IMU 데이터를 활용한 이동 정확도 및 정밀도 분석
Abstract
Accurate movement measurement is essential in precision manufacturing to ensure high-quality production. This study presents an IMU-based system for evaluating movement accuracy and precision in CNC-based electrochemical machining. The system employs an IMU sensor attached to the moving electrode to measure displacement along the X and Y axes, verifying whether the commanded travel distance (e.g., 1 mm) matches the actual movement. Unlike traditional monitoring methods that rely on indirect sensor-based measurements requiring mechanical error compensation, this approach directly analyzes movement accuracy using real-time IMU data. To achieve this, displacement data from the IMU is collected and processed in MATLAB, where filtering and noise reduction techniques enhance measurement reliability. Experimental validation demonstrates the system’s ability to detect small-scale motion deviations, offering a quantitative assessment of movement errors. The proposed method provides a practical solution for real-time displacement verification in high-precision machining, contributing to improved process efficiency and quality control.
