HengereltTekercs10

In metalworking , rolling is a metal forming process in which metal stock is passed through a pair of rolls. Rolling is classified according to the temperature of the metal rolled. If the temperature of the metal is above its recrystallization temperature, then the process is termed as

Casting (metalworking) print that page

Casting

In metalworking , casting involves pouring liquid metal into a mold , which contains a hollow cavity of the desired shape, and then allowing it to cool and solidify. The solidified part is also known as a casting, which is ejected or broken out of the mold to complete the process. Casting

Shearing (metalworking) print that page

Mechanical_Shear_4310

A punch (or moving blade) is used to push the workpiece against the die (or fixed blade), which is fixed. Usually the clearance between the two is 5 to 10% of the thickness of the material, but dependent on the material. Clearance is defined as the separation between the blades, measured at

Bending (metalworking) print that page

Press_Brake

In press brake forming, a work piece is positioned over the die block and the die block presses the sheet to form a shape. [ 1 ] Usually bending has to overcome both tensile stresses as well as compressive stresses . When bending is done, the residual stresses cause the material to spring
