Blank Size for Drawing Operation Solution

STEP 0: Pre-Calculation Summary

Formula Used

Sheet Diameter = sqrt(Outer Diameter of Shell^2+4*Outer Diameter of Shell*Shell Height)
D_b = sqrt(d_s^2+4*d_s*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

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.
Shell Height - (Measured in Meter) - Shell Height is the longitudinal length measured along its axis.

STEP 1: Convert Input(s) to Base Unit

Outer Diameter of Shell: 80 Millimeter --> 0.08 Meter (Check conversion here)
Shell Height: 2.15 Millimeter --> 0.00215 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

D_b = sqrt(d_s^2+4*d_s*h_shl) --> sqrt(0.08^2+4*0.08*0.00215)

Evaluating ... ...

D_b = 0.0841902607193968

STEP 3: Convert Result to Output's Unit

0.0841902607193968 Meter -->84.1902607193967 Millimeter (Check conversion here)

FINAL ANSWER

84.1902607193967 ≈ 84.19026 Millimeter <-- Sheet Diameter

Drawing Force for Cylindrical Shells

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

Blank Size for Drawing Operation

Go Sheet Diameter = sqrt(Outer Diameter of Shell^2+4*Outer Diameter of Shell*Shell Height)

Blank Diameter from Percent Reduction

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

Shell Diameter from Percent Reduction

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

Percent Reduction after Drawing

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

Blank Size for Drawing Operation Formula

Sheet Diameter = sqrt(Outer Diameter of Shell^2+4*Outer Diameter of Shell*Shell Height)
D_b = sqrt(d_s^2+4*d_s*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.

How to Calculate Blank Size for Drawing Operation?

Blank Size for Drawing Operation calculator uses Sheet Diameter = sqrt(Outer Diameter of Shell^2+4*Outer Diameter of Shell*Shell Height) to calculate the Sheet Diameter, Blank Size for Drawing Operation is defined as the initial dimensions of the material, typically a flat sheet, before it's formed into a specific shape through drawing. This measurement determines the starting point for material transformation and is essential for achieving the desired final product dimensions. Sheet Diameter is denoted by D_b symbol.

How to calculate Blank Size for Drawing Operation using this online calculator? To use this online calculator for Blank Size for Drawing Operation, enter Outer Diameter of Shell (d_s) & Shell Height (h_shl) and hit the calculate button. Here is how the Blank Size for Drawing Operation calculation can be explained with given input values -> 84190.26 = sqrt(0.08^2+4*0.08*0.00215).
