Our Mechanical Engineering Team at Jaycon Systems creates, reverse engineers, and tests hundreds of hardware projects every year, so in order to make our lives easier, we came up with a simple 3D printed tool to help measure the various radii (believe it or not that is the plural of radius) of the things we work on. We hope we make your life easier as well by making these files available to the public.

Long or short, straight or curved, deep or shallow, open at one end, both ends or closed, groove geometry dictates the milling method you need. From face milling to side or end milling, Knight Carbide makes the grooving inserts to handle them all.

By reducing cutting depth and increasing spindle speed and feed rate, high-feed milling can significantly increase productivity and tool life. Other benefits include improved chip rates and better surface finish.

IndexableTool

​Take a moment to check the next steps and see how these measurement tools work to measure radius. You will notice that at times an exact measurement cannot be taken as seen in some of the images below — it may be one size too large or one size too small, so the true size will lie somewhere in between.

When your go-to tool for a particular application is suddenly unavailable, you could look around for the next best thing, or you can call Knight Carbide. Time-sensitive, cost-effective, high-quality custom and legacy inserts are a Knight Carbide specialty.

We have used some of the measuring tools available out there, but we have found that most of them aren’t suitable for tight spaces since they have a long handle that doesn’t fit inside the piece we are trying to measure.

Indexableinsert

As we use the 16mm tool instead, we still see a gap on the right side of the tool, which tells us that this tool is slightly too big. We would then feel safe to say that the correct size is an average of the slightly larger and slightly smaller tool at 15mm.

Indexable cutting tools

Knight Carbide, Inc. is a leading manufacturer of precision-ground carbide inserts, indexable inserts and carbide cutting tools.

Our offerings range from product and electronics design to prototyping and manufacturing. We apply our knowledge of technology to most markets, among them consumer electronics, computer hardware, marketing/multimedia, and environment. With our entrepreneurial spirit and as a rapid-prototyping firm, we believe in building products right the first time and introducing them quickly to market. For more, visit jayconsystems.com

Maximize your versatility with a full range of tools for plane or surface milling, end milling, face milling, angle milling, form milling and profiling, all from Knight Carbide. End mills, cutters, saws and bits are all available to your specifications. To further optimize your milling operations, Knight Carbide can alter geometries, grades and coatings to achieve your objectives consistently, affordably and efficiently.

The pieces are as small as 5mm all the way up to 40mm. If you need bigger sizes, you are welcome to make them your own as they are pretty easy to create with a 3D software. We believe that these will get a much closer if not exact radius measurement compared to using a caliper to guesstimate.

Whether you’re milling vertically or horizontally, up or down, a Knight Carbide tool is going to give you the results you want at a price you’ll love.

Measuring rounded edges or corners of an object can be a difficult task. Most people approximate by using a ruler or caliper to measure where the curve starts and where it ends as seen in the first picture with distance A.

The world is filled with millions of different objects all with different shapes, angles, lengths, heights, widths, surfaces, depths, volumes, geometries, etc… You get the point. There are many different ways of measuring all of these different objects. Here we will focus on measuring rounded corners on physical objects. This can be a difficult task without the right tools.

We hope you enjoyed this tutorial and found the tool helpful. If you 3D print your own tool, please snap a picture and hashtag us at #jayconsystems so we can see how useful it was for you!

So in order to fix that problem, we created a set of plastic slivers that look similar to crescent moons. Each piece has the same radius on the inside and outside of the part, so you can measure both the inside or the outside corner radius of a part using the same piece.

In the picture below, you will see that there is a slight gap in the middle of the 14mm tool as we push it on the corner we are trying to measure, telling us this size tool is slightly too small.

Corners located inside a physical object — a small container for example — as seen in the second picture can be even more difficult to measure and estimate. If someone is designing an item to fit up to these measurements, it can become a tedious trial and error game.​

Milling inserttypes

In the high-precision world of OEM parts, skilled crankshaft milling is highly prized. Knight Carbide provides superior cutting inserts for use in all aspects of crankshaft production, including cutting to length, hollow milling, internal and external circular milling, broaching and more.

Jaycon Systems specializes in bringing products to life by offering a complete service line that takes product concepts to mass production.

The STL files are set up as a group and also individually — in case you lose one, you can reprint it separately. Download your STL files here

Sometimes you just can’t find a tool to do exactly what you need. Bring your specifications to Knight Carbide and let our engineers design the optimal insert or inserts to achieve the results you want in the most efficient way possible.

Knight Carbide can control the size of carbide milling inserts to +/- .0002″ enabling tool cutters to run smoother and more efficiently. Our carbide milling inserts are precision-ground to meet a wide range of applications and manufacturing styles including negative, positive, negative-positive, on-edge and form generating.

In the last picture, you see that the 38mm tool is a perfect match to what we are measuring, so we are happy to write down the exact reading of this tool as the radius.
