Blank Size for Drawing Operation Solution

STEP 0: Pre-Calculation Summary

Formula Used

Blank or sheet Diameter = sqrt(Outer Diameter of Shell^2+4*Outer Diameter of Shell*Height of Shell)
d_bk = sqrt(d_O^2+4*d_O*H_shl)
This formula uses 1 Functions, 3 Variables

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Blank or sheet Diameter - (Measured in Meter) - Blank or Sheet Diameter is the diameter of the blank used.
Outer Diameter of Shell - (Measured in Meter) - Outer Diameter of Shell refer to the measurement across the widest part of any cylindrical object.
Height of Shell - (Measured in Meter) - Height of Shell is the longitudinal length measured along its axis.

STEP 1: Convert Input(s) to Base Unit

Outer Diameter of Shell: 79.9913 Millimeter --> 0.0799913 Meter (Check conversion here)
Height of Shell: 2.15 Millimeter --> 0.00215 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

d_bk = sqrt(d_O^2+4*d_O*H_shl) --> sqrt(0.0799913^2+4*0.0799913*0.00215)

Evaluating ... ...

d_bk = 0.0841815493780555

STEP 3: Convert Result to Output's Unit

0.0841815493780555 Meter -->84.1815493780555 Millimeter (Check conversion here)

FINAL ANSWER

84.1815493780555 ≈ 84.18155 Millimeter <-- Blank or sheet Diameter

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)

Blank Size for Drawing Operation Formula

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

How to determine Blank Size for Drawing Operation for cylindrical shells?

This calculator gives the blank diameter for cylindrical shells for relatively thin materials. The calculation could be based on volume, surface area or by layout. These are only the theoretical blank sizes, based on the surface area of the shell and blank. For practical purposes, it is necessary to add additional allowances to provide for trimming of the uneven and irregular rim of the deep drawn cup. This is termed as trim allowance. The trim allowance could be 3 mm for the first 25 mm cup diameter and additional 3 mm for each of the additional 25 mm of cup diameters.
