Laser Cutting Technology Recently, the city of Minsk, Belarus, has experienced heavy fog and a large number of flights have been cancelled or delayed. The crew of a Belarusian airline flight, with almost zero visibility, chose to risk the autopilot landing system, so that the aircraft eventually landed safely. At that time, from the perspective of the pilot's cockpit, there was only a white curtain outside the window. The crew risked to believe in the automatic driving landing system. First, the situation was urgent. Second, the aircraft itself believed that the aircraft itself had good safety performance. In order to improve the quality of aircraft, modern scientists have been committed to introducing advanced manufacturing processes into aircraft manufacturing.https://www.htpow.com/industrial-laser-c-38_48.htmlLaser cutting technology is one of them, waterproof laser pointer cutting technology has the characteristics of high efficiency, low energy consumption, short process, good performance, digitization and intelligence in the aerospace field. Laser cutting materials in the aerospace industry are titanium alloys, nickel alloys, chromium alloys, aluminum alloys, tantalum oxide, stainless steel, molybdenum titanate, plastics and composites. Laser cutting can be used to process aircraft skins, honeycomb structures, frames, wing bins, tail siding, helicopter main rotors, engine casings and flame tubes. Laser cutting generally uses continuous output laser YAG and CO2 lasers, as well as high-repetition CO2 pulsed lasers.https://www.htpow.com/10mw-green-usb-laser-pointer-pen-p-1153.htmlgreen laser pointerThe distance between the cutting head and the workpiece and the perpendicularity of the nozzle to the surface of the workpiece during the cutting process are two extremely important factors. Directly affect the quality of the processing, so in order to improve the quality of cutting and reduce the production of waste, special sensors need to be installed on the cutting head to ensure stable and consistent cutting quality and increase process safety.https://www.htpow.com/htpow-blue-ultra-power-laser-pointer-30w-class-iv-laser-p-1106.htmlWhen the usb laser pointer cutting head changes the shape of the workpiece and the surface is uneven, the sensor automatically detects the change and automatically adjusts the height according to the change, so that the distance from the surface of the workpiece is always consistent, the material can be processed faster without continuously monitoring the present. The displacement sensor adopted at home and abroad is basically a capacitive type, and its structure and shape are adapted to the processing head, and is equipped with a detection signal processing unit.Displacement measurement is one of the most basic measurement tasks. According to whether the sensor is in contact with the workpiece to be tested, the displacement sensor can be divided into contact type and non-contact type. Compared with the contact sensor, the non-contact sensor guarantees high resolution. At the same time, it has a fast dynamic response, low hysteresis error, and even zero.https://www.htpow.com/488nm-lasers-c-27_116.htmlNon-contact sensors, sometimes called proximity sensors, the earliest application is a proximity switch, that is, when the detected object approaches a sensitive distance to a sensitive probe, a switching signal is given. The current proximity sensor has been developed to detect not only objects. With or without, it gives the distance of the object from the sensitive probe and provides information about the shape and spatial position of the workpiece.Because military laser pointer can be used to measure the displacement of moving objects, this kind of sensor is also called non-contact displacement sensor. Commonly used displacement sensors include hysteresis telescopic displacement sensor, eddy current displacement sensor, capacitive displacement sensor, inductor displacement sensor and so on.According to the principle of various sensors, the capacitance sensor has high sensitivity and has the following characteristics: good dynamic response, because the electrostatic attraction between the plates is small, the required energy is very small, and the movable part can be made very small and thin. Therefore, its natural frequency is very high, its dynamic response time is short, and it can work at frequencies of several megahertz, which is especially suitable for dynamic measurement.The utility model has the advantages of simple structure, strong adaptability, easy manufacture, easy to ensure high precision, and can be made into a small-sized sensor to realize special measurement, and can work in a harsh environment such as high and low temperature, strong radiation and strong magnetic field, and can withstand high pressure and high. Shock, overload, etc. The 488nm laser pointer is small and the temperature coefficient is small. Since the capacitance value of the capacitance sensor is independent of the electrode material, a material with a low temperature coefficient can be selected, and a good stability can be ensured when the external temperature is stable. The larger relative change is limited only by the linear region, and its value can reach 100% or more, which can guarantee the resolution and measurement range of the sensor.
