摘要： A lens surface cutting method for a spectacle lens includes the steps of calculating the mean curvature of a lens surface (5) to be machined, calculating a helical machining path (4) that matches the mean curvature, and cutting the lens surface (5) to be machined by a cutting means. The helical machining path (4) calculated by the helical machining path calculating step is a path in which helix spacings P (=P1, P2, . . . Pn) on the lens surface (5) to be machined are equidistant and a helix spacing d (=d1, d2, . . . dn) on an X-Y projection plane 100 increases continuously from a lens outer periphery toward a center. The cutting means cuts the lens surface (5) to be machined from the outer periphery toward the center along the helical machining path (4). Thus, a spectacle lens having a lens surface with a surface accuracy that is almost uniform throughout an entire surface can be obtained.

摘要： The present invention relates to a method of manufacturing a lens casting mold in which an upper surface of a glass material being formed is formed into a shape of a molding surface for forming a surface comprising a progressive surface or a progressive element by using a continuous heating furnace. As the forming mold, a forming mold having a curvature distribution on the forming surface is utilized. In one aspect, a temperature of the continuous heating furnace is controlled so that the continuous heating furnace comprises a temperature rising region having a temperature distribution such that the temperature rises in a conveyance direction of the forming mold, and a separation distance between the forming surface of the forming mold and a lower surface of the glass material being formed is specified in two or more spots before introduction to the continuous heating furnace. The forming mold is conveyed in the temperature rising region so that a portion with the greatest separation distance among the specified separation distances is comprised in a portion on a side of the conveyance direction as divided in two by a virtual line, the virtual line running orthogonally to the conveyance direction of the forming mold and passing through a geometric center of the forming surface. In another aspect, a forming mold position control region is provided in the continuous heating furnace, a temperature is directly or indirectly measured at multiple measurement points on the forming surface in the forming mold position control region, and the forming mold is conveyed so that a portion on the forming surface of greatest curvature is present in a high temperature portion that has been determined based on the measurement result. A virtual line A passing through a geometric center and a maximum temperature point among the multiple measurement points is specified, and then a portion containing the maximum temperature point as divided in two by a virtual line B running orthogonally to the virtual line A and passing through the geometric center is determined as the high temperature portion.

摘要： An aspect of the present invention relates to a method of manufacturing a formed article forming an upper surface of a forming material comprised of a thermosoftening substance into a desired shape by heating the forming material in a state where the forming material is positioned on a forming surface of a forming mold to a temperature permitting deformation of the forming material to bring a lower surface of the forming material into tight contact with the forming surface. The heating is conducted by positioning the forming mold, on which the forming material has been positioned, beneath heat source(s) radiating radiant heat in a state where a plate-shaped member the outermost surface of which is comprised of a metal material is positioned above the upper surface of the forming material. Another aspect of the present invention relates to a method of manufacturing a formed article forming an upper surface of a forming material comprised of a thermosoftening substance into a desired shape by heating the forming material within a heating furnace in a state where the forming material is positioned on a forming surface of a forming mold to a temperature permitting deformation of the forming material to bring a lower surface of the forming material into tight contact with the forming surface. The forming is conducted while an exposed portion on the forming surface side of the forming mold on which the forming material has been positioned is covered with a covering member, and at least a portion of the covering member comprises a metal material layer.
