With the rapid development of high precision machining, there is a need to monitor certain parameters in the machining processes so as to detect tool wear and optimize cutting parameters. In this paper, the use of surface acoustic waves (SAW) sensors for potential application to precision machining processes is presented. The working principle for such an application has been demonstrated through FEA simulation in order to detect its modal frequency and modal shape. For the experimental implementation, two SAW strain sensors are mounted onto two AL plates bolted on top and bottom of the cutting tool shank respectively, in order measure the cutting force in a real machining environment.
