Hood design-Week 2

Hemming and Edge Relief

Hemming is a forming operation in which the edges of the sheet are folded or folded over another part in order to achieve a tight fit. Normally hemming operations are used to connect parts together to improve the appearance of a part and to reinforce part edges. The accuracy of the hemming operation is very important since it affects the appearance of the surface and surface quality. Material deformations, which occur during the hemming process, can lead to dimensional variations and other defects in parts. Typical hemming defects are split or wrinkles in the flange, material overlaps in the corner areas or material

Latch Placement

Using the axis of the hinge, a circle is drawn at the middle of the back door and the latch is placed perpendicular to that circle.

Embossing

To reduce the weight of Hood, some materials are removed and embosses are created to give stiffness to the panel. Sheet metal embossing is a stamping process for producing raised or sunken designs or relief in sheet metal. In this project the Embosses are created to divide the force towards the hinge joints during collision.
