Abrégé

A resin bonded super abrasive tool. The tool is manufactured using a liquid 3D light cured solution printer (3D printing which uses a liquid resin super abrasive and secondary fillers). The liquid resin is mixed with effective amounts of the super abrasive material and secondary fillers, and they are co-deposited and cured by printer during the 3D printing process.

A process for retruing a profile in an abrasive wheel is provided. A lathe table including an edged cutting tool is used for fixturing a grinding wheel having an outside metal edge and an abrasive matrix adjacent thereto for rotation along an axis compatible for lathe removal of material at at least the outside edge of said wheel. A predetermined amount of material along said edge with the edged lathe cutting tool is removed using the lathe cutting tool. A rotating electrical discharge profiling tool which is attached to an electrical discharge machine is used for profiling of the wheel by electrical discharge machining of the abrasive surface with the rotating electrode. The process uses a machine specifically designed for electrical discharge machining of the profile. The machine also has a mechanism cutting a predetermined profile into the electrode without removing it from the machine.

The present invention relates to a beveling wheel and method for forming a beveled lens with the beveling wheel for use with eyeglasses. One embodiment includes a prescription lens for use on an eyeglass frame having a receiving channel. The receiving channel includes a channel bottom and opposed interior wall surfaces having a first angle therebetween. The prescription plastic lens includes a prescription lens body generally defined by a peripheral edge having a bevel extending away from the edge to a vertex. The bevel has a distal portion with a second angle. The bevel is receivable within the receiving channel. At least a portion of the vertex of the bevel has an interference fit with the receiving channel bottom when held within the eyeglass frame. The first angle is greater than the second angle.

A segmented profiled wheel for grinding a glass or non-metallic workpiece including a segmented abrasive portion formed of a plurality of abrasive segments that are attached to a core of the wheel and method for making same. The plurality of abrasive segments have a cutting surface profile and sufficient abrasive grit to contour and grind the workpiece. Terminal ends of the plurality of abrasive segments are adjacent to one another and the cutting surface profiles align to form a substantially continuous rim of profiled abrasive segments for substantially continuous contact with a workpiece while the wheel rotates. The method includes the steps of forming the plurality of abrasive segments having a metal bonding matrix using automated processes, machining a metal blank to form a core, and attaching the plurality of abrasive segments to the core by laser welding and/or brazing.
