Blank Diameter from Percent Reduction Solution

STEP 0: Pre-Calculation Summary
Formula Used
Sheet Diameter = Outer Diameter of Shell*(1-Percent Reduction after Drawing/100)^(-1)
Db = ds*(1-PR%/100)^(-1)
This formula uses 3 Variables
Variables Used
Sheet Diameter - (Measured in Meter) - Sheet Diameter is the diameter of a circular sheet or disc-shaped object. In sheet metalworking, the diameter of a sheet metal blank before any forming or shaping operations are performed on it.
Outer Diameter of Shell - (Measured in Meter) - Outer Diameter of Shell is the measurement across the widest part of any cylindrical object.
Percent Reduction after Drawing - Percent Reduction after Drawing is a measure used in metalworking processes, particularly in drawing operations, to quantify the amount of deformation.
STEP 1: Convert Input(s) to Base Unit
Outer Diameter of Shell: 80 Millimeter --> 0.08 Meter (Check conversion ​here)
Percent Reduction after Drawing: 5 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Db = ds*(1-PR%/100)^(-1) --> 0.08*(1-5/100)^(-1)
Evaluating ... ...
Db = 0.0842105263157895
STEP 3: Convert Result to Output's Unit
0.0842105263157895 Meter -->84.2105263157895 Millimeter (Check conversion ​here)
FINAL ANSWER
84.2105263157895 84.21053 Millimeter <-- Sheet Diameter
(Calculation completed in 00.020 seconds)

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 Blank Diameter from Percent Reduction?

Blank Diameter from Percent Reduction calculator uses Sheet Diameter = Outer Diameter of Shell*(1-Percent Reduction after Drawing/100)^(-1) to calculate the Sheet Diameter, The Blank Diameter from Percent Reduction is obtained by using percent reduction obtained after drawing process to work back towards blank diameter. Sheet Diameter is denoted by Db symbol.

How to calculate Blank Diameter from Percent Reduction using this online calculator? To use this online calculator for Blank Diameter from Percent Reduction, enter Outer Diameter of Shell (ds) & Percent Reduction after Drawing (PR%) and hit the calculate button. Here is how the Blank Diameter from Percent Reduction calculation can be explained with given input values -> 84210.53 = 0.08*(1-5/100)^(-1).
