Definitions
- the invention relates to a device for polishing an optical surface, having a polishing head, the polishing tool of which has a first, preferably rigid body, a second, elastic body and a polishing pad along a common axis, each of which extends essentially radially to the axis ,
- the invention further relates to a method for polishing an optical surface.
- the invention further relates to an optical component.
- the invention relates to a method for producing a polishing tool which, along a common axis, has a first, preferably rigid body, a second, elastic body and a polishing covering, which each extend essentially radially to the axis.
- optical surfaces when used in the context of the present invention, all surfaces of optical components are meant such as surfaces, in particular aspherical surfaces or free-form surfaces, of spectacle lenses, mirrors, plastic optics, etc.
- Spectacle lenses are usually manufactured from a blank by machining the so-called prescription surface or surfaces. This defines the optically relevant shape of the lens. Finally, the eyeglass lens is polished, which, however, should no longer cause any noticeable change in the optical properties.
- a polishing head which is a polishing tool, is usually used to polish a surface of a spectacle lens has, whose polishing surface is at least approximately adapted to the shape of the surface of the spectacle lens to be polished.
- the polishing tool and / or the spectacle lens are articulated, in particular with a ball joint, and are guided relative to one another with a predetermined movement sequence, usually with the aid of multi-axis robots.
- polishing spherical or toric lenses it is less problematic due to the relatively simple shape of the surface to be polished, to find a suitable, complementarily designed polishing tool that can be moved over the surface with simple movements and does not cause any inadmissible deformations there. Due to the large number of possible spherical or toric glasses, it is only necessary to have a corresponding large number of polishing tools.
- a polishing body that is always rigid is used, which is unchangeably adapted to the shape of the surface to be polished and can therefore only be used for this surface.
- a polishing body which is rigid in use, but which can first be put into a plastic state, for example by heating, so that it first settles in can adapt this plastic state to any surface before it solidifies.
- polishing tools are rigid in use and can therefore only be used for polishing regularly shaped surfaces.
- a polishing body which can also be deformable during use. This deformability is achieved by a bundle of parallel metallic rods, which are supported at one end on an elastic membrane and can be moved individually. The total area formed by its end face at the other end adapts to the shape of the surface to be polished.
- polishing tools like every membrane, has an elasticity curve in which the center is the softest point and the elasticity decreases radially outwards, i.e. the membrane becomes stiffer towards the edge or the spring characteristic curve becomes steeper. As has been established in the context of the present invention, this is disadvantageous for polishing tools of the type of interest here, because this course of elasticity causes greater shape defects.
- a further disadvantage of these polishing tools is that the movement of the bars is associated with mechanical friction, so that dynamic polishing processes can hardly be implemented.
- polishing bodies are per used, which have a directly pneumatically deformable polishing body.
- the disadvantage of an unfavorable elasticity curve described above also arises here.
- the body has a body made of elastic material between a rigid one Carrier body and the polishing pad arranged.
- the axial thickness of the elastic body is constant in the known polishing tools and the material of the elastic body is homogeneous.
- the elasticity is therefore constant in the radial direction.
- polishing tool is usually CNC-guided over the surface of the spectacle lens to be polished.
- the polishing head usually drives the polishing tool at the same time and presses it against the surface to be polished.
- Aspherical or point-asymmetrical free-form surfaces have curvatures that change above the surface.
- the polishing tool moves over at least part of this irregularly curved surface during the polishing process. Its elasticity must therefore be able to adapt to the respective local curvature, in such a way that the polishing pressure is as constant as possible across the contact surface. Only then will there be a predeterminable, constant removal and the polished surface will be optimally smooth. If this cannot be guaranteed and the polishing pressure fluctuates across the contact surface, the desired aspherical surface topography is deformed and consequently its optical quality is deteriorated. Such deformations occur with known polishing tools in conventional production processes and therefore have to be compensated step by step with iterative finishing processes. However, this is time-consuming and costly.
- the grinding head has a base body coated with grinding material, which consists of a soft, extremely yielding material, for example of foam rubber.
- the grinding head is mushroom, cone or spherical in axial section, so that it is thinner in the edge area than in the middle. This makes it harder in the edge area.
- a similar grinding head is also disclosed in US 3,043,065. This known grinding head is mushroom-shaped and therefore also harder in the edge area than in the middle.
- the invention is therefore based on the object of developing a device, method and an optical component, in particular a spectacle lens of the type mentioned at the outset, in such a way that these disadvantages are avoided.
- this object is achieved according to the invention in that the second body is made increasingly softer in the radial direction from the inside to the outside.
- this object is achieved according to the invention in that a device of the type mentioned above is used.
- this object is achieved according to the invention in that it has been produced by the method mentioned above.
- this object is achieved according to the invention in that the second body is made increasingly softer in the radial direction from the inside to the outside.
- the invention provides an incredibly simple polishing tool that is similar in structure to known polishing tools, but due to its design, in contrast to conventional polishing tools, it is also able to grind irregularly curved free-form surfaces on spectacle lenses without an irregular removal occurring during polishing. This is achieved by deliberately influencing the elasticity of the elastic body carrying the polishing layer in the radial direction, in that the elastic body is made softer in the radial direction from the inside to the outside, that is to say it has an increasingly flatter spring characteristic.
- the second body is continuously softer in the radial direction to the outside.
- the second body can also be discontinuously softer in the radial direction to the outside.
- the second body has an increasing axial thickness in the radial direction.
- This measure has the advantage that the desired radial stiffness profile can be set almost arbitrarily if the radial profile is predefined in accordance with the axial thickness. In this way, the tool can be optimized very sensitively.
- the second body borders with an inner contour on the first body and with an outer contour on the polishing pad, the course of the axial thickness over the radial direction being determined as a function of the radial course of the contours.
- This measure has the advantage that optimization with two contours is possible, so that the outer contour can be adapted particularly well to the surface to be polished and essentially the inner contour can be used to set the desired radial profile.
- the inner contour can be convex and the outer contour convex, or the inner contour convex and the outer contour flat, or the inner contour concave and the outer contour concave, or the inner contour flat and the outer contour concave, or the inner contour convex and the outer contour concave.
- the outer contour is spherical or aspherical or as a free-form surface.
- the second body consists of a material whose modulus of elasticity is greater than 0.02 N / mm 2 .
- the selection of materials for the second body it is preferred if this is selected from the group rubber, rubber, polyurethane, polyether urethane, elastomer.
- the second body is a cast part.
- a further embodiment of the invention is characterized in that the second body is formed from a material whose elasticity increases in the radial direction from the inside out, i.e. the compression spring characteristic curve becomes increasingly flatter from the inside out.
- the second body has the advantage that the shape of the second body is free within wide limits.
- the second body can therefore also be made with a constant thickness, that is to say in the form of a circular disk, but because of the special, inhomogeneous one
- the nature of the material nevertheless has the desired radial profile of elasticity, in which the second body is radially softer on the outside than on the inside.
- the second body can advantageously have a constant axial thickness in the radial direction.
- polishing surface any structure that can represent a polishing surface.
- the polishing covering can advantageously only be a polishing paste, or it is physically designed as a polishing membrane, polishing pad or polishing layer material.
- the present invention preferably relates to the polishing of surfaces of spectacle lenses or mirrors or aspherical mirrors or aspherical optical surfaces.
- the polishing tool can either be round or out of round with respect to the axis. It can also be articulated either in the axis or outside the axis.
- the second body is produced in the radial direction with increasing axial thickness, the second body being produced with an inner contour adjacent to the first body and with an outer contour adjacent to the polishing layer and the course the axial thickness over the radial direction is determined depending on the radial course of the contours.
- the first variant is characterized by the following steps: a) determining a desired average polishing pressure pm of the polishing tool; b) determining the necessary contact pressure Fk from the polishing surface of the polishing tool; c) selecting an elastic modulus E for the material of the second body; d) selecting a center thickness Di of the second body; e) selecting an initial outer contour; f) calculating an average deflection depth di for a second body, assuming that the second body has a constant axial thickness D that is equal to the selected center thickness Di; g) determining a polishing movement of the polishing tool on the surface to be polished;
- the second variant is characterized by the following steps: a) determining a desired average polishing pressure pm of the polishing tool; b) determining the necessary contact pressure Fk from the polishing surface of the polishing tool; c) selecting an elastic modulus E for the material of the second body; d) selecting a center thickness Di of the second body; e) selecting an initial outer contour; f) calculating an average deflection depth di for a second body, assuming that the second body has a constant axial thickness D that is equal to the selected center thickness Di; g) determining a polishing movement of the polishing tool on the surface to be polished;
- FIG. 1 shows a schematic side view, partially broken away, of an exemplary embodiment of a polishing head according to the invention for polishing a surface of a spectacle lens;
- FIG. 2 shows an even more schematic representation of a polishing tool as used in the polishing head according to FIG. 1;
- FIG. 3 shows a representation, similar to FIG. 2, of a first variant of the polishing tool
- 4 shows a representation, similar to FIG. 2, of a second variant of the polishing tool
- FIG. 5 shows a representation, similar to FIG. 2, of a third variant of the polishing tool
- FIG. 6 shows a representation, similar to FIG. 2, of a fourth variant of the polishing tool
- FIG. 7 shows a block diagram to explain an embodiment of a method according to the invention for producing a polishing tool.
- FIG. 1 10 as a whole designates a device for polishing an eyeglass lens 12.
- eyeglass lens application is only to be understood as an example, because the invention can be used in general for optical surfaces.
- the spectacle lens 12 is held by a conventional holder 14, and in the example shown it is fixed in space.
- a first axis is designated by 15. This is both the geometric axis of the body of the spectacle lens 12 and the vertical axis of the holder 14.
- the spectacle lens has an inner, rear surface 16 and an outer, front surface 18.
- the inner surface 16 is the so-called recipe surface, which is optically processed in a predetermined manner and in particular is designed as a free-form surface.
- a polishing head 20 carries a polishing tool 22 at its free end.
- the polishing tool 22 has a first, preferably rigid body 24 in the form of a shell.
- a second, elastic body 26 adjoins this, which is also referred to as a buffer.
- the polishing pad 28 can only consist of an applied polishing paste or can be a separate physical structure, e.g. a polishing membrane, a polishing pad or a polishing layer material.
- the back of the first body 24 is provided with a ball socket 30 or another suitable joint part, into which a ball head 32 of an actuator of a polishing robot (not shown) symbolized with 34 engages, which extends along a second axis 36.
- the joint indicated in this way permits swiveling movements of the polishing tool 22 relative to the spectacle lens, but at the same time enables the polishing tool 22 to be rotated about the second axis 36. It is thus possible to drive the polishing tool 22 and to guide it with the polishing coating 28 over the surface 16 of the spectacle lens 12 to be polished, as is known to the person skilled in the art.
- the second, elastic body 26 is preferably made of rubber or rubber. It can also consist of a polyurethane material, for example polyurethane, polyether urethane or an elastomer. Such materials are known and for example under the trade names Sylomer, Sylodyn and Sylodamp von der Getzner available.
- the elastic modulus E of this material should be greater than 0.02 N / mm 2 .
- the elements 24, 26 and 28 sit closely next to one another in the direction of the second axis 36 and extend essentially in the radial direction. As will be explained, a distinction is made in the context of the present invention between round and non-round polishing tools 22.
- the second axis 36 does not necessarily have to be arranged in the center of the polishing tool 22.
- the present invention also includes other eccentric or tumbling embodiments.
- the polishing tool 22 is shown again schematically with the three elements 24, 26 and 28. It is important in this exemplary embodiment that the second body 26 has an axial thickness D that changes with the distance from the axis 36. This is because the elasticity of the second body 26 is to increase in the radial direction from the inside to the outside in a predetermined manner, ie with a predetermined profile. This means that the second, elastic body becomes softer on the outside, i.e. has an increasingly flat spring characteristic.
- an elastic plate material has a spring characteristic, i.e. a dependence of the pressure (N / mm 2 ) on the deflection (mm), which is flatter the thicker the plate material.
- the applied polishing pressure corresponds to the pressure.
- the axial thickness D already mentioned is measured between the contours 40 and 42.
- the desired increasing elasticity towards the edge of the polishing tool can alternatively also be achieved by using a material for the second body, the elasticity of which is not homogeneous but increases towards the outside. One is then largely free in the course of the axial thickness depending on the radial distance from the axis.
- the radial increase in elasticity towards the edge of the polishing tool can be adjusted continuously or in steps.
- the direction of the second axis 36 is denoted by z.
- the radial distance from the second axis is one-dimensional in the case of round polishing tools 22, that is to say h.
- it is two-dimensional, that is to say it is expressed in coordinates x, y.
- FIG. 2 further shows that the second body 26 is delimited on its upper side by an inner contour 40 and on its underside by an outer contour 42.
- the outer contour 42 is essentially the same as the envelope of the contour of the surface 16 to be polished.
- the inner contour 40 is concave and the outer contour 42 is convex.
- FIGS. 3 to 6 show variants of FIG. 2, the same elements being provided with the same reference symbols and being differentiated only by adding a letter.
- the inner contour 40b and the outer contour 42b are concave.
- the inner contour 40c is flat and the outer contour 42c is concave.
- the inner contour 40d is convex and the outer contour 42d is concave.
- the polishing tool 22 is pressed against the surface 16 of the spectacle lens 12 to be polished with a pressing force Fk.
- Fk a pressing force
- This model provides a one-dimensional relationship between the polishing pressure p (h) or the surface pressure for round or p (x, y) for non-round polishing tools 22 and the thickness D (h) or D (x, y) of the second body 26 represents:
- a first step (block 50), the desired average polishing pressure pm or the surface pressure in N / mm 2 is determined.
- the necessary contact pressure Fk in N is determined from the dimensions of the polishing tool 22, that is to say from the size of the contact area.
- a third step (block 54), the elasticity module E of the material for the second body 26 is selected in N / mm 2 and its center thickness Di is determined.
- a fourth step (block 56), the outer contour 42 of the second body 26 is established on the surface 16 starting from a basic position of the polishing tool 22.
- a fifth step (block 58) the average deflection depth di for a second body 26 with an assumed constant thickness Di is calculated according to the specification of the third step (block 54) using the following formula:
- a sixth step (block 60), the polishing movement of the polishing tool 22 on the surface 16 to be polished is determined.
- this polishing movement is discretized in a sufficiently large number n of small movement increments.
- the deviations in the z-direction become z_D (h) or z_D (x, y) between the outer contour 42 of the second body 26 that is shifted and / or rotated relative to the surface 16 to be polished, at one position i calculated. This is the local deflection area.
- a ninth step (block 66), these deviations z_D (h) or z_D (x, y) are added at all intermediate incremental positions. This is done component by component in the respective polar or Cartesian system.
- a tenth step (block 68) the minimum deflection depth z_Dmin is recorded, and accordingly in an eleventh step (block 69) the maximum deflection depth z_Dmax.
- a twelfth step (block 76) the tilt and the central offset of the averaged aspherical deformation surface are finally subtracted, and a value z_Dmt is obtained.
- the required iterations take place via the loops 74, 78 and 80.
- the value z_Dmt can then be used to continue working according to two different variants A and B, which are identified in blocks 84 and 86 with the associated equations IV to IX or X to XIII.
- variant A the outer contour 42 is first corrected by the value z_Dmt in order to compensate for the averaged deflection deviations, specifically for round polishing tools 22:
- K2 (x, y) K2 (x, y) + z_Dmt (x, y)
- Variant A thus completely compensates for the mean dynamic spring deviation and reduces the dynamic spring pressure deviation by the function of the thickness D of the second body 26.
- the inner contour 41 here called Kl
- the factor f_a is used as a special factor assigned to the aspherical type.
- the factor can ideally be between 1/2 and 2.
- the dynamic spring pressure variations are not compensated for in this variant.
- the second body 26 is designed for machining a toric aspherical surface of a spectacle lens according to variant B.
- a base radius RB of 150 mm with a refractive index of 1.6 means a refractive index of 4 diopters.
- a cylinder radius RZ of 100 mm means a refractive index of 6 diopters with the same refractive index.
- Such an aspherical toric surface therefore represents a cylindrical refractive index of 2 diopters.
- Over 90% of all spectacle lenses have a cylindrical effect of less than 2 diopters.
- the asphericity of the described torus is approximately 900 ⁇ m in the 45 mm diameter range.
- the center thickness Di of the second body 26 is 4 mm.
- Example 1 (prior art) The polishing tool 22 is pressed in a conventional manner, assuming a constant thickness D of the second body 26 of 4 mm, against the aforementioned surface with the radii 100/150 mm.
- the radii of the contours 40 and 42 are identical and selected so that they are located between the two radii of the torus. It then turns out that the polishing pressure fluctuations in the outer area amount to at least 96% of the averaged polishing pressure. This causes a strong discontinuous polishing removal and is counterproductive for an even polishing and smoothing effect. A strongly fluctuating polishing process can be expected.
- the radii of the contours 40 and 42 are calculated in such a way that the outer contour 42 presses somewhat flatter than the base radius RB and the radius of the inner contour 40 accordingly compensates for the difference in thickness from the inside to the outside.
- the dynamics of the now calculated polishing pressure then decrease to less than 40% of the averaged polishing pressure pm.
