Blank Size when there is Corner Radius on Punch Solution

STEP 0: Pre-Calculation Summary
Formula Used
Blank Diameter = sqrt(Outer Diameter of Shell^2+4*Outer Diameter of Shell*Shell Height-0.5*Corner Radius on Punch)
dbl = sqrt(ds^2+4*ds*hshl-0.5*rcn)
This formula uses 1 Functions, 4 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 Diameter - (Measured in Meter) - Blank Diameter refers to the initial diameter of the material before any forming or shaping process is applied.
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.
Corner Radius on Punch - (Measured in Meter) - Corner Radius on Punch is that radius or rounded edge or curvature present on the punch used in a manufacturing process.
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)
Corner Radius on Punch: 0.003001 Millimeter --> 3.001E-06 Meter (Check conversion ​here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
dbl = sqrt(ds^2+4*ds*hshl-0.5*rcn) --> sqrt(0.08^2+4*0.08*0.00215-0.5*3.001E-06)
Evaluating ... ...
dbl = 0.0841813488844174
STEP 3: Convert Result to Output's Unit
0.0841813488844174 Meter -->84.1813488844174 Millimeter (Check conversion ​here)
FINAL ANSWER
84.1813488844174 84.18135 Millimeter <-- Blank Diameter
(Calculation completed in 00.004 seconds)

How to determine blank size for drawing?

One of the first jobs of the draw die designer is to find the size of the blank to be used for making a given cup. It is often difficult to find a blank of the exact size required for making a given shell because of thinning and thickening of sheet during drawing. 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.
