Question 3:

Calculating Sheet Metal Weight A sheet metal part has dimensions of 500 mm x 300 mm and a thickness of 3 mm. Calculate the weight of this sheet metal part, assuming the material used has a density of 7.85 g/cm³.

Solution: The weight of the sheet metal part can be calculated using the formula: Weight = Volume *

Density

Given: Length (L) = 500 mm Width (W) = 300 mm Thickness (t) = 3 mm Density of material (D) = 7.85 g/cm³

First, convert the dimensions to centimeters: L = 500 mm = 50 cm W = 300 mm = 30 cm t = 3 mm = 0.3 cm

Calculate the volume: Volume = L * W * t

Substituting the known values: Volume = 50 cm * 30 cm * 0.3 cm

Finally, calculate the weight: Weight = Volume * Density

Substituting the known values: Weight = (50 cm * 30 cm * 0.3 cm) * 7.85 g/cm³

Therefore, the weight of this sheet metal part is 3525 g (approximately).

Question 4:

What is the K-Factor in sheet metal bending?

Solution: The K-Factor is a constant used in sheet metal bending calculations to determine the neutral axis position during the bending process. It relates the distance from the neutral axis to the inner surface of the bend with the material's thickness and mechanical properties. The K-Factor varies depending on the material type, thickness, and bending method. It is typically provided by material suppliers or can be determined experimentally. In SolidWorks, the K-Factor is used to calculate the bend allowance and develop accurate flat patterns.
