Design of Data Collection and Analysis System for a Three Dimensional Integrated Dynamometer on Turning

Cutting force is a key factor that reflects machining accuracy, tool life and machining efficiency. There is a close relationship between cutting force and chip formation, cutting heat and the vibration in cutting process. By measuring real-time cutting force, cutting condition is observed and the cutting parameters can be adjusted properly in time, which will in turn improve cutting efficiency, extend too life and decrease machining cost. An excellent data collection and analysis system is a key factor for precision measurement. In this paper, a kind of data collection and analysis system based on MCU STM32 for a three dimensional integrated dynamometer on turningis proposed. It has static calibration function, real-time acquisition function and data analysis function for three dimensional cutting force.
