A sine bar itself is a steel bar, made from finely ground or lapped steel, that is typically no wider than 1 inch. At each end of the sine bar is located a precision cylinder that rests against stops machined into the bottom surface. Sine bars can be designed to have upper and lower ends as well as top and bottom surfaces, allowing them to be used in either direction and on either side. In order to hold an object or part in place, there are machined holes along a sine bar into which stops or clamps may be placed. Sine blocks are identical to sine bars, but just slightly wider.
HOW ARE SINE BARS USED IN PRACTICE?
A sine bar and a sine plate are used identically in practice. Using gauge blocks, the sine bar or sine plate is placed at the desired angle, or an angle that matches the workpiece. When placed directly under the upper cylinder, an ABC right triangle prism is formed which then serves as the basis for your measurements. This triangle allows you to apply the sine equation from trigonometry to calculate a range of measurements. This is where sine bars and sine plates get their name
