This paper describes a basic study to develop a sensor for detecting the cutting force in milling processes by utilizing the Villari effect of ferromagnetic material. The cutting force is detected using the three force components in the x, y, and z directions and torque. Basic experiments were conducted to quantitatively investigate the characteristics of the Villari effect, namely the change in the magnetic permeability caused by the force applied on the ferromagnetic material that can be detected as inductance change in the coil. The results clarified that magnetic permeability is proportional to the force applied on the material and depends on the direction of the force.
