Definitions
- the invention relates to a method for grinding and / or polishing a defect in the surface coating of a workpiece according to the preamble of claim 1 and a device for carrying out the proceedings procedural.
- the contact pressure and the grinding or polishing movement are decisive for the machining result.
- the contact pressure results in the processing of a horizontal surface of the mass of the grinding tool and the additional Lich manually applied force to the surface.
- the invention has for its object to further develop a method of the generic type so that the grinding or polishing result is optimized, with simultaneous reproducibility.
- the mass of the grinding tool is compensated insofar as it has no influence on the result.
- the grinding movement of the grinding tool and its movement type, i. the orbital, rotary and / or vibratory movements are coordinated and stored in a computer to be executed grinding and polishing track in a computer.
- the grinding or polishing disc is first performed along a con centric to the faulty inner slideway and then ent uninterrupted ent long led a spiral-shaped slideway in an outer concentric slideway.
- the grinding or polishing wheel is tilted during the circular grinding movement with respect to the perpendicular to the defect by a predetermined angle inwards and defines a cone angle.
- This Ke gelwinkel amplifies the grinding performance in the center of the circular path, so that the defect is targeted, easier and faster processed and creates a smooth transition to the edge of the grinding point.
- the radius of the outer concentric grinding path is not greater than half the diameter of the grinding plate or the grinding or polishing wheel.
- An apparatus of the method according to the invention is designed such that a grinding or polishing tool is formed as robot connected to a computer Ro, which has a fixed to an arm, orbital, rotating and / or vibrating movable support plate for holding a grinding or polishing pad, wherein the arm is computer-controlled movable.
- Fig. 3 to 5 the movement of the polishing according to the invention, also in a schematic view, respectively.
- the grinding movement and the movement type of a grinding tool are stored as an automatic grinding path in the computer as a work program.
- the center point of the grinding wheel or of the support plate is aligned with the defect 1 to be ground, with the grinding path starting in an inner circle 2.
- the center of the grinding wheel is tilted inwardly with respect to the perpendicular to the defect 1 by a predetermined angle, under at setting a cone angle.
- the grinding tool and the workpiece to be machined are usually oriented orthogonal to each other.
- the grinding wheel can be guided one or more times along the grinding path 2.
- the grinding wheel is guided in a concentric grinding track 4 and although without employment of the grinding wheel in a cone angle, whereby the grinding transitions smoothed and a flat Endresul is achieved.
- the sanding track 4 can also be sanded one or more times.
- the distance between the defect 1, the grinding path 2 and the grinding path 4 is dependent on the size of the defect 1 and its expression as well as the diameter D of the grinding wheel.
- the spiral track 3 can be different lengths depending on the extent of the defect.
- the radii of the grinding tracks 2 and 4 must always be smaller than half the diameter D of the grinding disc or grinding wheel, whereby in particular special by the inner circular path 2, the faulty point of the workpiece to be machined undergoes a more intensive continuous processing and thereby the in Figure 2 represented so-called effective grinding surface F1 is ent.
- the distance between the radii R1, R2 of the sliding tracks 2 and 4 can be adjusted accordingly depending on the defect to be processed.
- the distance between the inner grinding path 2 and the outer grinding path 4 is chosen to be as small as possible to effectively handle defects in areas such as along edges of a body of a motor vehicle ent long the fat edges of the body modules and in tight radii of the body ,
- the sliding tracks 2 and 4 are assigned grinding times, as well as to pressure forces of the grinding tool and speeds or stroke rates. In doing so, they always have the same shape and form in a shorter time than previously produced grinding points, so they are reproducible.
- the cone angle is continuously reduced to 0 to start the grinding path 3 in a previously defined route.
- Another advantage of the method according to the invention is that the shape of the abrasive can be made smaller on a support, whereby the abrasive requirement is significantly reduced, as well as the not agile energy needs.
- a computer-aided statistical evaluation between a number of errors and the consumption of abrasives serves as the basis for a continuous improvement process.
- FIGs 3-5 the sequence of movement of a Polierwerkzeu ges is shown schematically in an automated polishing.
- the polishing movement and the movement of the polishing tool are also computer controlled, the corresponding parameters are stored in a computer.
- the center of the polishing head is exactly aligned with the defect 1.
- polishing contours for example, the surface of affyka rosette, the polishing tool and the surface are orthogonal to each other out.
- a first polishing sheet 5 is shown, which starts at the defect 1 be and extends spirally outward.
- the contact pressure is regulated in stages, where the adjustment takes place as a function of the track length.
- the control of the contact pressure for example, is supported by corresponding pressure sensors in the robot.
- the movement commences according to the Po lierbahn 5 with a contact pressure P1, which is reduced along the polishing path 5 to the outside Shen.
- the contact pressure is reduced wei ter to smooth the polishing transition.
- the contact pressure is reduced in order to prevent heating of the usually formed as a polishing sponge polishing pad.
- the polishing times along the polishing tracks 5, 6 as well as the pressing pressures and the respective rotational or stroke numbers of the polishing tool are stored in a corresponding program of the computer.
- the Po lierzeit is adapted to the size of the grinding point.
- the polishing points are to produce by the inventive method in a much shorter rer time and, moreover, always the same expression and Shape, so are reproducible. As a result, the polish can be noticeably reduced, as well as the energy requirements.
