This separation is caused by shearing forces acting on the metal through the edges of the punch and die.
Trimming operation sheet metal.
In this article we will discuss various sheet metal cutting operations and their application.
In this operation a sheet metal workpiece is placed or kept between two dies from one end.
Trimming is a manufacturing process that is used as a finishing operation for forged parts in order to remove flash.
Flash is a characteristic common in most metal forgings.
Sheet metal cutting operations involve the removal of the material from larger sheets.
Simply put cutting operations cause the sheet metal to be stressed beyond its ultimate strength therefore breaking its structure and separating into different parts.
It leaves a lean edge on the piece of metal is sheared or cut.
Pressworking a term referencing sheet metal operations in general.
Sheet metal cutting occurs due to shearing forces acting on the metal through the edges of the punch and die.
For that reason trimming while not technically a forging or even a forming operation in general is discussed in this section.
And the punch is hit at the other end of the sheet producing a shearing effect.
Cutting operations involve the separation of the metal of the sheet in certain areas.
