Solution of Machine Tool Fault Prediction
Problems In Machine Tool equipment
In the industrial machine tool industry, the industrial chain is mainly composed of upstream raw materials, midstream various machine tool products and downstream application services. In this industry, the operation of various functions of machine tools and the completed operations are key factors in the production process. Therefore, in the stage of innovation and upgrading of our country's machine tool industry, machine tool manufacturers hope to improve the efficiency of after-sales operation and maintenance, reduce maintenance costs, ensure the market application performance of their products, and predict the health of customer on-site machine tools. End users hope to avoid the loss of production line shutdown due to abnormal machine tool equipment, understand the operating health of machine tool equipment in real time, effectively carry out inspection and maintenance of machine tool equipment, and shorten the troubleshooting time.
According to the problems encountered in the machine tool industry, Witium launched the "machine tool fault prediction system solution", which collects and monitors the cutting tools, motors, reducers and other units in the machine tool equipment, obtains the health status of the equipment, forecasts and alarms, forms the health diagnosis report of the machine tool equipment sub units, and gives maintenance suggestions. This set of fault prediction system solutions can bring great business value to users:
Improve operation and maintenance efficiency and reduce equipment maintenance cost;
Reduce abnormal faults and equipment damage cost;
Predict equipment deterioration and reduce the cost of spare parts;
Reduce failure probability and avoid production line shutdown loss;
Assess equipment risks and prevent potential personal safety hazards;
Apply data analysis to improve equipment quality and process;
The machine tool fault prediction solution uses the Internet of things high-frequency vibration sensor to collect the vibration waveform samples and surface temperature of machine tool equipment, and generate the vibration characteristic samples of machine tool tools and other units; The edge computing gateway collects the three-phase winding temperature and lubricating oil temperature of the machine tool through the platinum resistance to understand the operating load state of the machine tool equipment. Combined with the vibration characteristics of the sensor, the intelligent mechanism model algorithm is used to analyze the big data of the sampled data, and the roughness is detected according to the product indication, so as to realize the gradual deterioration in the cutting process of the equipment, such as tool wear, plastic deformation Fault prediction and diagnosis of poor cutting and vibration intensification; Then upload the data samples and analysis learning results to the witcloud Internet of things data cloud platform through mqtt; The SaaS business cloud platform of the solution provides users with status monitoring, scene monitoring, fault management, operation and maintenance management, equipment management, customer management, authority management and other functions; It also provides data interface function to facilitate users to import equipment status into intelligent factory operation and maintenance platform system. At the same time, the business cloud platform provides professional users with operation status analysis and early warning fault analysis of machine tools and equipment through big data analysis tools, and forms professional machine tool equipment health diagnosis reports and maintenance suggestions.
