Secans Raterefers to the qty of qualified required size vitream after vitream incisam ante politionem.
Formula vitrei qualificata cum magnitudine quaesita qty x requiritur longitudinis vitreae x requiritur latitudo vitrea / rudis vitrei longitudo / latitudo vitri rudis = secans rate
In principio igitur in norma rudis vitreae magnitudinis schedae rudis intelligentiae clarissima habenda est et quot millimetris (mm.) longitudinis vitreae & latitudinis secandae relinquatur;
| Speculum Crassitudo (mm) | Standar Raw Glass Sheet Size (mm) | L. & W. vitream relinquere debet millimeter (mm). |
| 0.25 | 1000×1200 | 0.1-0.3 |
| 0.4 | 1000×1500 | 0.1-0.3 |
| 0.55/0.7/1.1 | 1244.6×1092.2 | 0.1-0.3 |
| 1.0/1.1 | 1500×1900 | 0.1-0.5 |
| supra 2.0 | 1830×2440 | 0.5-1.0 |
| 3.0 & supra 3.0 | 1830×2400; | 0.5-1.0 |
Exempli gratia:
| Requiritur Vitri Location | 454x131x4mm |
| Standard Raw Glass Sheet Size | 1836x2440mm;2440x3660mm |
| L. & W. vitream relinquere debet millimeter (mm). | 0,5mm pro unaquaque parte |
| Rudis Glass Sheet Size | 1830 | 2440 | 1830 | 2440 |
| Requiritur vitrum magnitudine cum addendi mm cum sectione | 454+0.5+0.5 | 131+0.5+0.5 | 131+0.5+0.5 | 454+0.5+0.5 |
| Qty post crudum schedam divisam per vitream molem requiried | 4.02 | 18.48 | 13.86 | 5.36 |
| Totalis vitreum idoneus qty | 4×18=72pcs | 13×5=65pcs | ||
| Secans Rate | 72x454x131/1830/2440=95% | 65x454x131/1830/2440=80% | ||
| Rudis Glass Sheet Size | 2240 | 3360 | 2240 | 3360 |
| Requiritur vitrum magnitudine cum addendi mm cum sectione | 454+0.5+0.5 | 131+0.5+0.5 | 131+0.5+0.5 | 454+0.5+0.5 |
| Qty post crudum schedam divisam per vitream molem requiried | 4.92 | 25.45 | 16.97 | 7.38 |
| Totalis vitreum idoneus qty | 4×25=100pcs | 16×7=112pcs | ||
| Secans Rate | 100x454x131/2440/3660=66% | 112x454x131/2440/3660=75% | ||
Ita plane cognovimus, 1830x2440mm rudem schedae primae electionis incisurae sunt.
Haven' you got a idea how to count the cutting rate?
