Abstract: A method and system design and manufacture of the monogrammed faceted and stone adorned eyeglass lenses via a computer program allowing a design, intricate facet cuts and stone placement on a computer lens model. Software may utilize a touch probe or laser scanner to gather point data from a previously designed lens, converting the data to a computer model. The data is then used to send signals to an articulated robotic arm holding a lens shape. The robotic arm receives the commands from the computer, moving and rotating the lens shape against an abrasive wheel, rotating cutter blade or rotating drill thereby duplicating the facet cuts, slots notches or depressions or other designs contained in the computer lens model. Varying pressure is applied by the articulated arm and various degrees of abrasiveness of the abrasive wheel.

Abstract: A flash removing method whereby flash is cut off by a reamer which is freely movable while being in contact with polymeric molded products within a predetermined range of pressing force. The reamer is provided with blades having normal clearance angles of substantially zero degree and the flanks of the blades follow the flash-forming region. The reamer is controlled in radial position according to the shape of the polymeric molded product, so that the reamer always receives a constant radial load from the product to leave even traces after the flash removal. A solidified gate is cut off before the flash removal. A flash removing apparatus for performing the method.

Abstract: The invention relates to an automatic machine for shaping spectacle lenses, especially those in shatterproof material, with a bevel that serves to hold the lens in the frame. Lenses are copied from a pattern by three cutters which correspond to the three types of conventional bevel in current use; a positioning device stations the lens opposite the cutter giving the requisite bevel. Further devices adjust the position of the bevel in relation to the outer edge of the lens, and ensure that it follows the curvature of the individual lens while remaining at the right distance from the edge. The machine is a copier, and as such, utilizes a tracing mechanism for reproduction from the pattern lens; cam control is adopted for scaling the size of the copied lens up or down in relation to the pattern.

Abstract: A machine for manufacturing a templet for edge grinding a spectacle lens according to the shape of an opening in a spectacle frame designed to hold the lens, comprises a spectacle frame holder supported on a housing. A copying sensor is mounted on the housing for rotation about the axis of the opening and for rectilinear displacement, the sensor sensing the shape of the opening upon rotation thereof. A blank holder is rotatable synchronously with the sensor and a sliding carriage is mounted on the housing for rectilinear displacement with respect to the blank holder, the sliding carriage carrying a cutting tool for cutting the blank to provide said templet. A plunger is rectilinearly displaceable with the copying sensor and synchronously controls the rectilinear displacement of the sliding carriage and cutting tool, the plunger having an axis extending in the direction of the axis of the spectacle frame opening.

Abstract: In a plastic lens grinding machine of the type having a head mounted on a base and adapted to carry a lens pattern and a plastic lens having a base curvature, the head is capable of movement parallel to the axis of rotation of the plastic lens. A carriage is mounted on the base and is movable perpendicular to said axis of rotation, with the carriage having an improved rotatable cutter with a cutting edge made of a metal of high hardness and adapted to be rotated at high speed in order to be self-coolant. A hydraulic damper is mounted on the carriage and connected to the base for regulating the gravitational movement of the carriage towards the axis of rotation of the plastic lens, thus regulating the engagement of the metallic cutter blade with the periphery of the plastic lens. An improved bevel aligning device is provided having a base curve cam connected to the head and a cam tracer connected to the carriage, with the cam having a surface forming the same base curvature as the plastic lens.
