Metal cutting machine tool production decline technology intelligent improvement needs to speed up

Under the new normal of the economy, the machine tool industry is facing profound changes. Intelligent and refined have become more and more the development trend of the machine tool industry, personalized customization and system solutions, which are becoming reality.

Metal cutting machine tool production decline technology intelligent improvement needs to speed up
According to the latest data, in September 2015, the output of metal cutting machine tools in China was 60,000 units, a decrease of 15.5% compared with the same period of last year. From January to September 2015, the output of metal cutting machine tools in China was 570,000 units, a decrease of 7.6%.

Affected by the domestic macro economy, the sluggish domestic manufacturing industry and falling demand have caused the output of metal cutting machine tools in China to decline rapidly. However, at present, China is developing a “13th Five-Year” development plan for smart manufacturing. Intelligent manufacturing is a new manufacturing model based on the new generation of information and communication technology. The most prominent feature is that it can effectively shorten the product development cycle, improve production efficiency and product quality, and reduce operating costs and resource and energy consumption. Driving smart manufacturing, metal cutting machine production hopes to reverse.

For example, with the expansion of production scales of automobiles and parts, aerospace, molds, railway transportation equipment, construction machinery and other types of equipment manufacturing, and the global industrial transfer, as well as the strength of related industries for multi-level machine tool products. Demand will further promote the rapid growth of China's metal cutting machine tool manufacturing industry. Relevant experts predict that in 2015 China's metal cutting machine tool industry's total industrial output value will exceed 200 billion yuan, becoming the world's largest metal cutting machine tool production base.

Metal cutting machine tools are the most widely used and largest machine tool category. It is especially important to promote intelligent technology transformation under the tide of intelligent manufacturing. The main goal of the intelligent technology of metal cutting machine tool is to feed back the real-time state of strain, vibration and thermal deformation generated by the machine tool during the machining process to the controller through the intelligent sensing device; by using the targeted control algorithm, the processing trajectory is performed. On-line compensation, which effectively improves machining accuracy, surface quality and machining efficiency; shortens the machining process through process intelligent integration and modular machining, and improves machining efficiency; realizes intelligent interaction between machine tools and machine tools through networked technology.

With the continuous maturity of the Internet of Things and cloud computing technology, the future of intelligent machine tools will take the following form.

First, based on the manufacturing technology of the agent
The continuous development of the Internet of Things technology, especially the miniaturization and autonomy of various intelligent components, makes it possible for the working modules of workpieces, tools and even machine tools to exist as agents.

In the future manufacturing process, the workpiece can be used as an ordering party to determine the process flow, select and control the fixture according to its own characteristics and processing objectives, until the completion of its own quality inspection; the tool can be self-recommended according to the process requirements, and the machine tool, The workpiece is “multi-directional selection”, the processing parameters can be adjusted according to the working conditions, and the service life of the workpiece can be predicted according to the daily use situation; in the modular processing mode, the modules can coordinate with each other and can be controlled to the central control system. Provide your own use characteristics and application direction, you can also propose rectification or optimization of the combination plan and deployment instructions issued by the system.

Due to the existence of agents at all levels, the metal cutting process will be transformed from the current top-down form to the bottom-up form, and all production and manufacturing elements will be fully mobilized, and production efficiency will be further improved.

Second, open manufacturing model
Utilizing increasingly mature and reliable cloud computing technology, it gives the machine the ability to “make the cloud”. This requires enterprises to have a good information base, but also to overcome many technical difficulties, such as the cloud of knowledge manufacturing resources, manufacturing cloud management engine, cloud manufacturing application collaboration, cloud visualization and other technologies are important basic technologies that need to be overcome in the future.

The intelligentization of metal cutting machine tools will make multi-variety, small-volume, customized intelligent collaborative manufacturing become the main production mode of the enterprise, and play an important supporting role in the process of China's manufacturing from a big country to a manufacturing power.
