The formula to calculate the Draw Reduction is:
\[ DR = \frac{I - F}{I} \times 100 \]
Where:
Draw Reduction (DR) measures the percentage reduction in dimension after a drawing process. It is calculated by dividing the difference between the initial and final dimensions by the initial dimension, then multiplying by 100. This metric is important in manufacturing and engineering to assess the efficiency and effectiveness of the drawing process.
Let's assume the following values:
Step 1: Calculate the Draw Reduction using the formula:
\[ DR = \frac{10 - 8}{10} \times 100 = \frac{2}{10} \times 100 = 20\% \]
The Draw Reduction (DR) is 20%.
Let's assume the following values:
Step 1: Calculate the Draw Reduction using the formula:
\[ DR = \frac{15 - 12}{15} \times 100 = \frac{3}{15} \times 100 = 20\% \]
The Draw Reduction (DR) is 20%.
