SHEARING • It is a process of cutting a straight line across a strip, sheet • Metal is placed between upper punch & lower die. • Pressure is applied, plastic deformation takes place. • As the pressure is continued, the .
8. Advantages of Cold Working: o Better surface finish is being obtained. o This process provides higher dimensional accuracy o Widely applied as a forming process for steel. o Thin material can be obtained. o More suitable for mass production. Disadvantages of Cold Working: o Close tolerances cannot be achieved. o Brittle materials cannot be cold worked. o .
16. METAL SPINNING. Metal spinning, also called conventional spinning or just spinning, is the forming of an axis-symmetric part over a rotating mandrel Force is delivered by a tool with a rounded end or a roller A flat, or possibly preformed, work piece is held between a mandrel and tail stock As the apparatus rotates, the tool applies localized pressure to the work .
In this process, Metal is heated above the RT with 0.7 to 0.9 times of the melting temperature. . also known as spin forming or spinning or metal turning most commonly, is a metalworking process by which a disc or tube of metal is rotated at high speed and formed into an axially symmetric part.

92. Con.. Conventional Spinning: A sheet metal disk is held against the end of a rotating Mandrel of the desired inside shape of the final part, while the tool or roller deforms the metal against the mandrel. In some cases, the starting workpart is other than a flat Disk. The process requires a series of steps, as indicated in the fig, to complete the shaping Of the part.

Metal spinning is a chipless forming process used to produce axisymmetric parts like cups, cylinders and cones. It works by rotating a metal blank over a mandrel while a spinning tool presses and forms the blank according to the mandrel's profile.Sheet-Metal Parts (a) (b) Figure Examples of sheet-metal parts.

Figure (a) Schematic illustration of the shear-spinning process for making conical parts. The mandrel can be shaped so that curvilinear parts can be spun. Difference: In the punching process the final product is the metal sheet from which metal is removed. In blanking process the final product is the removed portion from the sheet. 6. Punching Press: It is a type of machine press used to cut the material. Can be very simple and manually controlled or very complex and CNC controlled.
3. Sheet metal, which acts as the workpiece in these processes, is one of the most common forms of raw material stock. The material thickness that classifies a workpiece as sheet metal is not clearly defined. However, sheet .In bending and embossing of sheet metal, the female die is replaced with rubber pad Rubber pad forming (RPF) is a metalworking process where sheet metal is pressed between a die and a rubber block, made of polyurethane. Under pressure, the rubber and sheet metal are driven into the die and conform to its shape, forming the part.
