DEFECTS METAL WORKING AND ROLLED PRODUCTS. What is a stamping operation? A sheet formed part is usually obtained through a number of operation (phases) final surface intermediate surface Each operation can be decomposed in several phases. It may be necessary to model each of them • Gravity fall • Holding • Forming • Trimming, flanging • Springback Most problems in sheet metal forming come from a bad control of holding, The raw material for sheet metal manufacturing processes is the output of the rolling process. Typically, sheets of metal are sold as flat, rectangular sheets of standard size. Therefore the first step in any sheet metal process is to cut the correct shape and sized ‘blank’from larger sheet. 2 3 Sheet Metal Cutting & Forming Processes-General-Sheet metal processing is an important process.

Press types Open back One of the principal concerns in a sheet metal operation, is the spring back of the metal. When the metal is deformed, it is first elastically deformed and then plastically. When the applied load is removed, the plastic component of the deformation remains permanently, but the elastic part springs back to its original shape. February 6, 2012 P N Rao 21 February 6 There are various types of blanking and piercing: lancing, perforating, notching, nibbling, shaving, cutoff, and dinking. Lancing. Lancing is a piercing operation in which the workpiece is sheared and bent with one strike of the die.
