2. Conversionis formula generalis filum Britanniae Ictibus;
1 inch = 25.4mm (code)
Exemplum 1: (1/4-30)
1/4×25.4＝6.35 (diametri dens)
25.4÷30＝0.846 (dens procul)
Deinde 1/4-30 in dentes metricos conversi debet esse: M6.35×0.846
Exemplum 2: (3/16-32)
3/16×25.4＝4.76 (diam dentem)
25.4÷32＝0.79 (dens procul)
Deinde 3/16-32 in dentes metricos conversi debet esse: M4.76×0.79
3. Formula generalis dentium in metricos convertendi dentes Britannicos;
Numerator denominator 25.4 = dente diametro exteriore (idem ut supra)
Exemplum 1: (3/8-24)
3÷8×25.4＝9.525 (diam exteriorem dens)
25.4÷24＝1.058 (pix metrica)
Deinde 3/8-24 in dentes metricos conversi esse debent: M9.525×1.058
4. Formula convertendi Americanos dentes ad dentes metricos;
Exemplum: 6-32
6-32 (0.06+0.013)/code×6＝0.138
0.138×25.4＝3.505 (diametri exterioris dente)
25.4÷32＝0.635 (dens procul)
Deinde 6-32 in dentes metricos conversi debet esse: M3.505×0.635
1. Calculi formula foraminis diametri interioris;
Diameter exterior dentis - 1/2 debet esse picis dens;
M3.505－1/2×0.635＝3.19
Tunc dyameter interior 6-32 debet esse 3.19
2. Extrusio filum Ictibus algorithmus interioris foraminis:
Forma calculi simplex diametri inferioris foraminis 1;
Dens diametri exterioris - (dens picis 0,4250.475)/ code = inferiore foramen diametri
Exemplum 1: M6×1.0
M6- (1.0×0.425)= 5.575 (apertura maxima inferior)
M6-(1.0×0.475)=5.525(minimum)
Exemplum 2: Simplex ratio calculi pro diametro interiore foraminis a filo inciso pulsato;
M6－ (1.0×0.85)=5.15 (maximum)
M6－ (1.0×0.95)＝5.05(minimum)
M6－
Exemplum 3: M6×1.0＝6-1.0＝5.0+0.05＝5.05
5. Simplex formula computandi diametrum exteriorem dentium torcularium;
1. Diameter - 0.01 × 0,645 picem (egere transire et consistere)
Exemplum I: M3×0.5＝3-0.01×0.645×0.5＝2.58 (diametri exterioris)
Exemplum 2: M6×1.0＝6-0.1×0.645×1.0＝5.25 (diametri exterioris)
6. Calculation formula metrica dentis volventis diametri: (calculi densi plenus)
Exemplum I: M3×0.5＝3-0.6495×0.5＝2.68 (diametri exterioris ante conversionem)
Exemplum 2: M6×1.0＝6-0.6495×1.0＝5.35 (diametri exterioris ante conversionem)
7. Impressum diametro exterioris profunditatis (diametri exterioris)
Diameter exterior (25.4).
Exempli gratia: 4.1÷25.4×0.8 (picis floris) = 0.13 Altitudo scalptura 0.13 debet esse.
8. Formulae conversionis diametri pro materiis polygonalibus;
1. Quadratus: diameter 1.414 = diametrum diagonalem
2. Pentagonum: diameter diametri 1.2361 = diameter diametri
3. Hexagon: Diameter laterum oppositorum × 1.1547 = Diameter angulorum oppositorum
Formula 2: 1. Quattuor angulis: diameter diametri 0.71 = diametri diagonalis
