The formula to calculate the Dovetail Ratio (R) is:
\[ R = \frac{W_t}{W_p} \]
Where:
Let's say the width of the tail is 2 inches and the width of the pin is 1 inch. Using the formula:
\[ R = \frac{2}{1} \]
We get:
\[ R = 2 \]
So, the dovetail ratio is 2.
Definition: Dovetail angles are used to determine the slope of the dovetail joint, which affects its strength and appearance.
Formula: \( \text{Angle} = \arctan\left(\frac{\text{Rise}}{\text{Run}}\right) \)
Example: \( \text{Angle} = \arctan\left(\frac{1}{6}\right) \)
Definition: This calculator helps determine the dimensions of a dovetail groove for an O-ring to ensure proper fit and sealing.
Formula: \( \text{Groove Width} = \text{O-Ring Diameter} + 2 \times \text{Clearance} \)
Example: \( \text{Groove Width} = 5 + 2 \times 0.5 \)
Definition: Dovetail milling cutters are used to create dovetail slots and grooves in materials.
Formula: \( \text{Cutter Diameter} = \text{Shank Diameter} + 2 \times \text{Cutting Depth} \)
Example: \( \text{Cutter Diameter} = 10 + 2 \times 2 \)
Definition: Using dividers to layout dovetails ensures consistent spacing and alignment without the need for measuring tools.
Formula: \( \text{Spacing} = \frac{\text{Board Width}}{\text{Number of Tails}} \)
Example: \( \text{Spacing} = \frac{30}{5} \)
