The development direction of three-dimensional coordinate measuring machines
The development direction of three-dimensional coordinate measuring machines
1. Large-range direction: the representative product is the double-gantry three-coordinate measurement machine and three-dimensional coordinate marking instrument. At present, the measurement accuracy and operation convenience of these two types of products gradually decrease as the measuring range increases. However, with the gradual development and improvement of software functions and control system functions, they can greatly make up for the problems caused by the measuring range. loss of accuracy and operability. This type of equipment is mainly used for reverse and large-scale measurements. Representative products include the three-dimensional coordinate scribing instrument from the Measurement Instrument Research Institute of the China Testing Technology Research Institute. The accuracy is 0.01mm+0.01mmL 0.03mm+0.03mmL
2. Small manual three-dimensional coordinate measuring machine: The current popular three-dimensional coordinate measuring machine has high cost performance and is suitable for the needs of the majority of small and medium-sized enterprises. Due to manual limitations, most of its measurement ranges are within 1000mm. With the development of software technology, its measurement functions continue to improve with the development of software. The disadvantage is that the measurement speed is slow and suitable for small batch testing requirements. The accuracy is greatly affected by human factors. It is a medium-precision measurement requirement for on-site production. The accuracy is mostly: 3.5+1000L/3.5um. Domestic manual manufacturers include Shenzhen Xin Lei Chengdu Starisian Lide, etc.
3. CNC three-dimensional coordinate measuring machine: easy to operate, high precision, automatic measurement and automatic control. Suitable for high-precision measurements. This is the trend of Depp popularization in the next 10 or even 20 years. At present, domestically produced German CNC three-dimensional coordinate measuring machines are restricted by imported key components, making it difficult to popularize and promote them. The prices are generally high, making it difficult for ordinary enterprises to afford them. Grating rulers, CNC measurement software, CNC photoelectric control systems, and CNC three-dimensional probe systems are all affected by imported components. At present, very few independent research and development projects in China only include mechanical components and after-sales service training. Domestic and foreign competition is very difficult, and only low profit prices and cheap and high-quality services occupy a small share of the market. It will be difficult for domestic companies to break through this bottleneck in the short term. High price has always been a difficulty in popularization and promotion.
4. Intelligent fool-type measurement software and control system: Software, motion control systems and measurement operations have always been the weaknesses of operators. Intelligent fool-type measurement software and control systems can enable basic workers in the workshop to operate coordinate machines. , realizing the popular operation of coordinate machines. It is also the trend of future development.
5. Multifunctional three-dimensional probe: The probe can improve the overall measurement level of the coordinate machine and simplify measurement.
Composite function coordinate machine: A multi-functional combination of influence measurement, trigger measurement and laser scanning can maximize the complementary advantages of each function.
6. The application of new materials can gradually improve the measurement function of coordinate machines and optimize products. New new technology materials are another main direction for the future development of coordinate machines.
