Difference Between Bulk Forming And Sheet Metal Forming

They both involve the manipulation of metal to achieve a different size and or shape.

Difference between bulk forming and sheet metal forming.

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. Recent developments in metal forming technology lead to the development of a new group of metal forming processes entitled sheet bulk metal forming. Rolling forging extrusion and drawing are bulk forming processes. Forging and forming are two common types of metalworking processes.

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

Bulk and sheet forming flashcards. 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. In summary they may be divided into the following categories. Get more help from chegg get 1 1 help now from expert mechanical engineering tutors.

A more comprehensive list applicable to other metal forming processes including bulk and sheet metal forming has been presented by schey 1983. In sheet metal processes the area to volume ratio is high. Bulk forming processes one is bulk forming and the other is sheet metal forming. Deformation processes are important in transforming one shape of a solid material into another shape.

They each use a different method. Bulk deformation refers to the use of raw materials for forming which have a low surface area to volume ratio. In bulk deformation processes the workpiece undergoes large plastic deformation. Forging and forming aren t the same however.
