An angle gauge measures the angle of a fixed or worked object relative to a larger object. The three most common types of angle gauges are used in forestry, woodworking and engineering. Each of these gauges does the same basic thing; they just do it in totally different ways. In each case, a single object, usually a tree, saw blade or fastener, has its angle checked relative to the larger piece to which it is attached, such as the ground or a work surface.A forester’s angle gauge is used to inventory the trees in a plot of land. These inventories show how many trees of certain sizes are within a given area. This information is used to find areas suitable for harvesting. Buyers require different sizes and types of trees, depending on their businesses; so, using tree inventories is a good way to keep track of growth and diversity within a tract of land.There are a wide range of angle gauge styles used in forestry. The oldest style is still in use today; it looks like a flat piece of metal with a punched-out shape in the form of a step pyramid. Foresters use this simple device by holding the tool a specified distance from their eyes and lining a tree up inside the hole. The forester can tell the tree’s approximate size and its angle relative to the ground. Newer forms of forestry gauges look like prisms, magnifying glasses or small spyglasses.In the engineering, assembly and technical fields, there is a third type of angle gauge. These gauges are used to maintain an even torque load over an area by synchronizing the fasteners across a work piece. After a fastener, typically a bolt, is screwed in tight, it is then screwed in further to a specified angle. If the work piece has several fasteners on the same piece, they are all fastened to the same angle.Angles gauges, like slip gauges are blocks of hardened steel approximately 75mm long and 16mm wide. They differ from slip gauges in the sense that their wringing surfaces are not parallel to each other, but are at an angle, engraved on them. For measuring angles, angle gauges are more accurate than the sine barWhat is the size of angle gauges?
What is the approximate size of angle gauges? Explanation: Angle gauges are about 3 inch (76.2 mm) long and 5/8 inch (15.87 mm) wide. And their faces are lapped within 0.0002 mm.What is the angle of gauge block?

Angle Gauge Block Set: 15 Pieces, 1° to 90° Included Size Range, +/- 2 sec Tolerance. Country of Origin China. Country of Origin is subject to change. Angle gauge blocks are manufactured to a tolerance of +/-2 seconds (1/1800th of a degree).What are the two grades of angle gauges?
What are the two grades of angle gauges? Clarification: Master grade is laboratory standard and made from steel carbide or tungsten carbide. Tool grade is normal industrial purpose angle gauges made from steel.
Angles gauges, like slip gauges are blocks of hardened steel approximately 75mm long and 16mm wide. They differ from slip gauges in the sense that their wringing surfaces are not parallel to each other, but are at an angle, engraved on them. For measuring angles, angle gauges are more accurate than the sine bar. They are enables to measure any angle between 0 degrees and 360 degrees with an accuracy of 0.5 to 0.25 second.Angle gauges are classified in two following categories:

1. Master Angle Gauges:

They also referred as laboratory standard. They are most expensive and have an accuracy of ± 1/4 second.

2. Tool Room Angle Gauges:They are less accurate than master angle gauges. They are less expensive and have an accuracy of ± 1 second.The uses of angle gauges are following:

(i) Quick measurement of angles between two surfaces in engineering industries.

(ii) A frequent use of angle gauges is to check whether the component is within it’s off angle tolerance.(iii) For the measurement of angle more than 90°, by using precision square along with angle gauges.

(iv) Angle gauges are more accurate than sine bar because sine bar involved trigonometric formula.

(v) Procedure of setting angle with angle gauges is less complex than the setting of angle with sine bar.
