Percent Reduction after Drawing Solution

STEP 0: Pre-Calculation Summary

Formula Used

Percent Reduction after Drawing = 100*(1-Outer Diameter of Shell/Blank or sheet Diameter)
%_r = 100*(1-d_O/d_bk)
This formula uses 3 Variables

Variables Used

Percent Reduction after Drawing - Percent reduction after drawing represents the amount of straining or the draw-ability of blank material.
Outer Diameter of Shell - (Measured in Meter) - Outer Diameter of Shell refer to the measurement across the widest part of any cylindrical object.
Blank or sheet Diameter - (Measured in Meter) - Blank or Sheet Diameter is the diameter of the blank used.

STEP 1: Convert Input(s) to Base Unit

Outer Diameter of Shell: 79.9913 Millimeter --> 0.0799913 Meter (Check conversion here)
Blank or sheet Diameter: 84.25 Millimeter --> 0.08425 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

%_r = 100*(1-d_O/d_bk) --> 100*(1-0.0799913/0.08425)

Evaluating ... ...

%_r = 5.05483679525223

STEP 3: Convert Result to Output's Unit

5.05483679525223 --> No Conversion Required

FINAL ANSWER

5.05483679525223 ≈ 5.054837 <-- Percent Reduction after Drawing

Drawing Force for Cylindrical Shells

Go Drawing Force = pi*Outer Diameter of Shell*Blank Thickness of sheet*Yield Strength*(Blank or sheet Diameter/Outer Diameter of Shell-Cover Friction Constant)

Blank Size for Drawing Operation

Go Blank or sheet Diameter = sqrt(Outer Diameter of Shell^2+4*Outer Diameter of Shell*Height of Shell)

Blank Diameter from Percent Reduction

Go Blank or sheet Diameter = Outer Diameter of Shell*(1-Percent Reduction after Drawing/100)^(-1)

Shell Diameter from Percent Reduction

Go Outer Diameter of Shell = Blank or sheet Diameter*(1-Percent Reduction after Drawing/100)

Percent Reduction after Drawing

Go Percent Reduction after Drawing = 100*(1-Outer Diameter of Shell/Blank or sheet Diameter)

Percent Reduction after Drawing Formula

Percent Reduction after Drawing = 100*(1-Outer Diameter of Shell/Blank or sheet Diameter)
%_r = 100*(1-d_O/d_bk)

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 or sheet 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 is denoted by %_r 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_O) & Blank or sheet Diameter (d_bk) and hit the calculate button. Here is how the Percent Reduction after Drawing calculation can be explained with given input values -> 5.054955 = 100*(1-0.0799913/0.08425).
