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)
Db = sqrt(ds^2+4*ds*hshl)
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
Db = sqrt(ds^2+4*ds*hshl) --> sqrt(0.08^2+4*0.08*0.00215)
Evaluating ... ...
Db = 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

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 Db 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 (ds) & Shell Height (hshl) 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).

FAQ

What is Blank Size for Drawing Operation?
