Chord Formula:
| From: | To: |
The chord formula calculates the straight-line distance (chord length) between two points on a circular saw blade's circumference, given the blade radius and central angle. This is particularly useful for determining kerf width and blade positioning.
The calculator uses the chord length formula:
Where:
Explanation: The formula calculates the length of the straight line connecting two points on the circumference of a circle, which is essential for precise saw blade positioning and kerf calculations.
Details: Accurate chord calculation is crucial for determining the kerf width of saw blades, setting up precise cuts, and understanding the geometry of circular saw operations.
Tips: Enter the blade radius in inches and the central angle in degrees. Both values must be positive numbers (radius > 0, angle between 0-360 degrees).
Q1: What is chord length in saw blade terms?
A: In saw blades, chord length represents the straight-line width of the cut (kerf) at a specific point along the blade's circumference.
Q2: How does blade radius affect chord length?
A: Larger radius blades will produce longer chords for the same angle, meaning wider kerfs at equivalent cutting angles.
Q3: What's the practical use of this calculation?
A: It helps woodworkers and metalworkers understand and predict the cutting behavior of their circular saws, especially for angled cuts.
Q4: Does tooth configuration affect this calculation?
A: While tooth configuration affects cutting performance, this calculation deals with the fundamental geometry of the blade itself.
Q5: Can this be used for other circular cutting tools?
A: Yes, the formula applies to any circular cutting tool (hole saws, rotary cutters, etc.) where you need to calculate chord length.
