Metal forming and penetration factor
Start on. Some molds will allow for the performance of several operations at once with a single movement. Development of the Predictive General Equation PGE To perform the PGE building process, twelve independent quantities were chosen to express the relation among nine dimensionless groups, as described in Section 2. A very sharp, crisp inside bend radius Ir is generally considered the goal of a coined bend. The springback reduction trend continues to the last fifth iteration. Embed Size px.

Sheet Metal Cutting
Drawing and clamping load were measured for steel and aluminum. Abstract Sheet metal extrusion is a metal forming process in which the movement of a punch penetrates a sheet metal surface and it flows through a die orifice; the extruded parts can be deflected to have an extrusion cavity and protrusion on the opposite side. The results indicated the formation and microstructure effects on the sheet metal extrusion parts and defects. Keywords: drawbead, restraining force, finite element method, sheet metal forming.

Sheet Metal Cutting
Compensation direction for die-face adjustment based on springback compensation. This affects the bend functions, and for profound-radius bends, the parabola effect can be dramatic. DOE was performed to increase the accuracy of the designed model. The accuracy of springback simulation is not only related to springback analysis itself but also strongly dependent on the accuracy of forming processes. Design problem definition 3.
This research investigated the characteristics of the material-flow behavior during the formation and its effect on the microstructure of the extruded sheet metal using the finite element method FEM. The proposal of this paper is to compare the correlation between the main blow parameters: lance height or distance bath lance, flow, kind of tips and penetration and bath movement..
