Angle vs Height Chart
A simple chart showing the relationship between height and the calculated angle for a fixed length of 100 mm.
User Guide: How It Works
- Place the sine block on a flat surface.
- Insert gauge blocks under one end to raise it.
- The angle formed depends on the ratio: sin(theta) = h / L
- where h is the height of the gauge blocks and L is the length of the sine block.
- Use this calculator to quickly find missing values without manual math.
Frequently Asked Questions (FAQs)
- Q1. What is a sine block used for?
- A: A sine block is used in machining and engineering to set precise angles for inspection or machining tasks.
- Q2. What’s the difference between a sine bar and a sine block?
- A: A sine bar is typically longer and used for angle settings, while a sine block is compact and often used for tool inspection.
- Q3. How do I calculate the height for a 30° angle?
- A: Use the formula: h = L * sin(30°) = L * 0.5
- Q4. Can I use sine blocks for very small angles?
- A: Yes, but small angle accuracy depends on gauge block precision and measuring tools.
- Q5. Are sine blocks still used in CNC machining?
- A: Yes, although CNC machines reduce the need, sine blocks remain essential for calibration and verification.
