Design and Simulation of Completely Centered Integrated 3D Cutting Force Sensor Based on Decagonal Ring

The cutting forces during cutting can visually reflect various conditions of the cutting process, such as tool wear and workpiece machining. Based on the decagonal ring, a fully aligned integrated cutting force sensor is designed, and a calibration collet is designed for the calibration of the 3D force, and the sensor is encapsulated. The sensor and the calibration collet are calibrated by finite element software, and the first six orders of inherent frequencies and modal vibration patterns are calculated by modal analysis. Full-scale loading of the sensor in three directions for several times, found that the sensor initial output did not change, indicating that the sensor design meets the strength requirements.
