1ère passe, pénétration
= 0.23 mm
= .009 pouce
2ème passe, pénétration
0.42 – 0.23 = 0.19 mm
.017 – .009 = .008 pouce
3ème passe, pénétration
0.59 – 0.42 = 0,17 mm
.023 – .017 = .006 pouce
4ème passe, pénétration
0.73 – 0.59 = 0.14 mm
.029 – .023 = .006 pouce
5ème passe, pénétration
0.84 – 0.73 = 0.11 mm
.033 – .029 = .004 pouce
6ème passe, pénétration
