An upper shield and a lower shield may be coupled to a rotor for polishing airfoils of the rotor in a vibratory bowl. The upper shield and the lower shield may include spars. The spars may correspond to leading edges and trailing edges of the airfoils. A media including abrasive particles may be flowed through the rotor in the vibratory bowl. The spars may protect the leading edges and trailing edges of the airfoils from excessive material removal by the abrasive particles.

In a method of monitoring a vibratory grinding process, parameters from different parameter groups are detected and evaluated to output a command for operating the vibratory grinding system.

An invention is provided for creating smoothed, heat-treated glass fragments. The invention includes placing a plurality of heat-treated glass fragments into a tumbling or vibrating apparatus. Each heat-treated glass fragment is formed from glass that has been heated to a temperature of at least 1000° Fahrenheit and rapidly cooled to a temperature below 800° Fahrenheit. The plurality of glass fragments is then tumbled or vibrated for a predetermined period of time such that surfaces of the heat-treated glass fragments are smoother than prior to tumbling. The glass fragments are thereafter removed from the tumbling apparatus, resulting in smoothed, heat-treated glass fragments that have a slightly rounded, bead like-shape and are suitable for direct handling without hand protection. The glass fragments as are able to be provide radiant heat in the temperature range of 400° to 800° Fahrenheit. This temperature range and the use of the heat-treated glass fragments provides for a clean burning fire that virtually eliminates any soot and carbon monoxide while burning.

A method for modifying the mechanical and surface properties of a component. The method involves: removably attaching a component to at least one component support that is located within a vibratory trough of a component treatment apparatus, the at least one component support being a support shaft upon which the component is removably mountable within the vibratory trough; supplying the vibratory trough with treatment media; moving the component support or the vibratory trough so that the component is immersed into the treatment media; vibrating the vibratory trough to provide a substantially uniform surface treatment of the component, the vibratory trough being movable by at least one trough vibrating mechanism whose actuation is controlled by a controller in response to signals received from at least one sensor located on or within the vibratory trough; removing the component from the treatment media; and detaching the component from the component support.
