1. What is Radius of Round Corner?

The radius of a round corner is a radial line from the focus to any point of a curve. It represents the distance from the center of the circular arc to the arc itself, defining the curvature of the rounded corner.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ r = \frac{l_{Arc}}{\left(\frac{1}{2}\right) \times \pi} \]

Where:

\( r \) — Radius of Round Corner (m)
\( l_{Arc} \) — Arc Length of Round Corner (m)
\( \pi \) — Archimedes' constant (approximately 3.14159)

Explanation: This formula calculates the radius of a circular arc when the arc length is known, based on the relationship between arc length and radius in circular geometry.

3. Importance of Radius Calculation

Details: Calculating the radius of round corners is essential in various engineering and design applications, including architecture, manufacturing, and product design, where precise curvature measurements are required for proper fitting and aesthetic purposes.

4. Using the Calculator

Tips: Enter the arc length of the round corner in meters. The value must be valid (arc length > 0).

5. Frequently Asked Questions (FAQ)

Q1: What units should I use for the arc length?
A: The calculator uses meters as the default unit, but you can use any consistent unit of length as long as you maintain consistency throughout your calculations.

Q2: Can this formula be used for any circular arc?
A: Yes, this formula applies to any circular arc where the arc length represents exactly half of a full circle's circumference.

Q3: What if my arc length represents a different fraction of a circle?
A: For arcs that are not exactly half-circles, a different formula would be needed that accounts for the specific central angle of the arc.

Q4: How accurate is this calculation?
A: The calculation is mathematically precise based on the input values. The accuracy depends on the precision of your arc length measurement.

Q5: Can I use this for both interior and exterior rounded corners?
A: Yes, the formula works for both concave and convex rounded corners, as long as the arc represents a circular segment.
