CNC Knowledge: The development trend of overall equipment measurement technology

The overall instrument for measuring the equipment error is the aircraft carrier for overall equipment measurement technology, and it is a concentrated manifestation of related technologies and theory. Below, the development trend of the overall measurement instrument for the error of the speed of speed measurement is based on precision, efficiency, function, application of new technologies and the scope of use. Limited to the accuracy of the measurement component and the precision of the measurement instrument itself. The method of improving the accuracy of measurement components has been described in the previous article. There are many measures to improve the accuracy of the instrument, including improving the design of the mechanical structure, improving mechanical treatment and assembly accuracy, high provision sensors, collection systems high performance data, effective error compensation algorithms and data processing algorithms. Among them, the search results in error compensation of the measurement machine to three coordinates are used to develop a separation and error compensation algorithm for the development of the structural characteristics of the machine to measure the special error. The efficiency of the measurement and precision are important performance indicators for the measurement of the instruments. Currently, the overall Error equipment measurement instrument is much higher than the equipment measurement center, but there is still room for continuous improvement.

With the rapid development of mechanical dynamics and improving soft and computer equipment levels, dynamic research in the field of equipment transmission has been very wide and in -depth. And the overall measurement of research errors on mobility is almost empty. In order to further improve the measurement effectiveness of the overall measurement meter instrument, it is necessary to study in depth the overall measurement of engine errors. On the other hand, the speed of optimization suggestions in mechanical, electric and control strategies. The training conditions, the influence factors and the laws of the “OFF” phenomenon to the overall extent of speed equipment errors are also key problems that must be studied in urgent research. In addition, the introduction of robotic power supply and visual methods of the machine to reduce measurement help time is also an effective measure to improve overall efficiency. Currently, overall technology for measuring equipment errors is mainly used for production by cylindrical equipment measures. Surface field of gears and line gears.

With the rapid development of the robot reducer industry in my country, the overall measurement instrument for the error used to swing a needle wheel component is also one of the development directions. The overall error measurement instrument is very simple and the measure can only be carried out two rotary movements. Compared to the equipment measurement center, it is not only sensitive to environmental factors, but also for simple forms of error and few errors, and it is easy to obtain real -time compensation. Consequently, the overall error measurement instrument is the most suitable measurement instrument for the production site. For large gears and small gears which are difficult to measure in conventional methods, the development of a measuring device based on global error is also a research management which can make significant progress.

There are two areas of research which must focus on basic theories in terms of basic theory. The first is to solve the main keys to basic theory more, including the precise calculation of the theoretical unit curve of the global error in the state of the axial movement error and the error of measurement component, further improves the accuracy of the automatic determination algorithm of the teeth assessment area and its luku lu. Conical engarges, surface problems, large care and other transmission elements. In addition, poor general components has always been one of the important factors that affect the overall measure of errors and promotion and application. The principle of measuring the current global error requires that the measurement element and the gear module, the pressure angle and the basic circular tooth distance must be obtained. With the support of modern CNC technology, the use of special measurement elements to improve the generality of the overall error measurement component is also an area of ​​research that may have reached major breakthroughs in the near future.

As a significant part of the first theory of equipment of my country’s equipment, the overall technology for measuring errors in equipment error played an important role in improving the overall level of technology of the ‘Equipment industry in my country. Although with the popularization of the Gear Measure Center, the development and application of global technology for measuring equipment in the past 20 years have entered a period of strangulation, but we must see nature Advanced technology and the advantages of certain segments in segments in a few segments. Once the equipment measurement center has been applied to a large number of applications, its purchase cost, its high environmental requirements and low measurement efficiency, insufficient insufficiency in working hours and small information is gradually emerged. With in -depth research and the gradual solution of key problems of the basic theory of the overall error measurement of the equipment, the overall accuracy of the measurement of errors in equipment error and lack of flexibility are overcome and compensated. The error measurement of the equipment is being demonstrated. At the same time, with technological progress in the fields of computers, sensors, CNC systems and continuous development of activation technology such as the Internet of Things, Cloud Computing and Megadors, new technical conditions The equipment and testing of equipment appeared. Under the conditions of new technical conditions, certain traditional difficulties in the overall extent of equipment errors have obtained a new solution, and the traditional benefits of high measurement efficiency and complete information is greater.
