What is Understanding Metrology and Measurement Tools about?

Here are the steps to set up the sine bar at 30° and determine the height h: 1. Place the sine bar on a surface plate so that its surface is parallel to the surface plate. 2. Place one roller of the sine bar against the angular surface whose angle is to be measured. 3. Place gauge blocks under the other roller until the bar surface is parallel to the angular surface. 4. The height of the gauge block stack is the perpendicular distance h. 5. Use the formula: Sin θ = h/L 6. For a 30° angle and a sine
