Difference Between Bulk Forming And Sheet Metal Forming

Bulk and sheet forming flashcards.

Difference between bulk forming and sheet metal forming.

Describe the similarities and the differences between the bulk deformation processes and the sheet metal forming processes we have studied. Describe a the similarities and b the differences between the bulk deformation processes considered last week and the sheet metal forming processes looked at in this week s lecture. Bulk forming processes one is bulk forming and the other is sheet metal forming. The main characteristic of these processes is that the final product has the dimensions of a magnitude similar to the sheet thickness projecting out of the plane of the sheet.

The key difference between bulk deformation and sheet metal forming is that in bulk deformation the work parts have a low area to volume ratio whereas in sheet metal forming the area to volume ratio is high. Rolling forging extrusion and drawing are bulk forming processes. Bulk deformation refers to the use of raw materials for forming which have a low surface area to volume ratio. Bulk causes workpiece to deform plastically pushed to fill die sheet metal is on workpiece of sheets or strips pushed into a die 17 2 extrusion is a fundamental shaping process.

The most typical in this group is the embedded pin transducer technique. In bulk deformation processes the workpiece undergoes large plastic deformation.

Recent developments in metal forming technology lead to the development of a new group of metal forming processes entitled sheet bulk metal forming. Deformation processes are important in transforming one shape of a solid material into another shape. In sheet metal processes the area to volume ratio is high. They each use a different method.

Differences in plastic flow resulting from the plane stress conditions of sheet metal forming and the three dimensional stress conditions of bulk metal forming have long been utilized to classify metal forming processes into two different groups. In summary they may be divided into the following categories. Create flashcards for free and quiz yourself with an interactive flipper. Forging and forming aren t the same however.

Bulk deformation shape changes are significant work parts have a low surface area to volume ratio. From iron and steel to aluminum bronze and more countless metals and alloys support these two metalworking processes.
