Definitions

  • the invention relates to a method for producing a concave surface from a lens blank, according to the preamble of claim 1, and also includes tools for performing the method on brittle and hard plastic lens blanks.
  • the invention has for its object to propose a method of the type specified in the preamble of claim 1, with which, at high cutting performance, both brittle hard materials and plastic materials for producing all the concave surface shapes customary in spectacle lens optics, with the result of a uniform surface quality and short machining times can be processed economically.
  • the task of the invention also includes the provision of tools which are particularly suitable for carrying out the method.
  • the object is achieved by the features of claim 1.
  • Advantageous further developments of the method are specified in subclaims 2 to 5 and are also explained in more detail below.
  • Tools which are particularly suitable for carrying out the process are specified in claims 6 and 7, of which claim 6 includes the tool design for brittle hard materials and claim 7 the tool design for plastic materials.
  • the continuous piercing or immersion process saves the multiple cuts required in the known method in the case of thick spectacle lens blanks.
  • a surface is achieved at least in the area of the outer edge which corresponds to the nominal outer contour of the optically effective inner surface of the spectacle lens.
  • the method according to the invention enables the generation of highly precise surfaces. It can be used to produce all the surface shapes that are customary in spectacle lens optics, namely toric, prismatic, decentered, multifocal or atoric surfaces on glasses and plastics.
  • An edge processing operation is preferably integrated in the method according to the invention, as a result of which not only can thin, comfortable spectacle lenses be produced, but also a reduction in working time with less tool wear on the side of the spectacle manufacturer for the later fitting of the spectacle lens.
  • the advantage for the process user is that a smaller stock of semi-finished glasses with different diameters is made possible.
  • edge machining, grooving and machining along the spiral path according to claim 3 are carried out in a continuous sequence, very short manufacturing times can be achieved. These operations can be carried out in a single clamping or blocking of the workpiece.
  • a faceting operation can also be switched on in the process sequence, so that when an edge processing operation is carried out, a total of four immediately successive operations are carried out on the workpiece with only one clamping or blocking.
  • a fixed angle between 90 ° and 120 ° is possible between the two rotational movement axes c and b.
  • this angle is set at 105 ° according to claim 5, i.e. with the workpiece axis b arranged vertically, the tool axis c is inclined to the horizontal at an angle of only 15 °. At this angle, there can be no collision between the tool spindle or the tool shaft and the rim of the lens while the grinding or milling process is being carried out, even with very strongly concave curved lens surfaces.
  • the grinding tool specified in claim 6 for performing the method on a brittle hard lens blank is very advantageous due to the special design of the grinding lip, because the cutting edge geometry remains constant even when worn. Only the diameter of the tool decreases due to wear, but this can easily be compensated for by measuring the thickness of the ground spectacle lens and subsequent calculation in the control program.
  • the milling tool according to claim 7 for performing the method on a plastic spectacle lens blank is disc-shaped in terms of its rotational shape, with individual milling cutting edges are distributed around the circumference.
  • the cutting performance of this milling tool, in which the cutting edges define a shaping toric envelope, is high.
  • the service life of the milling cutters can advantageously be increased if the cutting plates of the milling tool having the cutting edges are rotatably fastened in accordance with claim 8. In this way, several areas of the cutting inserts can be screwed into a working position before the cutting inserts are replaced for reasons of wear or their outer diameter has to be reworked.
  • FIGS. 1 and 2 Of the grinding or milling machine, only the parts 1 and 2 carrying or guiding and driving parts are shown in FIGS. 1 and 2 for simplification.
  • the tool 2 is attached via a shaft 3 coaxially to a spindle 4, which is driven by an electric motor 5 so that it can be rotated and its speed can be regulated.
  • the workpiece 1 is blocked on a workpiece holder 6, which is concentrically attached to a spindle 7.
  • the spindle 7 is driven by a servo motor 8 in a numerically controlled manner.
  • Workpiece 1, tool holder 6, spindle 7 and motor 8 as well as all associated parts not specified in more detail are attached to a coordinate device of the machine and can therefore be moved together on mutually perpendicular linear movement axes x and y.
  • the common central axis of the parts 1, 6, 7 and 8 coincides with the rotational movement axis b of the workpiece 1.
  • the central axis common to the tool 2, the shank 3, the spindle 4 and the motor 5 coincides with the rotational movement axis c of the tool 2 and a tool setting axis z (FIG. 1).
  • the linear movement axes x, y and the rotation movement axis b are CNC-controlled, while the rotation movement axis c can only be regulated by speed.
  • the axis z is only used for the adjustment of the tool 2 on the rotational movement axis c. Since all CNC axes are combined in the workpiece spindle, simple loading results. The workpiece can be moved into a defined loading and unloading position, so that simple handling devices can also be used for automatic workpiece change.
  • the angle ⁇ defined by the machine construction between the two rotational movement axes b and c has the value of 105 °.
  • the angle ⁇ is thus determined by the machine construction and cannot be changed.
  • the tool spindle 4 with the attached tool 2 and the associated electric motor 5 and all other associated unspecified parts can be adjusted while maintaining the design angle ⁇ for adjusting the tool 2 to the center of the workpiece 1 at right angles to the x-movement axis.
  • the aforementioned adjustable parts are rigidly connected via a support arm 9 to a guide carriage 10 which is mounted on a guide bed 11 of the machine so as to be displaceable in the specified direction of adjustment.
  • a threaded spindle 12 is effective for adjustment, which on the one hand is rotatable but axially immovable on the guide bed 11 is mounted and on the other hand engages in a corresponding thread of the guide carriage 10.
  • the grinding tool is disc-shaped with an annular grinding lip 13 located on its circumference. Starting from the end face of the asymmetrically designed grinding lip 13, its radius increases towards the spindle 4, its largest radius ending in a circular shaping cutting edge 14. To carry out the method, this shaping cutting edge must be set on the workpiece such that it is directed approximately radially to the center of the workpiece.
  • the rear surface 15 of the grinding lip 13, which ends in the cutting edge 14 and is located on the spindle side, is designed taking into account the constructively defined angle ⁇ such that the rear surface to the tool rotation axis c runs at the angle ⁇ .
  • a perpendicular through the lowest point 16 of the cutting edge 14 lies against the rear surface 15 in the manner of a radial surface line.
  • the lowest point 16 is always in the plane of the two linear axes of movement x and y. This becomes clear when comparing FIGS. 3 and 4.
  • the cutting edge 14 is always determined by the largest radius of the grinding lip and is always directed approximately radially to the center of the workpiece even as tool wear progresses. In addition to the wear contour shown in full lines, the new contour of the tool is also shown in dashed lines in FIG. 4. Due to this special tool geometry, the cutting edge always sharpens itself during the grinding process, so that the shape of the surface to be machined is not impaired. The reduction in the cutting edge radius due to wear can easily be taken into account in the computer program of the machine.
  • the grinding material of the grinding lip 13 consists of finely divided diamond particles.
  • the grinding lip 13 consists either of sintered material, in which the diamond particles are embedded in a finely divided form, or the finely divided diamond particles are applied to the annular grinding lip 13 in a galvanically bonded manner.
  • the milling tool 2 ' is disc-shaped with respect to its rotational shape.
  • the milling tool 2 ' is provided with a plurality, in the example shown with eight holding arms 17 which are evenly distributed on the circumference and which extend outwards from a central hub part 18.
  • the annular cutting edges 20 of the cutting inserts 19 are aligned radially to the axis of rotation c of the milling tool 2 'and define a shaping toric envelope surface, which is indicated by broken lines in FIG. 5.
  • the toric envelope surface is oriented approximately radially to the center of the workpiece with respect to its plane formed by its largest radius.
  • the deepest point 16 'of the shaping toric envelope is always in the plane of the two linear axes of movement x and y.
  • Fig. 6 it is shown that the cutting plates 19 are each fastened to the holding arms 17 by a central screw 21. With the help of the screw 21, the set rotational position of the cutting insert 19 is fixed on the holding arm 17. As indicated in Fig. 6 by the angle dimension ⁇ , only an angle of about 90 ° is used from the circular circumference of the ring cutting edge 20 for the milling process, i.e. only about a quarter of the circumference of the ring cutting edge is used for the milling process. This means that the cutting inserts 19 can be rotated three times into a new position after the first ring cutting sector has worn out.
  • FIGS. 8 to 11 This process sequence covers all possible machining operations, namely the edge machining operation (FIG. 8), the faceting operation (FIG. 9), the plunge operation (FIG. 10) and the surface processing Final step in the context of the present method with machining along the spiral path (FIG. 11).
  • the relative movement of the tool center relative to the workpiece is indicated in dotted lines. In fact, it is not the tool that is moving relative to the workpiece, but the other way round, the workpiece is moving relative to the tool.
  • the blocked workpiece 1 is first approximated to the tool 2 by lateral displacement on the x-axis, whereupon the workpiece 1 is displaced on the y-axis relative to the tool 2 which always remains stationary until the workpiece 1 is approximately at the same height as the tool axis is located and the workpiece edge tangent to the circular cutting edge 14.
  • material is removed from the workpiece edge.
  • processing of the spectacle lens blank is now carried out to the circumferential contour predetermined by the shape of the spectacle frame.
  • the tool is attacked at the edge of the workpiece approximately in the manner of a helix.
  • the upper workpiece peripheral edge is faceted using the tool.
  • This process takes place in a continuous sequence with the others Work steps with constant rotation of workpiece and tool.
  • the workpiece 1 is both approximated to the tool 2 on the x-axis and the workpiece is moved downward in a movement overlaid on the y-axis until the desired facet surface 22 is achieved .
  • the workpiece 1 is moved relative to the tool 2 during the plunge-in operation by means of coordinated, program-controlled movement on the x and y axes with constant rotation of the workpiece and tool about the associated rotation axes until the tool and workpiece are roughly the same as in FIG 10 take the relative position shown.
  • the bulk of the blank material to be removed is removed. This has resulted in an annular trough-shaped surface 23 which is adapted as far as possible to the surface to be produced.
  • an outer edge 24 is achieved, which corresponds to the target outer contour of the optically effective inner lens surface. This completes the grooving process.
  • the last work step illustrated in FIG. 11 takes place, which serves to remove the remaining amount of the excess blank material until the surface is finally shaped.
  • a superimposed movement takes place between the workpiece 1 rotating about its axis b and the otherwise stationary tool 2 rotating about its axis c in the direction of the x and y axes with a spiral course of the machining path 25 shown in FIG. 12 on the machined surface .
  • the annular trough-shaped surface resulting from the plunge-in work process disappears, ie the approximately conical central tip of this surface.
  • a method for producing a surface from an eyeglass lens blank is described which is suitable for brittle hard materials as well as for plastics.
  • a disk-shaped, rotationally symmetrical tool of relatively large diameter is used, with the aid of which the blank material to be removed is removed with a high grinding or milling capacity in at least two work steps, a plunge-cutting step and a shaping step with material removal along a spiral path.
  • the last operation results in a machining path running spirally from the outside inwards with a low residual tip height and a relatively large tip spacing.
  • the surface created requires only minor fine grinding and polishing post-processing.
  • both an edge machining process that adapts to the shape of the spectacle frame and a work step that facets the rim of the spectacle lens can be integrated into the method. Tools for carrying out the grinding or milling process are also proposed.
