So now, we hope that we have clear all your doubts about Sine Bar. To check for unknown angles on heavy components.Some specially designed sine bars are used to mount the workpiece to perform conical-shaped machining for the workpiece.For checking the measurement of unknown angles in the workpiece.The sine-bar is used to set or determine the workpiece at a given angle.Applicationsįollowing are the applications of sine bar: In these cases, the sine bar will be used together with the height gauge for measurement. If the length of the inspected component is too long, there is no sine bar available that is longer than the component.During the measurement of the angle using the sine bar, the sine bar length must be greater than or equal to the length of the component to be inspected.For the construction of slip gauges, there is no scientific approach available and it has to be built on trial and error basis and it is a time-consuming process.Any unknown projections present in the component will cause errors in the measured angle to be induced.Limitationsįollowing are the limitations of sine bar: ![]() This is the formula for sine bar for calculating the angle or setting the workpiece to the required angle. ![]() The above trigonometric formula Sine above = opposite/diagonal = h / Lįrom this we can write θ = sin^-1 (h / L). The distance between the two setting rollers of the Sine Bar is given by L. The one roller is placed on a surface plate and the other is placed at height h by a slip gauge. The two rollers are very precise and highly accurate and are equal in diameter. It consists of two rollers with steel bars. The sine bar is made of high carbon steel, high chromium (corrosion resistance) and hardened.
