What is percent reduction in relation to drawing?

The Percent reduction after drawing represent the amount of straining or the draw-ability of blank material. The drawing operation relies on the ductility of the blank material. The ductility is affected by the amount of strain a material takes. But there is a limit to which it can be strained. The diameter of the shell to be used is either ID (internal diameter) or OD (outer diameter). But it is convenient to use OD since the cup is normally specified by OD.

How to Calculate Percent reduction after drawing?

Percent reduction after drawing calculator uses Percent reduction after drawing=100*(1-(Outer diameter of shell/Blank Diameter)) to calculate the Percent reduction after drawing, The Percent reduction after drawing represent the amount of straining or the draw-ability of blank material. . Percent reduction after drawing and is denoted by PR symbol.

How to calculate Percent reduction after drawing using this online calculator? To use this online calculator for Percent reduction after drawing, enter Outer diameter of shell (d) and Blank Diameter (BD) and hit the calculate button. Here is how the Percent reduction after drawing calculation can be explained with given input values -> 99 = 100*(1-(0.01/1)).

FAQ

What is Percent reduction after drawing?
