The MarSurf CD 140 AF is designed to measure many different kinds of workpieces, making it suitable for a wide range of measurement tasks.

“There’s a wrinkle in this scenario that is often overlooked or misunderstood,” Mr. MacArthur warns. “It’s the roundness of the tool shank.” A tool shank manufactured to a very high level of roundness complements and enhances the benefits of super-accurate, high-quality toolholders. This roundness directly affects its degree of contact with the clamping surface of the toolholder. The roundness of the tool shank and the quality of the toolholder go hand-in-hand, but most discussions of toolholder requirements neglect the importance of using tools with exceptional roundness. (According to Mr. MacArthur, the tool shank on a RobbJack end mill for titanium is produced to a roundness of 0.000025 of an inch.)

Though most frequently used for diameter measurements, an air plug and platen can be readily configured to measure perpendicularity.

What is significant here is that the rigidity and torque requirements for machining with these parameters do not demand the capability of a large “titanium machine,” but are achievable with many vertical machines produced within the last five or six years. “The latest generation of 40-taper machining centers are more rigid and capable then preceding models, because builders are applying finite element analysis and other advanced design tools,” Mr. MacArthur explains. Thus, a well-maintained, newer machine is a candidate for titanium machining.

CoroMill MS 20 is designed for repeated shoulder milling, face milling, linear and helical ramping, full slotting and plunging applications.

Because end mills with a diameter of ½ inch or smaller are the best fit for the power and rigidity profiles of a 40-taper machine, four-flute end mills are a good choice for heavier cuts and for pockets with many tight corners. Settings that generate 125 to 200 sfpm at a 15-ipm feed rate are average for a four-flute end mill. Stepovers in X and Y that are as much as 25 percent of the tool diameter are acceptable here.

In the latest episode of our View From My Shop series, MMS Editor-in-Chief Brent Donaldson visited the JN Shapiro Watches headquarters and production facility where Founder Joshua Shapiro—a history teacher turned watchmaker—realized his dream of "making a watch from scratch and everything in it."

To put some representative numbers to this concept, he describes the following sample test part. A block of 6Al4V titanium (6 by 4 by 1.5 inches) was machined (roughing and finishing) with a ½-inch-diameter cutter with six flutes. The feed rate was 75 ipm and 400 sfpm. Radial depth of cut was 0.05 inch—10 percent of cutter diameter. Axial depth was 1 inch (two times cutter diameter). In this example, approximately 22 cubic inches of material was removed in slightly less than 15 minutes. To give perspective to the metal removal potential indicated here, Mr. MacArthur adds that, in a strictly roughing operation using this approach, a 1/2-inch-diameter cutter is capable of removing more than 65 cubic inches of 6Al4V titanium in 15 minutes.

Regardless of the supplier, end mills suitable for machining titanium may have four (or fewer) flutes and as many as 10 (or more). “Many shops get stuck when deciding the best number of flutes for titanium work on a general-purpose machining center,” Mr. MacArthur says. “Advice from a supplier on this choice can seem a bit mysterious, especially if the shop is new to titanium machining.”

Perhaps the most important way to protect the cutter when machining titanium is to provide tool paths that avoid conditions that overheat the tool and degrade the cutting edges. For milling pockets and wide slots, this can be accomplished by using toolpath algorithms that maintain a constant angle of engagement between the cutter and the workpiece. Today, most of the CAM software developers offer such algorithms, under a variety of names. All of them create a tool path that restricts how much of the tool radius can be in contact with the workpiece at any time. In a slot, such a tool path will usually follow a regular trochoidal pattern. The tool moves in a series of uniform curves from side to side as it forms the slot. The uniform arcing of these moves is rather easy to see, Mr. MacArthur asserts.

“Regardless of the type of machine tool a shop has for milling titanium, the principles of milling titanium are the same. What have changed in recent years are the options available for controlling variables that these principles are based on,” Mr. MacArthur says. These options create choices that are appropriate for milling this metal on many existing machining centers, he goes on to say.

However, a shop with a 40-taper vertical machining center in sound condition should not rule out this manufacturing resource for effectively and profitably milling titanium. Mike MacArthur, VP of engineering and a titanium expert at cutting tool manufacturer RobbJack, has been promoting this point for a while now. Importantly, he does not take a purely cutting-tool-centric view of this proposition, although cutting tool considerations naturally become a focal point, simply because a systematic approach to milling titanium revolves around managing the conditions that enable an end mill to remove this tough material efficiently.

Q-Mark has built its metrology business by providing what customers need, when they want it. This goes for its IMTS booth, too, with free drinks alongside custom technology.

For example, toolpath algorithms that ensure constant engagement of the cutter in the workpiece material are especially effective—and necessary—in titanium. Super-accurate toolholders with highly concentric, rigid gripping force address another requirement for titanium machining. A high-pressure coolant delivery system on a machine is advantageous. Of course, the range of end mills designed for various machining operations in titanium are now well developed and available from many cutting tool manufacturers.

Manufacturers continue to feel the pressure to reduce costs, increase efficiencies and meet their sustainability strategies. As the industry evolves to keep pace with these priorities, there are opportunities within metalworking processes to use less resources with advanced lubricants and technical expertise. Agenda: An overview of metalworking lubrication Evolutions in metalworking lubrication Experience on the shop floor Key takeaways

Super-accurate, high-quality toolholders are a must for milling titanium. The quality of the toolholder influences a machining operation in several ways. Secure clamping in the machine tool spindle enhances rigidity of the entire cutting tool assembly. The accuracy of the toolholder minimizes runout and contributes to consistent conditions when the tool is in the cut. Well-balanced toolholders reduce stress on the machine spindle and on the cutting tool, while also reducing causes of vibration. Super-accurate toolholders provide higher gripping force on the cutting tool, too. Because milling titanium creates higher cutting forces than milling softer, freer cutting materials, the gripping power of the toolholder is critical.

Horn USA’s new booth concept is designed to enable attendees to (literally) get a better feel for its various tooling offerings.

Of course, strong, sharp edges are not the only design characteristic that cutting tool manufacturers give to end mills for titanium. Common design principles include uneven flute spacing to break up harmonics that can induce chatter; helix angles that vary from flute to flute for chip flow; and a coating that is smooth, slick and slow-wearing to reduce frictional heat. Eccentric relief along the cutting edges is also typical, because it supports and strengthens the cutting edges, which are ground and polished for sharpness.

Roundness of the tool shank is especially important with small-diameter cutting tools, because the area of contact between the cutting tool and holder is proportionately smaller. Any loss of contact reduces gripping force significantly.

This presentation focuses on the vital role that linear and angular encoders play in ensuring precision in machine tools. Attendees will learn about the common challenges compromising accuracy, such as thermal expansion, mechanical misalignments and vibration.

When applied to an irregularly shaped pocket, the toolpath algorithms create a pattern that may be much harder to discern because it does not seem to reflect the shape of the pocket’s sidewalls at first. In fact, that tool path is designed to avoid burying the cutter in corners or during sudden changes in direction by removing material with a progressive series of circular and arcing moves. Although the offerings from different CAM developers may vary in terms of significant nuances or speed of processing, they all provide a similar benefit when machining titanium—the ability to use a smaller-diameter cutter at smaller stepovers and at higher tool rotations per minute.

So far, Made in the USA has looked into system-wide effects of broken supply chains, automation, skilled workforce issues and our perception of manufacturing jobs — examining each topic through a prism of individual experiences. For this final episode for Season 1, let’s look at one more system-wide question and bring it back to personal perspectives: Is there today a new dawn, a new moment for American manufacturing?

This article suggests that a practical approach to milling titanium enables shops to consider the capability of existing machining resources such as a newer VMC. The approach is practical because suitable choices in cutting tools, toolholders, CAM software and so on are readily available.

End mills for titanium usually have thick cores to resist deflection, so the channels between the flutes are not especially commodious. However, they are adequate when light cuts produce thin chips that can be flushed up and out. This is true even for six- and eight-flute styles in which space for chip flow is especially tight. In short, copious amounts of coolant at high pressure (as high as 1,000 psi) greatly reduce opportunities for chips to become trapped between flutes.

Using a smaller tool reduces the contact between the cutting edges and the workpiece surface. As a result, less heat is absorbed by the tool. This strategy requires a programmed tool path and the proper speeds and feeds that enable this smaller tool to remove material efficiently.

Job shops are implementing automation and digitalization into workflows to eliminate set up time and increase repeatability in production.

Where permissible, however, using a six- or eight-flute end mill of a comparable diameter is a good choice for open, rectangular pockets, because applicable speeds and feeds typically reach 400 sfpm. This makes this tool very productive. The corresponding feed rates of 45 to 75 ipm are indicative of this potential. Six-and eight-flute end mills perform especially well when constant-engagement tool paths can be applied. Stepovers in X and Y will range from 2 to 10 percent of diameter in this case. High-speed finishing cuts that leave a smooth surface are also an ideal operation for this type of tool.

The background to any discussion of titanium milling has to cover the issue of heat. “It is a primary consideration in crafting a strategy for milling titanium on any machine, but especially so for general-purpose machining centers,” Mr. MacArthur says. Excessive heat can quickly damage the cutting edges of an end mill and thus undermine the “support structure” built into the rest of cutting strategy. Titanium needs a strong, sharp cutting edge, because a clean, shearing action enables this material to form chips that leave a superior workpiece surface, absorb heat and flow up the flutes smoothly.

“This is not to say that all titanium end mills are created equal,” Mr. MacArthur cautions. RobbJack, for example, applies its own proprietary concepts and innovations to end mill design. The differences may be subtle as well as significant, so shops should look closely at a supplier’s offerings, he advises.

Weldon Solutions is demonstrating three grinders at IMTS 2024. Though they differ in size and use case, all feature the company’s hallmark customizations.

Choosing the number of flutes is best understood as it relates to the strategy of managing how much contact each flute has on the surface of the workpiece. In situations where the flutes are more likely to be in contact with the surface, a smaller number of flutes is preferred. In situations where the flutes are less likely to be in contact, a larger number is preferred.

Metalworking coolant has three functions: It provides cooling, lubricity and chip control. All three functions are valuable when milling titanium. Most of today’s machining centers have coolant delivery options that benefit titanium milling. Having a high-pressure, through-the-spindle capability is best, because it is the most effective for promoting chip evacuation. Additional coolant ports and “showerheads” are also recommended.

The L.S. Starrett Co. has been manufacturing precision measurement tools in Athol, Massachusetts, since 1880.

As the demand for faster production cycles continues to grow, the ability to produce high-quality parts quickly and efficiently has become increasingly important. High-speed 3D printing has emerged as a key solution to reduce lead times and increase productivity across industries. However, like any advanced technology, it comes with its own set of challenges. In this webinar, Forward AM will explore both the opportunities and hurdles of adopting high-speed printing with a particular focus on overcoming those challenges. It’ll start by discussing the fundamentals of high-speed 3D printing and how it differs from conventional 3D printing methods. It’ll then move on to the key factors that influence successful implementation, including the impact of materials, equipment and design considerations. One of the main hurdles in high-speed 3D printing is ensuring the right balance between speed and part quality. Different materials behave differently under high-speed conditions — and not all equipment is optimized for this process. Forward AM will showcase some validated materials and equipment that are proven to perform well under these conditions. In addition, the presenters will look at real-world examples and applications where high-speed 3D printing has been successfully implemented, highlighting the collaboration between designers, engineers and manufacturers. By the end of this webinar, you'll not only have a clearer understanding of high-speed 3D printing with FFF but also the practical steps and considerations needed to make the most of this cutting-edge technology. Agenda: Introduction The power of high-speed printing Know the process The practical side

Entrepreneur Scott Colosimo found early success in China producing parts for his Cleveland-based motorcycle company in the mid-2000s. This is the story of how IP theft issues overwhelmed the business, prompting Colosimo and his team to start over from scratch — and move production back to the United States.

The three smaller end mills shown above have four, five and six flutes. When programming a cutter for an operation that requires more engagement between cutter and workpiece (as in traditional roughing), choose the smaller number of flutes. Where less engagement is appropriate (as in constant-angle roughing, semi-finishing and finishing), choose a higher number. Machines designed for titanium machining can use a larger-diameter end mill like the eight-fluted one on the far right, although this rule about the best number of flutes still applies.

This approach achieves an adequate metal- removal rate with lighter cuts. The lighter cuts, in turn, keep the individual flutes of the cutter in contact with the workpiece for a shorter period of time, so less heat can be absorbed. “And that’s how this strategy wards off the excessive heat buildup that damages cutting edges,” Mr. MacArthur concludes.
