Application of digital precision measurement technology in machine tool manufacturing

digital precision measurement technology is one of the key technologies in digital manufacturing technology. The development trend of precision measurement technology is to develop sub micron and nano scale high-precision measurement instruments, improve environmental adaptability, enhance robustness, make precision measurement equipment enter the production site, integrate it into machining machines and manufacturing systems, and form an advanced digital closed-loop manufacturing system

the 15 year course of Faro in the United States is actually uneven. The FaroArm series portable coordinate measuring arm of technology company realizes the perfect combination of measuring arm and laser scanning head for the first time in the industry, and realizes non-contact rapid scanning and contact measurement under the same coordinate system. Features: non-contact flexible and fast scanning, obtain point cloud data of curves and surfaces, and the point cloud has no layering; Contact measurement, grasp the accuracy of key feature size and contour; Non contact and contact measurement are perfectly combined in the same coordinate system, and there is no layering in scanning; The scanning head, measuring arm and measuring software are both products of Faro company. The technology is fully shared and the service is more convenient. In practical application, it can greatly shorten the design, production and manufacturing cycle for customers and reduce costs. Quality control can be completed internally. The automatically generated report is suitable for network applications, thus improving the communication between production functional departments and actual different locations; The accuracy is improved. When doing product inspection, users usually define the surface through 5 to 10 points, so that users can inspect the surface quality defined by tens of thousands of point clouds; Automatic SPC can perform automatic statistical process control on multiple samples

CIMCORE company of the United States launched a joint arm measuring machine equipped with an advanced laser scanning measuring system. The material is carbon fiber, and the infinite series also has the function of wireless communication. When used in reverse engineering, not only the measurement speed is fast, but also the real-time display of the measurement process and the seamless splicing of missing measurement data can be realized. The instrument can be used for coordinate measurement, three-dimensional modeling, product mapping, reverse engineering, on-site measurement, mold design and manufacturing, involving design, manufacturing, process testing, testing and final product testing

the scan series of Swiss TESA company uses two linear array CCD components to project and scan the workpiece through the rotation and axial movement of the workpiece, which can realize the accurate detection of the position error and shape error of shaft parts with "partners" to activate various steel trade service providers, the evaluation and comparison of section shape and profile, and the statistical quality analysis, as well as the amplification measurement of parts (such as transition curves, micro grooves, etc.). It can accurately measure the thread, worm and screw rod with full parameter accuracy

German Schneider WMM series shaft and tool measuring instrument has simple operation and high measurement speed, which is especially suitable for workshop inspection stations. The instrument adopts a high-resolution matrix camera, which can quickly obtain measurement data

in the field of precision and performance testing of CNC machine tools, laser interferometer measurement systems and ball instruments produced by famous foreign manufacturers Renishaw, API and HP are widely used in the detection and monitoring of geometric accuracy and motion accuracy of CNC machine tools, both in machine tool manufacturers and machine tool users. Renishaw's laser interferometry system is equipped with high-precision, high-sensitivity temperature, air pressure, humidity sensors and EC10 environmental compensation device, which further improves the measurement accuracy in the working environment; The rmtea six dimensional laser measurement system of API company can measure the errors of six precision items of CNC machine tools at the same time, which shortens the detection time and provides a faster and more efficient precision measurement means for the detection and diagnosis of CNC machine tools on the production site. The MJS series double frequency laser interferometer of Chengdu Institute of tools covers the accuracy standard evaluation methods and indicators of CNC machine tools in China and major industrial countries in the world. The dynamic sampling function can be used for automatic compensation

in terms of non-contact scanning measurement and CMM, the precision CMM of Leitz company is used to measure large gears. The primac1 series horizontal arm measuring machine of DEA company affiliated to hexagon group in Sweden is equipped with 1. The deformation amplification ratio of the recording device of the safety belt tension testing machine should be 50:1. It is equipped with an optical/laser non-contact scanning sensor, which can adapt to the requirements of different measurement environments and tasks. The prorpremium coordinate measuring machine of Zeiss company in Germany is equipped with EagleEye navigation system and controllable measuring pedestal, which can implement high-speed and precise measurement

the laser vector measurement technology based on volume diagonal launched by Optodyne in recent years is a new way to quickly measure and compensate the three-dimensional position error of CNC machine tools and machining centers. This technology was invented and patented by American photodynamic company, which follows asmeb5.54. The prototype of flexible articulated arm measuring machine independently developed by Xi'an Edward measuring machine company in China

test system solution provided by teamtechnik. Based on the modularization of the functional components of the equipment. Independent of the tested parts, the functional components are standardized into modules, which are always consistent in the application process. The equipment is centered on the tested parts, so that the technology after trial inspection can be continuously accumulated and improved
