Weight and Scrap Percentage

Figure 2:2. Figure describing material and the scrap areas.

1. The area of the "frame" containing manufacturing excess. The width is 15 mm.

2. The area of the excess defined in the generation of the panel. For a plane plate, it is approximated by a straight "strip" between the starting point and the ending point of the excess interval. It is not taken into consideration that parts of this strip may fall within, for example, cutouts for profiles.

3. The area of the detail as it is supposed to be when put into its final position in the ship (however, cf. B).

4. The area of the least circumscribed rectangle, falling outside the detail.

The weight of the detail is computed from the area C.

The scrap percentage is calculated as .
