Abstract
The present invention relates to a cutting method and a cutting device for the superficial scoring of, preferably plate-shaped, components made of glass or ceramics, preferably of glass sheets, and to a method for dividing of, preferably plate-shaped, components made of glass or ceramics, preferably of glass sheets, for example of float glass sheets or laminated glass sheets, in particular laminated safety glass sheets, into individual component cuttings, preferably glass sheet cuttings.
Claims34
A cutting method for the superficial scoring of a plate-shaped component made of glass or ceramic, wherein a scoring process introduces a scoring line by means of a cutting wheel into at least one component surface, wherein the scoring process is monitored by means of acoustic emission analysis,
- wherein in the context of the acoustic emission analysis, a signal analysis and evaluation of digitized acoustic emission time signals detected during the scoring process is carried out, the signal analysis and evaluation being carried out in the time domain and/or in the frequency domain,
- wherein during analyzing and evaluating the detected time signals, at least one actual cutting wheel signal curve is compared with a target cutting wheel signal curve having at least one target characteristic of the at least one actual cutting wheel signal curve, such that peaks or outliers are identified that signify wear of the cutting wheel or a reduction in edge quality of the scoring line.
