Trigonometry: Sine Bar Applications 221

Trigonometry: Sine Bar Applications discusses sine bars and the trigonometry required to use them. Sine bars are used when an angle needs to be machined, measured, or inspected. Sine bars are used with gage blocks to set a workpiece at an angle. To find the necessary measurements for the gage blocks or the sine bar angle, trigonometric ratios are used. These ratios include sine, cosine, and tangent. Gage pins are sometimes used with sine bars and gage blocks to increase the range of measurements. After taking this class, a user should be able to make the necessary calculations for setting up a specific workpiece angle using a sine bar.
