For the development of precision machinery, a limited number of well-known design principles apply. They include stiffness management, ‘weight watching’, kinematic design, and elimination of friction and backlash. A disadvantage of constructions designed in this way is a lack of damping. The Smart Disc concept uses piezoelectric sensors and actuators to actively dampen vibrations. The challenge in designing accurate, well-dampened machine frames lies in having the control technology – in itself not overly complicated – accepted as an established design principle.
