Cut 3 ended up being a much closer race than the metal removal rate calculation predicted. The 12-mm solid tool’s calculated metal removal rate of 2.41 cubic inches per minute was 42% better than the ½ inch indexable cutter’s 1.70 in3, but the cycle time ended up being only 3% shorter. Again, we can attribute this to the high feed tool staying in the cut longer. The high-efficiency tool taking a trochoidal tool path is constantly moving in and out of the cut and results in the cycle time being longer than predicted by the metal removal rate.

Although both rail systems have had their share of popularity among shooters, you’re more likely to find a Picatinny rail on modern firearms. The widespread popularity of the Picatinny rail can be attributed in part to the U.S. Military’s adoption of the rail in 1995, but also because the uniformity and consistent spacing make them a better option for swapping out accessories between guns.

Simply stated, this difference means an accessory designed for a Weaver rail will fit into the wider Picatinny rail slot. However, accessories designed specifically for the Picatinny rail system will have notches that are too wide to fit the narrower Weaver spacing. The difference is quite small, and if you are handy with a file or Dremel tool, you might get it to fit.

High feed milling with an indexable tool is pretty much the opposite. Here, you are primarily cutting with the end of the tool where the inserts are, and at a shallow depth of cut. The chip thinning principle is applied here too, though now in the axial direction.

At Carnegie Mellon University’s Manufacturing Futures Institute, researchers use a robotic test bed where AMRs deliver Lego bricks to robot arms for assembly to study AI, multirobot collaboration, assembly, safety and more.

Lights, scopes, and foregrips are just a few of the accessories that we commonly mount to our guns, and most manufacturers now offer a variety of accessory mounting options on base-model guns.. Mounting systems that incorporate slotted rails, like the Picatinny and Weaver rails, are extremely popular and even come standard with many firearms. So what’s the difference between Picatinny Rails vs. Weaver rails?

Pacon Mfg, Inc. has not rested on its laurels as the 2020 Top Shop Honoree for Shopfloor Practices and Performance. In the years since, it has refined its processes to continue excelling in a volatile market.

The design originated to facilitate the mounting of a scope on high-powered hunting rifles. With the military standardization in 1995, the popular M16A2 and M4 carbine version of military rifles were modified to begin including the Picatinny rail as standard equipment. Rails can be designed for the front handguard on these rifles in multiple positions (top, bottom, right or left side).

The reason that high-efficiency milling wasn’t used more in the past was that toolpaths were difficult to program under differing tool engagement situations such as edge cutting vs cornering inside a pocket. However, several CAM systems today dynamically adjust feeds and speeds for any situation to maintain a constant chip load throughout the cut. Multi-flute cutters have also become available—such as the Kyocera 12 mm 9-flute and 6-flute endmills used in these cutting tests—that are more efficient simply by getting more edges into the cut per revolution, and that enhances tool life and surface finish.

Working closely with customers and making careful investments has enabled this Wisconsin machine shop to tackle difficult jobs with tight deadlines as a core part of its business.

High-efficiency milling has gotten a lot of attention in recent years as a way to substantially increase metal removal rates with solid carbide end mills on almost any kind of milling machine. With small stepovers, but faster feed rates and deeper depths of cut, this “constant chip load” cutting strategy can dramatically increase roughing efficiency compared to conventional machining.

The first shouldering cut shown in the video below is pretty straightforward. With a 1-inch, 5-insert indexable cutter compared to a 12-mm, 9-flute solid carbide endmill, their respective metal removal rates indicate that the solid tool should take roughly 2.3 times as long to machine the form as the high feed cutter, and the actual time reflected this. Note that the high-efficiency process typically only uses climb milling, which is why you see the tool constantly feeding in one direction.

When Puneet and Neelam Neotia moved from India to the United States several years ago, they brought with them a family background in manufacturing and CNC machining.

Cut 4 confirmed that the 1” high feed cutter showed an advantage that wasn’t as large as the metal removal calculation predicted. In this case, the high feed cutter made a lot of non-cutting moves to return to center and also ended up not maximizing the width of cut due to the pocket geometry. In contrast, the high efficiency toolpath allowed the solid carbide tool to stay in the cut a higher percentage of the time and allowed it to close the time gap.

Some manufacturers include an accessory rail, but don’t use the Picatinny design. For instance, Glock handguns have their own proprietary rail design that is not interchangeable with the Picatinny rail. Luckily, many companies have designed their products to be compatible with both Picatinny rails and Glock rails.

Because the cutting force is reduced, you can mill with a much larger depth of cut with a solid end mill, plus get better utilization of the full side of the tool. Bottom line, this method can increase metal removal rates by 50% or more compared to conventional roughing, yet still deliver better tool life. What’s great about this process is that it works on virtually any machining center.

In addition to rifle and shotgun applications, the Picatinny rail can also be found on some handguns. Many handguns, particularly rimfires, feature a Picatinny rail along the top of the slide. This allows for the mounting of a red dot optic. Most medium to full-size handgun manufacturers include a Picatinny rail built into the bottom front portion of the frame. This is widely known as an accessory rail. Weapon lights and laser sights are the most common items mounted to handguns using this rail system.

The new space includes a showroom, office spaces and an auditorium that will enhance its work with its technical partners.

Kyocera’s conclusions from these tests are that for lighter axial depths and a larger radial depth of cut, the high feed cutter will have an advantage. For heavy axial and light radial cuts, the solid tools will be a better choice. From a programming standpoint, maximizing the time cutting metal and reducing non-cutting moves will naturally reduce cycle times, further providing cost saving benefits. Past experience has shown that both methods (high efficiency and high feed) are ultimately effective in improving tool life over conventional machining methods.

A Picatinny rail has specific dimensions of grooves and notches and is built into a handgun or long gun to mount different attachments. It’s sometimes called a “Pic Rail” and is exactly the same thing as a MIL-STD-1913 rail.

Cut 2 resulted in the high feed cutter having a shorter cycle time while the metal removal rate showed that the solid tool should have been faster. You can see in the video that the high feed cutter is both climb and conventional milling, so it stays in the cut a higher percentage of the time. Since the solid endmill is only allowed to climb mill, there is a lot of time wasted feeding back around to the start of the cut. However, in both Cut 1 and 2, the solid cutter does provide a significantly better surface finish.

Determining whether to use high-density fixtures or to simplify workholding requires a deeper look into the details of your parts and processes.

High-efficiency milling is based on the “radial chip thinning” theory that’s been around for a long time. The basic idea is to keep the tool cutting at an ideal chip load. To increase the metal removal rate, the stepover is substantially reduced from the typical 50% of tool diameter, but the feed rate is increased in order to maintain the correct chip thickness.
