1. Internal factors for the development of intelligent manufacturing equipment

The development of productive forces has always been a decisive factor in the development of human society, and the progress of modern science and technology has increased the speed of development and change of human productive forces. Through the integration and deep integration of advanced manufacturing technology, information technology and intelligent technology, intelligent manufacturing equipment will realize the leap-forward development of the productivity of human society. Since the last century, people’s attention to the level of productivity development has mainly focused on the automation of the production process. The increase in the degree of automation has greatly liberated the manual labor in the production process.

However, as human beings demand higher production capacity, production quality and production efficiency, more and more production problems require more mental work to make decisions. Such as extreme manufacturing, ultra-precision processing, high-speed and efficient processing, green manufacturing considering sustainable development issues, etc., are all manufacturing problems that cannot be solved by traditional techniques and mature experience, and intelligent processing equipment is urgently needed to complete them.

1) Extreme manufacturing system problems

As human society continues to challenge extreme conditions such as deep space and deep sea, various extreme manufacturing problems have become the main direction of human productivity development. Such as the one-time molding of large space station cabins; the precision forging of high-strength and super-large components used in deep-sea exploration submersibles; the overall structural parts and their precision welding of 10,000-ton large ships; aircraft manufacturing and hot rolling units Manufacturing and other complex giant system manufacturing problems, etc.

In such extreme conditions, a large number of overall thin-walled structures and complex curved surface structures are often used to meet the extreme service performance requirements of parts. This kind of production problem has high manufacturing costs, complicated manufacturing processes, and expensive trial and error. It is necessary to obtain as much experience and data as possible under limited experimental conditions. Therefore, manufacturing equipment needs to have strong data collection and analysis capabilities. Through real-time tracking and collection of production process data, equipment operating status, workpiece processing quality, and material stress, strain, and other data, combined with physical information systems, correct values Simulation and simulation to achieve effective data analysis and prediction, thereby reducing trial and error costs and improving production capacity.

At the same time, scientists are constantly creating products with new structures and new functions through the excavation of micro-scale material structures and properties and breakthroughs in manufacturing technology. The new nano-manufacturing process needs to integrate nearly billions of electron tubes on a chip of 1 square centimeter; based on the atomic-scale additive manufacturing technology, the heart that can “beat” and the “breathing” function can be assembled through the controllable assembly of macromolecules. Artificial organs such as lung airbags; the quantum computer “Nine Chapters” built by scientists can process “Gaussian Bose sampling” one hundred trillion times faster than the fastest supercomputer; ultra-precision grinding technology has improved the surface processing quality of parts Atomic scales down to the picometer level.

At present, manufacturing technology has gradually entered the picometer-level manufacturing at the atomic and near-atomic scale from millimeter-scale hand-manufacturing to micro- and nano-scale machine manufacturing, which requires a new generation with higher perception capabilities, innovation-driven control, and artificial intelligence. Technology intelligent manufacturing equipment to achieve.

Generally, it can only be ground in the flexible flow channel of complex mixed diamond abrasives, and there are more than 40 process conditions that affect the processing accuracy. With the help of advanced sensor and detection technology, some of the most important process parameters can be extracted through big data analysis and artificial intelligence methods, which requires a new generation of grinding machines to have a higher level of intelligence.

As for the complex processing technology of hard and brittle stone sculpture products, the material composition and structure are complex, each stone has different process characteristics, and the processing parameters of each process will have a greater impact on the tool. With the help of real-time monitoring of the processing process and accurate prediction of the digital model, the process path and parameters can be continuously optimized.

For difficult-to-machine materials such as high-temperature alloys, titanium alloys, high-strength steels, and composite materials, during high-speed cutting, the cutting temperature is high, the tool wear is serious, and the parts are deformed and vibrated during the manufacturing process. Machining accuracy and surface integrity It is difficult to guarantee that complex engineering problems such as nonlinearity, time variation, large strain, high strain rate, high temperature, high pressure, and multi-field coupling of the cutting process must be fully considered, all of which require intelligent manufacturing equipment to have efficient and reliable detection, analysis, and control ability.

3) High-speed and efficient green manufacturing issues

The high-speed, efficient, and green manufacturing process of cutting technology is not a pure geometric manufacturing process, but a typical physical manufacturing process with the strong coupling of force and heat. Materials science, elastic-plastic mechanics, fracture mechanics, heat transfer, kinematics, dynamics, and tribology are involved in the cutting process, various physical phenomena in the cutting process such as cutting force, cutting heat, cutting vibration, and tool wear, etc., are closely related to the processing system composed of the workpiece, tool, machine tool, and fixture.

Factors such as manufacturing error, tool wear, force deformation, heat deformation, positioning error, and measurement error of the processing system will directly affect the processing quality of the part. In the process of intelligent cutting and processing, by combining advanced sensors and detection technology, data technology, intelligent algorithms, and machine tool motion control, real-time monitoring and dynamic control of cutting processing status and surface quality are realized, which requires intelligent manufacturing equipment to have real-time detection and analysis capabilities, data transmission and sharing capabilities, and the ability to respond accurately and quickly to control decisions.
