PRI 2017 Show Highlights

3/13/2018

by Bernard Martin

At the 2017 Performance Racing Industry show held in Indianapolis,IN we where very excited to tool up the new Centroid A590 Engine Shop CNC Machine. Our end mills where also used in the Palmgren booth on a manual milling machine and we met some great customers and exhibitors at the show who told us about their experiences using Destiny end mills. Theres a complete video below of many of the highlights from the show.

We where able to connect with the folks from Centroid in Howard, PA to provide some tooling for their new Centroid A590 Engine Show CNC Machine.

A complete turn-key system, the A590 Machining Center overcomes many limitations of other cnc porting machines with its unique and patented technology. With Centorid's advanced technology you can machine cylinder heads and engine blocks to incredible tolerances while maintaining amazing surface finishes all with one machine.

Centroid's CNC articulating head was designed specifically for CNC Cylinder head porting. Made in the USA of rigid cast iron the A590’s B axis rotates 90 degrees in each direction for a full 180 degrees of movement of the tilting B axis spindle head/

Video Highlights:

Check out our interview with Mike Stevens from Centroid talking about the new A590 using a 5/8" diameter Destiny Tool Diamond Back at 11,000 RPM, 240 IPM, .060" radial, and .500" axial.
Jeremy Harshman, at 17 year old high school senior updated us on what he's been doing since we met him last year at PRI when his father bought him his first CNC Mill. He shows us an intake elbow for a Terminator Mustang all made with Destiny End mills. You can following him on instagram @motivperformanceengineering
Rob Stock was kind enough to send us some of his parts made with Destiny End Mills for display inner booth. You can check him out on instagram @stock_design
Dean visited us lat year at PRI and was just getting his new Haas VF5 CNC milling machine. He updates us on what he's been up to in the past 12 months since we last met and they finishes he getting with our end mills.
There a close up up hyperlaspse in the video of the Destiny Raptor 3/6 end mills for those who have been asking for that 360 degree view.
Alec Darling from J Squared swung by our booth. J Squared had their own booth just down the aisle from us. Alec overheard some of our conversation and made some great comments that we just had to get him on video saying. J Squared started 35 years ago and made quite a name for themselves by manufacturing high-quality, affordable tubing benders and notchers and now plasma cutting tables. You can follow them on instagram @jsquaredinc
The Pitt SAE Race team who we sponsor was kind enough to assist us in the booth for set up and break down. You can follow Panther Racing @PittFSAE

Understanding Transverse Rupture Strength (TRS)

3/15/2017

0 Comments

by Bernard Martin, Managing Director Sales & Marketing, Destiny Tool

For anyone who has been using carbide end mills for a while you have undoubtedly heard the term "Transverse Rupture Strength" or "TRS." Transverse rupture strength (TRS) or "bending strength" testing is the simplest and most common way of determining the mechanical strength of carbide end mills.

Transverse rupture strength (TRS) also known as "modulus of rupture", "bend strength", or "flexural strength". It's a material property, defined as the stress in a material just before it yields in a TRS test. Simply put, It's the point just before it breaks and shatters. If you have every had an end mill break in half, you have exceeded the TRS value.

When an carbide end mill is "bent" (Fig. 1), it experiences a range of stresses across its depth (Fig. 2). At the edge of the object on the inside of the bend, B, (concave face) the stress will be at its maximum compressive stress value.

At the outside of the bend, A, (convex face) the stress will be at its maximum tensile value. These inner and outer edges of the carbide rod are known as the 'extreme fibers'.

Most materials fail under tensile stress before they fail under compressive stress. If you break a pencil in half it doesn't crack close to you but awn from you. The maximum tensile stress value that can be sustained before the rod fails is the transverse rupture strength (TRS) of a given grade of carbide rod.

Longer endmills shoud have a higher TRS value

The Standard method of measuring TRS is with a square material sample, as shown in Fig 1, of a given length and supported at both ends with a force, the yellow arrow above, exerted on the bar stock. It's done according to the standardized method EN 23 327 (ISO 3327):

"a specimen of a specified length with a chamfered, rectangular cross section is placed on two supports and loaded centrally until fracture occurs. TRS is taken as the median of several observed values."

The carbide rotary toolmaking sector has adopted a modified TRS testing method that is more applicable to the geometry of solid carbide rods. In this test a modification of the standard test specimen according to EN 23 327 (ISO 3327) is used.

This test comprises a cylindrical carbide specimen, Ø 3.25 x 38 mm. This modified test has been adopted as an industry standard and is now proposed to be included in the ISO standard.

By using this cylindrical test specimen, as used to make carbide rotary end mills, the edge effect of the rectangular standard specimen is avoided.

NOTE: Higher TRS values increase the TOUGHNESS of the tool: it will "bend" a bit more before catastrophic failure, but you sacrifice WEAR RESISTANCE when you increase toughness. More on that below...

Why TRS is important

Take a look at the picture of the two end mills in the above section. If you are using a longer overall length (OAL) end mill, the longer tool will be more prone deflection when it's in-the-cut and under load.

It's essentially the same effect if you try to push too hard on the head of a pencil point. If you apply too much pressure, it will eventually break and lead to catastrophic failure of the tool. Ideally, the longer the reach of the tool the higher your would prefer the TRS value.

It's important to keep in mind that it's really about a carbide rod length to diameter ratio, The longer the overall length of the tool, when compared to cutting diameter, the more important the TRS becomes.

Because of this, the TRS value is also very important to understand when using miniature end mills. Higher TRS values enable you to take a heavier cut (chip load per tooth) without catastrophic failure of the tool.

TRS values are more critical with longer length to cutting diameter ratios.

How you increase the Transverse Rupture Strength

Carbide end mills are a form of powdered metal. In simple terms, Carbide rod is created by mixing Tungsten Carbide powder (WC) with a binder, Cobalt (Co). It is extruded into a carbide rod and then, under heat and pressure, sintered into end mill rod stock. By increasing the cobalt content, you will increase the TRS value and "toughness" of the tool. e.g. it will 'bend" more, but it will also dramatically reduce the wear resistance of the carbide. Cobalt is just not as wear resistant as carbide. That's why cobalt end mills wear out quicker than carbide end mills.

The TRS reaches a maximum at cobalt content of about 15% (by weight) and a medium to coarse Tungsten Carbide WC grain size. Typically, the cobalt content of an end mill ranges between 8-12% (by weight) of the carbide in most end mills.

It's important to know that the cobalt content of a carbide end mill is measure by weight and NOT volume.

Think about mixing up a cake. You pour your milk into a measuring cup based upon the VOLUME of milk you need. In contrast, when mixing carbide rod, you MEASURE THE WEIGHT of the carbide and the WEIGHT of the cobalt on scale for the proper mix.

Carbide weighs A LOT more than Cobalt! To see this for yourself hold a cobalt end mill in one hand and a carbide end mill in the other. Because Cobalt weighs much less than Carbide it takes up MORE VOLUME: It's a bigger pile as you increase the percentage of cobalt.

It bears repeating, Carbide substrate is measured by weight.

If you where to measure the VOLUME of the cobalt in a 12% Cobalt (by weight) carbide end mill, that volume may be as high as 24-28% (depending on the grain size of the carbide). That's the reason for the reduced wear resistance of the higher cobalt content but also the reason that those end mills have a higher TRS value and greater "toughness"

For a much more detailed breakdown of carbide substrates and how carbide is made please take a look at our technical section at this link: CARBIDE SUBSTRATE.

The latest video from our instagram #DestinyTool hashtag;

"I am Peter, the owner of Precision Machinery & Tooling in Pearl City, HI. This has been one of our more popular vids. Had a nephew goofing around with a #gopro and took this sequence.

The material is 2" round A-36 hot rolled, initially machined in another mill for the shank. Then in the 4th axis on this mill with a parametric program to index a small amount, make sure we are not done yet, and take another pass till math says we are done. The opening operation gashes the part to profile, then it indexes the last pass all the way around.

We are def a mill shop so we don't get around to repairing lathes like we should...."

We had to get 50 of these weld on pipe tips out. 4th axis and a parametric program knock them out. 1/2" 6 fl destiny endmill.

We used a DestinyTool Raptor, 1/2", 3/6 flute, approx 3/4 - 1" loc 2800 rpm, mist coolant, 50 ipm on approx .035 to .05 doc. started with a tired one, got about 2/3rds of the way through, changed to new and ran way past that job.
