Definitions

the invention relates to a method and a machine for the CNC-controlled grinding of decorative surfaces, decorative grooves or the like on hollow glasses or the like, according to the preambles of claims 1 and 2.
the object of the invention is to provide a method and a machine with which dimensionally identical decorative patterns can be achieved automatically even with glasses which deviate considerably from their target contour.
the hollow glass 11 to be ground is held in the machine by means of a pivotable workpiece holder 1. 1, the grinding tool 2 moves on a path 3 preprogrammed according to the desired value of the decoration to be ground on the glass into the position 4 shown in broken lines.
a piston-cylinder unit 6 is used the pivotable workpiece holder 1 and thus the workpiece 11 are pressed against the grinding tool 2, the pressure in the piston-cylinder unit 6 being set to a specific value.
This pressure corresponds to a desired machining of the first pre-grinding tool (grinding tool 2), which is designed in such a way that the smallest possible machining deviations occur over the period of use, since this grinding cycle is intended to serve more for sensing the surface and for careful preparation for the following grinding process.
the actual surface is felt in such a way that when there is a contour deviation of the workpiece 11 from the target contour, the counterpressure in the piston-cylinder unit 6 is overcome, and thus there is evasion or pushing against it the grinding wheel 2.
the rest may be identical to the tool 2 used in the pre-grinding, moves into the position 9 during the further processing of the pre-processed decorative surfaces on a path 8 corrected according to the actual contour of the respective glass 11.
