With the economy entering the New normal, the machine tool industry is facing profound changes. Intelligence and refinement are increasingly becoming the development trend of the machine tool industry. Personalized customization and system solutions are becoming reality.
According to recent data, in September 2015, the production of metal cutting machine tools in China was 60000 units, a decrease of 15.5% compared to the same period last year. From January to September 2015, the production of metal cutting machine tools in China was 570000 units, a decrease of 7.6% compared to the same period last year.
Affected by the domestic macroeconomic situation, the sluggish domestic manufacturing industry and declining demand have led to a rapid decline in the production of metal cutting machine tools in China. However, China is currently formulating the 13th Five Year Plan for the development of intelligent manufacturing. Intelligent manufacturing is a new manufacturing model based on the new generation of information and communication technology. Its prominent feature is that it can effectively shorten the product development cycle, improve production efficiency and product quality, reduce operating costs and resource energy consumption. Promoting intelligent manufacturing, there is hope for a reversal in the production of metal cutting machine tools.
For example, with the expansion of production scale and global industrial transfer in the automotive and parts, aerospace, molds, railway transportation equipment, engineering machinery, and other types of equipment manufacturing industries, as well as the strong demand for multi-level machine tool products in related industries, it will further promote the rapid growth of China's metal cutting machine tool manufacturing industry. Experts predict that the total industrial output value of China's metal cutting machine tool industry will exceed 200 billion yuan in 2015, making it a major global production base for metal cutting machine tools.
Metal cutting machine tools are a widely used and widely used category of machine tools, and in the trend of intelligent manufacturing, promoting intelligent technology transformation is particularly important. The main goal of intelligent technology for metal cutting machine tools is to provide real-time feedback to the controller through intelligent sensing devices on the strain, vibration, thermal deformation and other real-time states generated during the machining process of the machine tool; By adopting targeted control algorithms, the machining trajectory is compensated online to effectively improve machining accuracy, surface quality, and efficiency; Shorten the processing process and improve processing efficiency through intelligent integration of processes and modular processing methods; Realize intelligent interaction between machine tools and between machine tools and people through network technology.
With the continuous maturity of the Internet of Things and cloud computing technology, future intelligent machine tools will take the following forms.
1、 Manufacturing Technology Based on Intelligent Agents
The continuous development of Internet of Things technology, especially the miniaturization and autonomy of various intelligent components, makes it possible for workpieces, cutting tools, and even various working modules of machine tools to exist as intelligent agents.
In the future manufacturing process, the workpiece can serve as the ordering party to determine the process flow, select and control fixtures based on its own characteristics and processing objectives, until the completion of its own quality inspection; The cutting tool can be recommended according to the process requirements, and can be selected in multiple directions with the machine tool and workpiece. The processing parameters can be adjusted according to the working conditions, and the service life can be predicted based on daily use; In the modular processing method, each module can coordinate and coordinate with each other, providing its own usage characteristics and application direction to the control system, as well as proposing rectification or optimization suggestions for the combination plan and deployment instructions issued by the system.
Due to the presence of intelligent agents at all levels, the metal cutting process will transform from the current top-down form to a bottom-up form, fully mobilizing various production and manufacturing factors, and further improving production efficiency.
2、 Open manufacturing mode
Employing increasingly mature and reliable cloud computing technology to empower machine tools with the ability to "manufacture in the cloud". This requires enterprises to have a good foundation in information technology, as well as to overcome many technological difficulties, such as cloud based knowledge manufacturing resources, manufacturing cloud management engines, cloud manufacturing application collaboration, cloud visualization, and other technologies, which are important foundational technologies that need to be overcome in the future.
The intelligence of metal cutting machine tools will make multi variety, small batch, and customized intelligent collaborative manufacturing the main production and manufacturing mode for enterprises, playing an important foundational supporting role in China's transition from a manufacturing powerhouse to a manufacturing powerhouse.
