1. What is the Compound Angle Formula?

The compound angle formula sin(C) = sin(A) × sin(B) is used in machining and lathe work to calculate the resulting angle when two angles are combined. This is particularly important for precision machining operations.

2. How Does the Calculator Work?

The calculator uses the compound angle formula:

Where:

• \( A \) — First angle in degrees
• \( B \) — Second angle in degrees
• \( C \) — Resulting compound angle in degrees

Explanation: The formula calculates the sine of the resulting compound angle by multiplying the sines of the two input angles.

3. Importance of Compound Angle Calculation

Details: Accurate compound angle calculation is crucial for precision machining, tool setup, and ensuring proper alignment in lathe operations. It helps machinists achieve the correct angles for complex cuts and shapes.

4. Using the Calculator

Tips: Enter both angles in degrees. All values must be valid positive numbers. The calculator will compute the resulting compound angle C.

5. Frequently Asked Questions (FAQ)

Q1: What is a compound angle in machining?
