Resumo

INSPECTION OF THE SIDE-TRIMMING PROCESS IS IN THE MEANTIME STATE OF THE ART. BASED ON OPTICAL MEASUREMENT TECHNOLOGY IMAGES FROM THE STRIP EDGE SURFACE ARE TAKEN, VISUALIZED AND EVALUATED BY ALGORITHM. THIS DISPLAYED INFORMATION ALLOWS OPERATORS DECIDING ON SHORT-TERM ACTIONS LIKE KNIFE CHANGE OR SIDE-TRIMMER PARAMETER ADJUSTMENT AS WELL AS STAFF FROM QUALITY DEPARTMENT STARTING IMPROVEMENTS FOR THE SIDE TRIMMING PROCESS BASED ON THAT INFORMATION. EXPERIENCE FROM EXISTING INSTALLATIONS SHOW THAT DUE TO LIMITED RESOURCES AVAILABLE FOR THIS SIDE-PROCESS BY INVOLVED PERSONNEL THIS PROCESS WAS NOT TAPPED TO THE FULL POTENTIAL. THE PAPER WILL DESCRIBE AN IMPROVED APPROACH FOR EASIER AND CLEARER DECISION PROCESS FOR OPERATION. FIRST HIGHLIGHT OF THE UPDATE IS THE POSSIBILITY TO ADDITIONALLY MEASURE THE STRIP WIDTH. SECOND HIGHLIGHT IS THE POSSIBILITY TO ADJUST THE ORIENTATION OF THE SENSOR DEPENDING ON THE ORIENTATION OF THE STRIP. BASIS FOR THESE EXAMINATIONS WAS THE INSTALLED BASE OF EDGEMON ALL OVER THE WORLD. THE COLLECTION OF MEASUREMENT DATA ALLOWED STATISTICAL CORRELATION BETWEEN DEFECT AND PROCESS EFFECT WHICH ADDITIONALLY LED TO AN IMPROVEMENT OF RELIABILITY. BASED ON THAT INFORMATION MEASURES CAN BE EASILY DERIVED FOR THE MOST CRUCIAL PARAMETERS INFLUENCING THE PROCESS.
