Stamping includes a variety of sheet metal forming manufacturing processes such as punching using a machine press or stamping press blanking embossing bending flanging and coining. The fld is a graph with axes of minor strain on the x axis and major strain on the y axis 7 as shown in fig. Stamped components are made by forming drawing trimming blanking or piercing metalin sheet or coil formbetween two halves upper and lower of a press tool called a die see stamping 101.
We use terminologies.
The best stamped metal part designs take this step by step nature of the stamping process into consideration. If we mark both principle strains in the diagram it is called the strain state of an element. A normal metal stamping process creates a die cut is to drive a sharpened tool steel punch through the sheet or strip material into a die cavity where the slug or scrap is ejected. Originally the forming limit diagram was a 1965 graduate research project with the aim of determining what triggers localized necking and splitting in sheet metal forming and whether the splitting.
