An abrading system is presented. The system includes a first vibratory structure comprising a first plurality of protrusions. The system also includes a second vibratory structure comprising a second plurality of protrusions. The system also includes an abrasive article contacting the first film. The system also includes a stroke plate coupled to the second film. When the stroke plate is activated, the first and second plurality of protrusions are configured to interlock and slip with respect to each other in a first direction.

A method of manufacturing a grinding wheel includes a surface unevenness forming step of applying ultrasonic vibrations from an ultrasonic vibration applying unit through water to an annular slot defined in a surface of an annular base along circumferential directions thereof, thereby forming surface unevennesses on either one or both of a side surface and a bottom surface of the annular slot, and, after the surface unevenness forming step, a grindstone fixing step of fixing a plurality of grindstones to the annular slot with an adhesive.

An apparatus comprises a stressed glass member and an actuator mounted on the stressed glass member. A power source is coupled to the actuator. An abrasion structure is disposed between the actuator and the stressed glass member. The abrasion structure comprises abrading features in contact with the stressed glass member. The abrading features have a hardness higher than a hardness of the stressed glass member. When energized by the power source, the actuator is configured to induce movement of the abrasion structure that causes the abrading features to create scratches in the stressed glass member to a depth sufficient to initiate fracture of the stressed glass member.
