STYLUS GAP MEASURING APPARATUS FOR GRAVURE ENGRAVING MACHINE

摘要

PROBLEM TO BE SOLVED: To easily and accurately measure a gap amount of styluses by obtaining a width of cells and a width of channels formed between adjacent two cells from image information, and calculating the gap amount from these data. ;SOLUTION: In the case of measuring a gap amount, density data (d) so that a shift amount of a stylus becomes equivalent to a displacement amount by the density data is obtained (S10). A test-engraving is executed by using the data (d) in a manual mode (S10). A size of a cell formed by the test- engraving is actually measured (S12). A virtual channel width W2 is calculated based on a cell width W1 and cell length 1 (S13). A gap amount S is obtained from the width W1 obtained by the actual measurement and the width W2 (S14). A gap amount S obtained by converting into the cell width is converted into an actual gap amount (S) by using a value of an angel of a cutting edge of the stylus (S15).;COPYRIGHT: (C)1999,JPO
