High performance machine tools feature rapid traverse rates of 1,200 inches per minute. Linear motor servos and low inertia designs can double or triple those feedrates. Perhaps more important than high feedrate capability, is high acceleration and deceleration. Conventional machining centers achieve 0.2 g's. High performance systems start around 0.5 g's and go as high as 4.0 g's. At that rate, the forces of acceleration exceed cutting forces. Therefore, design optimization becomes critical. The goal is to achieve maximum stiffness with minimum inertia.
