Radius Gauges

1 - 10 of 8

Which of the following is another name of radius gauge?

Discuss
  • Fillet gauge is another name of radius gauge.
  • It is a precision measurement tool used to measure the radius or fillet of a curved surface or object.
  • The gauge typically consists of a series of blades or leaves, each with a different radius size marked on it.
  • The user selects the appropriate blade that matches the curve being measured, and places it against the object to determine its radius or fillet size.

The measuring range of radius gauge is

Discuss
  • The measuring range of radius gauge is 0.00075-0.025 m.
  • Set 1, with a measuring range of 0.6-0.8mm, is useful for measuring small radii that may be found in precision machining or toolmaking applications.
  • Set 2, with a measuring range of 1-7mm, covers a broader range of radii and may be used for measuring the radii of larger objects or components, such as pipes or tubing.
  • Set 3, with a measuring range of 6mm-25mm, covers an even larger range of radii and may be used for measuring the radii of larger components or objects such as cylinders or spheres.

Which of the following is not a type of radius gauge?

Discuss
  • Planer is not a type of radius gauge.
  • A planer is a woodworking machine that is used to create flat surfaces on wood by removing small amounts of material with each pass of the tool.
  • It works by passing a cutting blade over the surface of the wood in a linear motion, which removes any high spots and leaves a smooth, flat surface behind.
  • In contrast, a radius gauge is a precision measurement tool used to measure the radius or fillet of a curved surface or object.
  • It typically consists of a series of blades or leaves, each with a different radius size marked on it.
  • The user selects the appropriate blade that matches the curve being measured, and places it against the object to determine its radius or fillet size.

Which of the following option is incorrect with respect to radius gauges?

Discuss
  • If the curved surface is external then this radius is known as the female radius" is incorrect with respect to radius gauges.
  • In general, when referring to the radius of a curved surface, the term "male radius" is used to describe an external radius, while "female radius" is used to describe an internal radius.
  • So if the curved surface is external, then the corresponding radius would be referred to as the male radius, not the female radius.

The individual blade of radius gauge is also called as

Discuss
  • The individual blade of radius gauge is also called as Leave.
  • The user selects the appropriate leaf with the closest matching radius to the curve being measured, and places it against the object to determine its radius or fillet size.

Why a radius is provided at the meeting point of two surfaces?

Discuss
  • To avoid stress concentration a radius is provided at the meeting point of two surfaces.
  • Stress concentration occurs when there is a sudden change in shape or geometry, such as at the point where two surfaces meet at a sharp angle, and can lead to localized high stresses that may cause failure or other problems.
  • By adding a radius at the meeting point, the stress is distributed more evenly over a larger area, reducing the likelihood of stress concentration and improving the overall strength and reliability of the component.

The material used in the radius gauge is/are

Discuss
  • The material used in the radius gauge can vary depending on the specific application and requirements, but commonly used materials include stainless steel, plastic, and acrylic.
  • Stainless steel is a common choice for radius gauges as it is durable, corrosion-resistant, and can be easily machined to produce precise and accurate measurement tools.
  • Plastic and acrylic materials may also be used for radius gauges, especially for applications where a lightweight and portable tool is needed.
  • These materials are less durable than steel, but can still provide accurate measurements and may be more suitable for certain applications where weight and ease of use are important factors.

The application of radius gauge is/are

Discuss
  • Radius gauges are commonly used in pattern making to ensure that the correct radii are used in the pattern, and to check that the finished pattern matches the design specifications.
  • They are also commonly used for final inspection to verify that a finished product or component meets the required specifications and tolerances for its radii or fillet dimensions.
  • Radius gauges can be used to check for imperfections such as surface defects or irregularities, and to ensure that the radii and fillets on a workpiece are consistent and free from any sharp edges or corners that could lead to stress concentration or other issues.
