Using A Sine Bar. 2) locate the work piece to a given angle with very high precision. Rule for determining the height of the sine bar setting for a given angle:
Sine Bar Working Principle. Construction. Formula theengineerspost.com
The sine bar has two round pieces fitted to it so that its effective length is the same at any angle. The sine bar is used to measure angles based on the sine principle. How to set up a sine bara fast example ofhow to set up a sine barsine bar usesine bar angle measurementmetrologysine barsine bar videohow to calculate gauge.
Any unit of length angle desired: Two cylinder of equal diameter are attached at ends the axes of these two cylinders are mutually parallel to each other and also parallel to and equal distance from the upper surface of the sine bar.
The theory and practice of using a sine bar. version 2 by r. The sine bar is the most accurate instrument for measuring angles.
Sine bar is used in conjunction with slip gauges for precise angular measurement. The sine bar is used to measure angles based on the sine principle.
Any unit of length angle desired: The sine bar is the most accurate instrument for measuring angles.
Sine bar is specified by the distance between the centres of two rollers i.e.. 100mm. 200mm. 250mm. or 300mm. two rollers must. Use the sine bar to dial the vice and use an.
Sparber copyleft protects this document.1 the quick answer if you just want to set an angle with a sine bar and stack of blocks. then take the sine of the desired angle on your calculator and multiply the result by the distance between the centers of the cylinders in the sine bar. H = l * sin(θ).
A Sine Bar Is Used In Conjunction With Slip Gauge Blocks For Precise Angular Measurement.
Any unit of length angle desired: When using a sine bar and a sine plate the process is identical. Generally. sine bars are made from high carbon. high chromium. and corrosion resistant steel.
The Sine Bar Forms The Hypotenuse Of A Right Triangle. While The Slip Gauge Blocks From The Opposite Side.
To check for unknown angles on heavy components. The learner will use the deceptively simple sine bar to measure angles to minutes or even half minutes. Theres one to think on.
2) Locate The Work Piece To A Given Angle With Very High Precision.
The sine bar has two round pieces fitted to it so that its effective length is the same at any angle. The name sine bar has come into the picture because the operation of the sine bar is completely based on trigonometry. The aim of a measurement is to make the surface on which the dial gauge or spirit level is placed horizontal.
For Example. To Measure The Angle Of A Wedge. The Sine Bar Is Placed On A Horizontal Surface Plate.
A sine bar is used either to measure an angle very accurately or face locate any work to a given angle. A sine bar is used to measure the angle of the given specimen accurately. The height of the slip gauge block is found by multiplying the sine of the desired angle by the length of the sine bar:

Its upper surface forms the hypotenuse of a triangle formed by a steel bar terminating in a cylinder near each end. Angles are measured using a sine bar with the help of gauge blocks and a dial gauge or a spirit level.
