At present, China's manufacturing industry is facing the challenge of industrial upgrading and transformation. The Chinese government has proposed the China Manufacturing 2025 Plan from the national strategic level, vigorously promotes and applies advanced technologies for intelligent manufacturing, and has attracted extensive attention and discussion in various fields such as industry, academia and research. It has brought a shareholder wind to China's manufacturing industry. The digitalization and informationization process of manufacturing enterprises has accelerated. The Internet of Things and industrial big data have brought unlimited imagination to large-scale customized production. All industries and industries are unconsciously protected by intelligent manufacturing. Catalysis, seeking technology upgrades.
Renishaw is the world's leading engineering company with expertise in precision measurement and healthcare. In recent years, Renishaw has been committed to working with schools and companies to contribute our expertise in manufacturing, process and measurement. , the advantages of teaching popularization, jointly explore the role of measurement technology in intelligent manufacturing and application development.
As an important educational partner of Renishaw, Tsinghua University introduced the Renishaw AM250 laser molten metal additive manufacturing system (also known as '3D printing system') as early as 2013. The system was handed over to the Department of Materials Science and Engineering, Tsinghua University. For the research of various metal materials and cutting-edge applications in specific fields (aviation, medical and energy). In 2016, the two sides jointly established the 'Tsinghua University-Renishaw Precision Measurement Laboratory'. The Engineering Training Center is Tsinghua University. The discipline innovation creative practice platform provides students with practical courses such as internship experiments, supports various science and technology competitions, and provides platform services for all kinds of general education of students.
'Tsinghua University-Renishaw Precision Measurement Laboratory' aims to let more students understand the history and development trend of measurement technology, familiar with commonly used digital measurement methods and equipment, enhance measurement practice ability, and cultivate quality awareness in measurement work. Do our best.
The measurement process is an important part of the machining process, and understanding the machining process is the basis for understanding the measurement. The course design takes the machining process as the main line, and focuses on the production precision of the product. It strives to realize the digitization and intelligence of the measurement technology and develop relevant course modules. At present, the measurement direction of the design includes motion accuracy measurement, CNC machine tool internal measurement, intelligent production line online measurement, and part accuracy evaluation measurement. Let the measurement technology participate in the whole process of production, and perform complete measurement before, during, and after the sequence. Control, realize 360-degree dead angle measurement chain in intelligent manufacturing, collect dimensional information in product manufacturing, ensure high efficiency, high precision and flexible production.
Motion accuracy measurement and in-machine measurement based on CNC machine tools
The motion accuracy measurement course focuses on the motion accuracy of linear or rotary motion, such as the accuracy of CNC machine tools or three-coordinate motion. When using laser interferometer, pay attention to the environmental factors affecting measurement, such as air temperature, air pressure, humidity, temperature of the measured material. Etc., the operation process is required to be rigorous and meticulous, and then the accuracy of the equipment is interpreted according to the measurement results and suggestions for improvement are proposed.
CNC machine tool in-machine measurement course study When the machining process is fully automated, how to match the measurement is automated, and the manual measurement control is reduced to zero. If the machining origin is automatically set, the tool parameters are automatically set, and the tool is damaged. Inspection, part deformation control, adaptive machining, etc. Let measurement and processing blend together to better ensure the accuracy of part size.
The intelligent production line online measurement course solves the full size of the on-site products, fast beats, efficient measurement problems, and solves the product size changes caused by temperature changes. The comparison measurement technology perfectly solves these two problems. Cooperating with the robot and processing parameter compensation software. Application, successful realization of in-machine, off-machine full-closed production and parts sorting operations.
The part accuracy assessment course uses the three-coordinate measurement and the final evaluation of the part size in the traditional measurement room. If the factors affecting the accuracy are taken into account in the front stage of the production, and various measurement methods are used for correction and compensation, then the probability of success of the final evaluation of the part is high. , solves the problem of repeated processing of parts, greatly improving efficiency.
Alignment measurement programming and practice
In addition, teacher training is a key part of the development of curriculum modules. Renishaw and Tsinghua University's faculty members strengthen close communication and cooperation. The engineering training center dispatches professional teachers to participate in Renishaw's technical training; at the same time, Renishaw technical engineers participate in auxiliary teaching. In order to better understand the application of measurement technology in teaching, in order to develop more targeted and interactive teaching content.
Reinschau China Training Manager Chen Yunchun said: 'Renishaw and Tsinghua University Engineering Training Center jointly set up a platform, hoping to let college students understand the current mainstream measurement technology and equipment, and explore the elements of precision machining, Renishaw We will also work with you to 'advance with the times' and develop courses that are distinctive and in line with the trend of intelligent manufacturing. We will contribute to the cause of education.
