To achieve zero-defect production during computer numerical control (CNC) machining processes, it is imperative to develop effective diagnosis systems to detect anomalies efficiently. However, due to the dynamic conditions of the machine and tooling during machining processes, the relevant diagnosis systems currently adopted in industries are incompetent. To address this issue, this paper presents a novel data-driven diagnosis system for anomalies. In this system, power data for condition monitoring are continuously collected during dynamic machining processes to support online diagnosis analysis. To facilitate the analysis, preprocessing mechanisms have been designed to denoise, normalize, and align the monitored data. Important features are extracted from the monitored data and thresholds are defined to identify anomalies. Considering the dynamic conditions of the machine and tooling during machining processes, the thresholds used to identify anomalies can vary. Based on historical data, the values of thresholds are optimized using a fruit fly optimization (FFO) algorithm to achieve more accurate detection. Practical case studies were used to validate the system, thereby demonstrating the potential and effectiveness of the system for industrial applications.

Recently, sequence anomaly detection has been widely used in many fields.It is a challenge to design an anomaly detection method for a multi-dimensional sequence over the dataOn one hand, most existing methods of sequence anomaly detection focus on the single-dimension sequenceTo improve the performance of anomaly detection for a multi-dimensional sequence over the data streamdata stream, we propose a method called “random sampling and subsequence partitioning based on the index

This article focuses on the dynamic index and performance of a radial symmetric six-legged robot.A novel index of total torque is proposed by considering the posture of the supporting legs.The new index can be used to optimize the leg’s structure and operation for consuming minimum powerMain influences are outlined as well as the usefulness of the proposed performance index.
