Remote Diagnosis and Detection Technology for Electrical Control of Intelligent Manufacturing CNC Machine Tools

Abstract

An intelligent manufacturing environment employs internet-based communication and monitoring technologies for fault detection, diagnosis, and monitoring of industrial machines. The monitoring and fault detection are performed remotely without human intervention that predicts faults and ensures specific operational control. This article introduces a rational fault diagnosis process (RFDP) best suited for remote fault detection and diagnosis of CNC machine tools. The proposed process monitors different operational segments of the machine and extracts related data to validate its performance. The interconnection between the segments and fault impact are identified using the transfer learning process. The previously identified faults are used in the state training process to improve detection and diagnosis accuracy. Depending on the operational control continuity, the performance is assessed post the fault diagnosis. The learning paradigm is trained using the machine’s efficiency and rational data processing to predict the transfer states’ faults. The transfer states are modulated based on the efficiency and minimum-maximum control recommended for the CNC machine. This process’s performance is validated using detection accuracy, diagnosis recommendation, downtime, data processing rate, and processing time. From the experimental analysis, it is seen that for the varying data extraction rates, the proposed process improves detection accuracy by 10.14%, diagnosis recommendation by 8.58% and data processing rate by 7.95%, reducing the downtime by 8.85%, and processing by 11.24%.

The Development Trends of Computer Numerical Control (CNC) Machine Tool Technology

“…However, the maturity of using CNC machine tools for remote fault detection and troubleshooting is not yet established. Research is being conducted using transfer learning methods to identify the state of previous faults, train fault troubleshooting, follow a reasonable diagnostic process, monitor different operational parts of the machine, and extract relevant data to verify its performance, aiming to enhance the accuracy of detection and diagnosis and reduce downtime [29]. For the transition of machine tools towards intelligent monitoring, a hierarchical structure is proposed for data and monitoring systems.…”
