A radius gauge is an inspection gauge that inspects the corner R (roundness of radius) of a workpiece.
By placing the radius tip of the gauge along the measurement section of the workpiece, it checks if the standard radius dimensions have been achieved.
Since the gauge is compared with the part to be inspected visually, no measurement value can be output. If you need measured values, you can use a contour measuring machine, etc., to measure the shape of the workpiece, and then measure and analyze the shape of the relevant section to output the measured values, but a radius gauge is less time-consuming and is inexpensive.
Radius gauges can be used to check the corner radius of a workpiece relatively easily.
For example, in the turning process, when a single shaft has multiple O.D. surfaces and each O.D. surface has a radius surface at the joints, it is possible to check whether the specified radius surface was met before removing the workpiece after machining of the relevant part is completed.
In addition, even if the workpiece cannot be moved and is inside a relatively complicated structure, such as a pipe that has already been installed, the radius gauges can be used to check the radius dimension of the outside diameter by aligning it with the gauge.
Radius gauges are thin-film plates with a predetermined radius profile molded into the end of the plate, which can be convex or concave, and of various dimensions. The relevant dimensions are indicated on the plate.
The radius of the tip can be checked for the specified radius by placing the radius along the measurement section of the workpiece.
In some cases, a matching material such as brew paste may be used to check the conformity between the gauge and the workpiece. However, since the results may vary depending on whether the mortiser needs to be removed after the inspection and on the degree of application of the blue paste (film thickness of the paste), it is necessary to examine the necessity and establish a standard work rule for implementation.
In order to make comparative measurements with gauges, it is necessary to confirm the specified R dimensions indicated on the gauges, and it is necessary to use the same gauges many times to check for wear and deformation of the gauges before inspection. It should also be noted that when brew paste is used, it wears faster than when not used.
While contour gauges are accurate and can output measurements, radial gauges have a very simple shape and are easy to use, so it is advisable to consider what kind of results are needed before using them.
