Difference between bulk forming and sheet metal forming. A more comprehensive list applicable to other metal forming processes including bulk and sheet metal forming has been presented by schey 1983. Describe the similarities and the differences between the bulk deformation processes and the sheet metal forming processes we have studied. 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 summary they may be divided into the following categories. Forging and forming aren t the same however. 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.

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. In sheet metal processes the area to volume ratio is high.

Rolling forging extrusion and drawing are bulk forming processes. Bulk deformation shape changes are significant work parts 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. Forging and forming are two common types of metalworking processes.

Bulk deformation refers to the use of raw materials for forming which have a low surface area to volume ratio. They each use a different method. Bulk and sheet forming flashcards. From iron and steel to aluminum bronze and more countless metals and alloys support these two metalworking processes.

The most typical in this group is the embedded pin transducer technique. Bulk forming processes one is bulk forming and the other is sheet metal forming.
