Calculate the Length of Developed Blank
Part shown in Figure is to be produced from flat sheet by bending operation. Calculate the length of the developed blank. Assume k = 0.3.
Figure
Solution
Reference to Figure 15.5 the part is a case of straight Bend with the following parameters :
Bend Angle : 90 degree Bend Radius : 5 mm Lengths
L1 : 20 mm
L2 : 15 mm
Bend Allowance = θ (r + kt)
BA = ∏ /2 (5 + 0.3 × 2)
= 8.796 mm
Bend Compensation = - BA
BC = - 8.796 mm
Blank Length = L1 + L2 - BC
= 20 + 15 - (- 8.796)
= 43.796 mm.
