<p>The invention relates to a brake rotor having improved damping characteristics and a method for producing the same. A surface of the brake rotor is EDG machined, also known as IDM machine, for improving the damping characteristics of the rotor. The decay rate of the brake rotor is increased and the Q factor of the brake rotor is reduced. The portion of the brake rotor which is EDG machined is formed of an electrically conductive material, preferably a ferrous material, more preferably a cast iron material, a gray iron material or a damped iron material. The brake rotor may include a solid friction section or a ventilated friction section. The brake rotor is preferably cast from a single material, although alternatively, it may be a composite rotor formed of more than one material.</p> |
