Radius Gages Explained

Radius gages are adequately self-explanatory and uncomplicated to utilise. These measurement tools are used on a number of different objects similar hinges, tools, taps, and dies. They are used to measure existing radii, which is a critical operation when information technology comes to applications such equally pattern making, precision machining, layout creation, and role inspection. In this article, nosotros'll explore the main applications in which a machinist would need a radius gage set and break downward how to accurately use the tool. As always, we will wrap up with our top model recommendations.

Radius Gage Anatomy

Information technology is probable that when you lot hear the term "radius gage" you volition also here the term "fillet gage". The different names are oftentimes used interchangeably. It just depends on who are you talking to. They are both used to accept measurements, however their purposes are a bit different. Fillet gages are designed to measure the interior radius of a office while radius gages are designed to measure out the outside radius. This simple departure is depicted in the image beneath.

Because of this primal difference, the term "fillet cuff" is used more frequently in relation to welding and "radius gage" is nearly oft associated with machining projects.

Using a Radius Gage

The most mutual use for a radius cuff set in machining is for checking imperfections similar bumpy surfaces or offcuts of metal debris. For example, information technology can determine if the curvature of a function is the correct shape.

An piece of cake trick to ensure your measurement is accurate: shine a light on the opposite side (from behind) of the object, whatsoever light passing through informs that the curves of the gage and the function take not contacted correctly.  This gage blazon is too great for drawing specific radius measurements direct onto workpieces every bit it helps attain accurate cuts and desired curves when machining.

Radius gages are particularly useful when it comes to inspecting tool and die cast molds. They are used to identify whatsoever set up issues past ensuring die casts have been assembled with the correct radius measurement. This is crucial because the rounded edges of metal molds must exist at optimal precision in order to achieve the structural forcefulness they need.
