It integrates mechanical design, sensor installation, electronics, and software to provide accurate, real-time signal force feedback. Aluminum was chosen for the structure due to its mechanical advantages, and four strain-gauge load cells arranged in an X-pattern ensure balanced force detection. The system uses an HX711 amplifier and Arduino Uno microcontroller, with a 16×2 LCD for live force display. Calibration with reference weights confirmed measurement reliability under various machining conditions. This approach offers a simple yet effective solution for monitoring cutting dynamics, essential for optimizing machining processes. Future enhancements may include vibration measurement and wireless data logging.enCutting force measurement- Low-cost device- Strain-gauge load cells- Arduino Uno -HX711 amplifier- Real-time monitoring- Mechanical design.Thesis
