5. Referencia técnica
1.ª pasada, penetración
= 0.23 mm
= .009 pulg.
2.ª pasada, penetración
0.42 - 0.23 = 0.19 mm
.017 - .009 = .008 pulg.
3.ª pasada, penetración
0.59 - 0.42 = 0.17 mm
.023 - .017 = .006 pulg.
4.ª pasada, penetración
0.73 - 0.59 = 0.14 mm
.029 - .023 = .006 pulg.
5.ª pasada, penetración
0.84 - 0.73 = 0.11 mm
.033 - .029 = .004 pulg.
6.ª pasada, penetración
0.94 - 0.84 = 0.10 mm
.037 - .033 = .004 pulg.
