is precisely because of the extensive penetration, application and derivation of high-tech science and technology such as waterjet in the manufacturing field that it has promoted profound changes in the manufacturing industry, greatly expanded the depth and breadth of manufacturing activities, and promoted the manufacturing industry to become more and more advanced. The direction of automation, integration and networking is booming.
