Sheet Metal Trimming Operation

Following are the 9 different types of sheet metal operations.

Sheet metal trimming operation.

Sheet metal cuttingis a major classification for many different pressworking operations. In this article we will discuss various sheet metal cutting operations and their application. Cutting operations involve the separation of the metal of the sheet in certain areas. Cutting and forming thin sheets of metal usually performed as cold working sheet metal 0 4 1 64 to 6 mm 1 4in thick plate stock 6 mm thick advantage high strength good dimensional accuracy good surface finish economical mass production low cost.

Pressworking a term referencing sheet metal operations in general. Flash is a characteristic common in most metal forgings. Press working operations or sheet metal operations. Variety of sheetmetal cutting operations are possible.

These products have good strength with light weighted characteristic versatility in shapes low cost fast production rate and many more advantages which make is suitable for every manufacturing industries. Module 5 sheet metal operations. Shaving trimming is a finishing operation in which shearing off of burrs from the cut edges is carried out in order to make the edges smooth and also impart dimensional accuracy. Sheet metal operation gives many advantages over forging or casting process which makes it a most versatile operation.

When a great enough shearing force is applied the shear stress in the material will exceed the ultimate shear strength and the material will fail and separate at the cut location. Sheet metal cutting operations involve the removal of the material from larger sheets. Cutting and forming thin sheets of metal usually performed as cold working sheet metal 0 4 1 64 to 6 mm 1 4in thick plate stock 6 mm thick advantage high strength good dimensional accuracy good surface finish economical mass production low cost. By physical removal of the material from the sheet if the required shape of the component is obtained called as cutting or shearing operation.

Sheet metal cutting occurs due to shearing forces acting on the metal through the edges of the punch and die. It is a cut in a straight line across a strip sheet or bar. Trimming is a manufacturing process that is used as a finishing operation for forged parts in order to remove flash. For that reason trimming while not technically a forging or even a forming operation in general is discussed in this section.
