the aim of this paper is to develop a systematic method to analyze the effects of forming parameters on the quality of part formability and determine the optimal combination of the forming parameters for the sheet hydroforming process. in this paper, the effects of four important process parameters namely fluid pressure, friction coefficient at blank/punch interface, gap between die rim block a...

Sheet metal forming is one of the major processes in manufacturing and is broadly used due to its high degree of design flexibility and low cost. In the sheet metal forming process, draw-in (planar movement of a sheet periphery) frequently occurs and is one of the most dominated indicators on the success of a forming process. Currently, monitoring and controlling draw-in during each stamping op...

The cup drawing is a basic deep drawing process. Thus, understanding the mechanics ofthe cup drawing process helps in determining the general parameters that affect the deep drawingprocess. There are mainly two methods of analysis; experimental and analytical/numerical.Experimental analysis can be useful in analyzing the process to determine the process parameters thatproduce a defect free prod...

Thin glass sheets may be manufactured using a two-part process in which a sheet is first cast and then subsequently reheated and drawn to a required thickness. The latter redrawing process typically results in a sheet with non-uniform thickness and with smaller width than the cast glass block. Experiments suggest that the loss of width can be minimized and the non-uniformities can be essentiall...

Abstract Composite components combine the benefits of different materials, leading to improved product properties, enhanced resource- and energy efficiency widening spectrum. Draw-forging is unique combination deep-drawing cold forging, where a core material encapsulated within thin sheet metal blank. Previously, basic draw-forging process only allowed covering shaft tip, covered length was lim...

A recent development in sheet metal forming industry is the application of tailored blanks: blanks prepared from separate pieces of sheet material, welded together prior to the forming process. The pieces of sheet material can have different properties, enabling weight reduction of components, corrosion resistance using cathodic protection or the possibility to create local weak spots, resultin...

Easydrawer is a graphical computer application which helps users to draw 2D constructions as they would do on a sheet of paper using a pair of compasses, a ruler and a pen. Easydrawer can significantly increase the productivity of geometrical drawers and help in making the construction process transparent to persons who are currently trained in technical drawing. The application comes with some...
