Drawing Force Formula
The following equation is used to calculate the Drawing Force.
FD = C*T*S
- Where FD is the drawing force (lbf)
- C is the mean circumference of the shell (in)
- T is the stock thickness (in)
- S is the tensile strength (lbf/in^2)
To calculate the drawing force, multiply the circumference by the stock thickness, then multiply by the tensile strength.
What is a Drawing Force?
Drawing force is the force required to draw a wire or a rod through a forming die.
Drawing is a metalworking process that uses tensile forces to stretch metal or glass.
How to Calculate Drawing Force?
The following example outlines the steps and information needed to calculate the Drawing Force.
First, determine the mean circumference of the shell. In this example, the mean circumference is measured to be 5 inches.
Next, determine the thickness of the material. This material is 1.5 inches thick.
Next, determine the tensile strength of the material. For this problem, the tensile strength is found to be 5,000 lbf/in^2.
Finally, calculate the drawing force using the formula above:
FD = C*T*S
FD =5 * 1.5 * 5000
FD = 37,500 lbf
