The principle of operation of force sensors most commonly used in machining processes and the trends of this technology are presented in this paper. Force sensors are needed because measuring cutting forces during machining processes is the most important and basic step to determine and control the conditions under which the machine, the tool, and the workpiece are performing. In the majority of applications the measurement of cutting forces during machining is done using dynamometers based on

Recently, micro-electro-mechanical systems (MEMS) are being designed and constructed using polysilicon beam resonators to measure forces. These sensors relate the force that is being measured to the frequency of vibration of the resonator. In recent research projects and studies, there is a tendency to transfer the force sensor signals by wireless technology. Ingeniería 11 (1,2):129-141, 2 001 San José. Costa Rica
