Intelligent cutting tool system for precision cutting, characterized by comprising a cutting blade, a top shaft, a bottom shaft, a pressure sensor, a Bluetooth transmission device and a power supply device, where the pressure sensor, through the Bluetooth transmission device, includes the real-time data the CNC machine tool system transmits power to the pressure sensor and the Bluetooth transmission device;and where the upper shaft is divided into a pressure sensor section and a fixed connection section fixed to the lower shaft; and where at the front end of the pressure sensor section a blade mounting point aligned to the cutting blade is provided, and where the cutting edge of the cutting blade is located at the centre line of the cross-section of the main body of the upper shaft after the cutting blade has been installed in the blade installation nut;and where a pressure sensor is located on the left side of the pressure sensor section and the pressure sensor is positioned in the pressure sensor angle and the pressure sensor is in a state of pressure voltage and measures a radial force in the horizontal direction, if the radial force acts on the cutting blade in the horizontal direction;and where a pressure detection column is provided between the pressure sensor section and the lower shaft, and where the pressure sensor is also located in the pressure detection column, which is fixed by the pressure voltage of the connection between the upper shaft and the lower shaft and for measuring the main cutting force in the vertical shaft; direction is used;and with a removable support block located on both sides of the column, which is used in the pressure detection column to change the support point of the pressure sensor section.
