1. SHEET METAL FABRICATION• Sheet metal typically begins as sheets, but after undergoing cutting, bending, stamping and welding operations it takes on useful engineering forms. • Sheet metal has become a significant material for, - automotive bodies and frames, • Sheets are popular materials because the sheets themselves are easy to produce, and the subsequent operations can be performed easily. The major operations typically include, bending - an angle is used to create non-parallel faces punching/shearing/blanking - a major portion of the material is cut off by putting the material in shear. 1.1 SHEET METAL PROPERTIES1.2 SHEARING1.3 DEEP DRAWING1.4 SPINNING1.5 MAGNETIC PULSE FORMING1.6 HYDROFORMING1.7 SUPERPLASTIC FORMING1.8 PRACTICE PROBLEMS |
