Sine bar is a simple yet very accurate method to measure the angle of a part. It is built from a precision ground plate sitting on two precision ground cylinders, where the distance between the cylinders is a known whole number.

To set an angle on any sine device, whether it is a sine bar, sine plate, or other sine tool, you must first determine the center distance of the device (C), the angle you wish to set (A) and whether the angle is in degrees-minutes-seconds or decimal degrees.

Explain how to use a sine bar correctly. Understand slip gauge blocks and wringing. Calculate gauge block height. A sine bar is used in conjunction with slip gauge blocks for precise angular measurement. A sine bar is used either to measure an angle very accurately or face locate any work to a given angle.

2024年3月18日 · Sine Bar Calculator; The two work together, but let's focus on how to use them. To calculate gauge block height for a particular angle: Enter your sine bar length (aka "Center Distance"). Common sizes in the US are 5 and 10 inches long. Enter the desired angle. For example, the screen shot shows 5 degrees.

Continuing with my series on angles, here's what sine bars are, how to use them correctly. I'm not remotely finished with this, as I can see that one video offers a lot of explanations but...

2021年3月20日 · Explain how to use a sine bar correctly. Understand slip gauge blocks and wringing. Calculate gauge block height. A sine bar is used in conjunction with slip gauge blocks for precise angular measurement. A sine bar is used either to measure an angle very accurately or face locate any work to a given angle.

1. Set the first of the desired angles ( Angle A ) on the top section of your compound sine plate. 2. Calculate the tangent of the true Angle ( Angle C) using the formula: TAN ( True Angle C ) = TAN ( Angle B ) x COS ( Angle A ) 3. Lookup the True Angle ( Angle C ) in the table of tangents , or use the inverse tangent function on your ...

2020年3月24日 · A sine bar is used either to measure an angle very accurately or face locate any work to a given angle. Sine bars are made from a high chromium corrosion resistant steel, and is hardened, precision ground, and stabilized. Figure 1. The Sine Bar Two cylinders of equal diameter are placed at the ends of the bar.

Set a sine bar angle or sine plate angle with this calculator. Enter the desired angle and sine bar size. The calculator will provide the gage block height.

To set the angles on a compound sine plate, you must first determine the top plate center distance of the device (C1), the bottom plate center distance (C2), the workpiece angles you wish to set (A & B) and whether the angles are in degrees-minutes-seconds or decimal degrees.
