The realtime evaluation of normal, tangential and perpendicular cutting forces and spindle vibration provides a simple measure of blade friction, wear performance, diamond-bond wear rate differences, blade stiffness and machine support. These observations can be used to evaluate and diagnose problems in diamond sawing that might inhibit use of high-grade diamond crystals.
