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.

Depending on the amount of material needed to make an insert, ceramic inserts could be anywhere from 1.5 to four times more expensive than inserts made of more commonly used materials, said Martin Dillaman, global manager of engineering and applications at Greenleaf Corp. in Saegertown, Pennsylvania. Dillaman added that solid-ceramic tools probably cost two to four times as much as their counterparts made of more widely used materials. He added, however, that the higher cost of ceramic tools can be justified by savings in cutting time and throughput increases at shops that use them.

SSP’s commitment to adopting the latest machining technology benefits not only the business, but its employees as well.

Wheel formed from abrasive material mixed in a suitable matrix. Takes a variety of shapes but falls into two basic categories: one that cuts on its periphery, as in reciprocating grinding, and one that cuts on its side or face, as in tool and cutter grinding.

Milling cutter held by its shank that cuts on its periphery and, if so configured, on its free end. Takes a variety of shapes (single- and double-end, roughing, ballnose and cup-end) and sizes (stub, medium, long and extra-long). Also comes with differing numbers of flutes.

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

“That material is both abrasive and creates heat, and those are the things that wear out tools the fastest,” he said. So for this application, “people will go from carbide straight to CBN, and the cost difference between those two is astronomical.”

In addition, he noted that users of ceramic inserts in these cases aren’t limited by the form on a grinding wheel. Instead, they can program different cutting profiles to meet different requirements.

Across a range of technical presentations aimed at small and mid-sized job shops, the first-ever Automated Shop Conference (TASC) offered insights into several automated technologies, implementation strategies, shopfloor training tips, and even the untapped power of automated coolant delivery.

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."

Are AMRs the next big trend in job shop automation? System 3R’s IMTS booth will emphasize both its specialty EDM tooling and its automation products, including an autonomous moving robot.

Refined machines at EROWA are handling heavier loads, while its precision workholding enhances stability and rigidity.

Misapplication of these important CNC features will result in wasted time, wasted or duplicated effort and/or wasted material.

The main advantage of ceramic tools is the effectiveness with which they handle the heat generated by the cutting process.

Process that vaporizes conductive materials by controlled application of pulsed electrical current that flows between a workpiece and electrode (tool) in a dielectric fluid. Permits machining shapes to tight accuracies without the internal stresses conventional machining often generates. Useful in diemaking.

Kennametal put considerable work into finding the tooling that would excel in these tests, Mr. Mueller says. The company performed its own testing at its facilities in Germany, Tennessee, and North Carolina using five different machining centers. Chip flow and formation were analyzed using high-speed cameras, and he says a refined tool-grinding processes was developed as a result of this analysis. Ultimately, nearly 300 different tools were produced for use in the project, and 15,000 cubic inches of titanium were machined.

Substance used for grinding, honing, lapping, superfinishing and polishing. Examples include garnet, emery, corundum, silicon carbide, cubic boron nitride and diamond in various grit sizes.

The fact that the tool makes effective use of six flutes proved key. Other cutters in the testing had five flutes, reducing metal removal rate.

Each tool setting technique has merit, and it depends on where you are as a shop and the type of work you do, as cost and efficiency all come into play.

Ceratizit USA announces it has appointed Carlos Garza as its business development leader for the oil and gas industry sector.

“Stainless steel is an area that a lot of people never think of ceramic for,” he said. “It’s got to be hard, though — above, say, 32 to 35 Rockwell — because we’re going so fast and (therefore) cut so hot.” If the steel is below that hardness level, “you will melt it and light it on fire.”

Nesting parts for fabrication, woodworking or soft goods production saves money by optimizing material usage and reducing waste. NestingWorks is a SolidWorks add-in that can be used independently for nesting or in combination with your integrated CAM software to create CNC programs for machining of the nested sheets of parts.

As for the aircraft manufacturer, the evaluation continues. Future tests will evaluate inserted tools. And even the determination related to solid carbide tools will not have an immediate impact, because in the aerospace sector, parts are frequently certified and then locked against further manufacturing process change. But for new part programs developed from this point forward, the manufacturer and its suppliers will have an ever-more-focused range of cutters from which to choose.

Workpiece is held in a chuck, mounted on a face plate or secured between centers and rotated while a cutting tool, normally a single-point tool, is fed into it along its periphery or across its end or face. Takes the form of straight turning (cutting along the periphery of the workpiece); taper turning (creating a taper); step turning (turning different-size diameters on the same work); chamfering (beveling an edge or shoulder); facing (cutting on an end); turning threads (usually external but can be internal); roughing (high-volume metal removal); and finishing (final light cuts). Performed on lathes, turning centers, chucking machines, automatic screw machines and similar machines.

Hardness is a measure of the resistance of a material to surface indentation or abrasion. There is no absolute scale for hardness. In order to express hardness quantitatively, each type of test has its own scale, which defines hardness. Indentation hardness obtained through static methods is measured by Brinell, Rockwell, Vickers and Knoop tests. Hardness without indentation is measured by a dynamic method, known as the Scleroscope test.

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. Now the couple is working to get their startup machine shop off the ground, sourcing new customers and getting the word out about their shop in Clarksville, Indiana. The couple — proud to publicize their "Made in the USA" parts — is leveraging family connections and manufacturing capabilities back in India, but not in the way that some people assume.

“Traditionally, you have to use an electrode to burn material out of a hardened workpiece,” he said. “With our solid-ceramic endmills, (you can) use the endmill to remove the bulk of that material instead of having to create an electrode to remove the full amount of material.”

Automation is no longer a luxury in manufacturing today – it’s a necessity. The Automated Shop Conference (TASC) will connect job shops with experts who offer advice and considerations for this process.

In the tools developed for this application, an already existing carbide grade proved effective, the company’s KCSM15 Beyond grade. The new modifications to this tooling that now exist in the Harvi III line relate to edge geometry, Mr. Mueller says.

Tangential velocity on the surface of the tool or workpiece at the cutting interface. The formula for cutting speed (sfm) is tool diameter 5 0.26 5 spindle speed (rpm). The formula for feed per tooth (fpt) is table feed (ipm)/number of flutes/spindle speed (rpm). The formula for spindle speed (rpm) is cutting speed (sfm) 5 3.82/tool diameter. The formula for table feed (ipm) is feed per tooth (ftp) 5 number of tool flutes 5 spindle speed (rpm).

Dillaman also reported that Greenleaf got good results when it pitted ceramic inserts against PCD in an aluminum-cutting application for a customer. He said the ceramic inserts that were used showed little wear and held up as well as their PCD counterparts. The biggest downside for ceramic inserts was the accumulation of some built-up edge that had to be removed.

In this episode of Made in the USA, several executives and senior staff at Hardinge give their first-person account of how they formulated the plan to shift the manufacturing of its milling and turning product lines from its Taiwan plant to its plant in Elmira, New York, the major challenges they encountered and the rewards that made it worth the effort.

1. Permanently damaging a metal by heating to cause either incipient melting or intergranular oxidation. 2. In grinding, getting the workpiece hot enough to cause discoloration or to change the microstructure by tempering or hardening.

Machining of a flat, angled or contoured surface by passing a workpiece beneath a grinding wheel in a plane parallel to the grinding wheel spindle. See grinding.

When it comes to ceramic cutting tools, don’t believe the old saying, “What you don’t know can’t hurt you.” A lack of knowledge about ceramic cutters can put a big hurt on shop productivity. What’s more, even shops that are somewhat informed about ceramic cutting tools often aren’t getting the most out of the tools because they are unaware of lesser-known applications that are a good fit for ceramic machining, let alone recent developments that make the ceramic option more attractive than ever.

Thoughtful considerations will set you on a shortened path to the most optimized solution once cutter meets metal.

Legacy Precision Molds takes us on a tour of their moldbuilding facility. They've recently implemented two automated 5-axis cells for metal and graphite machining that run lights out during nights and weekends.

Cast iron having a graphite shape intermediate between the flake form typical of gray cast iron and the spherical form of fully spherulitic ductile cast iron. Also known as CG iron, CGI or vermicular iron, it is produced in a manner similar to that of ductile cast iron but using a technique that inhibits the formation of fully spherulitic graphite nodules.

“If somebody is cutting heat-resistant alloy at 125 sfm, and you bring in this new product that can do 1,600 sfm, it’s kind of like taking somebody from a horse to a rocket ship,” he said. So sometimes “the (reaction) is, ‘There’s no way I’m doing that.’”

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

Cutting tool maker Kennametal reports it was the winner of a recent competition by a “major U.S.-based aircraft manufacturer” (the company doesn’t wish to be named publicly) aimed at standardizing its solid carbide end mills. According to Kennametal’s manager of solid end milling tools Thilo Mueller, the problem the aircraft manufacturer still faces is this: An expanding number of active machined parts has led to an ever-expanding universe of cutting tools that the manufacturer and its suppliers are using. Historically, manufacturing engineering personnel have had too much freedom—more freedom than necessary—in specifying the tooling for a given part. Limiting the range of choice as much as possible to a standard menu of tools would control costs for the aircraft maker by controlling the scope of tool management. It would also help avoid unexpected delays, because those standard tool choices would become standard items that the tool suppliers would be more likely to have in stock.

Structured light scanning is used to create a digital twin of a manufactured part, but we must understand the measurement reproducibility to best use the data.

Tool-holder-spindle-machine combinations each have a unique dynamic response in the same way that each person has a unique fingerprint, which can be revealed using modal testing.

Understanding all the things that contribute to a machine’s full potential accuracy will inform what to prioritize when fine-tuning the machine.

He pointed out, however, that NTK makes ceramic tools that can cut CGI for 10 times less than the cost of carbide tools. But few in the industry know this.

Get sensible, real-world automation solutions during this half-day workshop co-located with IMTS 2024.

“The big thing with ceramic is it conducts heat better than anything else,” said Steven Howard, marketing and engineering manager at NTK Cutting Tools USA in Wixom, Michigan.

JD Machine, 2024’s Top Shops Honoree in Human Resources, embodies its “Education for Life” core value with a robust apprenticeship program and significant continuous improvement efforts.

Another invention of late that may interest shops that haven’t tried ceramic tools in a long time is a patented material called Bidemics. Howard describes Bidemics as an advanced ceramic designed to conduct more heat away from the cutting edge.

During the final round of testing, Kennametal used a Haimer Safe-Lock shrink-fit holder and was able to run all of its tools in the exceeds category. With the traditional milling approach, less than 0.001 inch of tool wear was observed after 1 hour, with a surface finish of 23 μin Ra. Within the high velocity testing, tool wear measured less than 0.0014 inch and surface roughness was better than 27.5 μin Ra. Perhaps most significantly, the Harvi tools permitted a 20-percent higher metal removal rate than others because the design enables effective use of six flutes where other end mills were limited to five.

Howard also noted that ceramic tools are a good choice for cutting compacted graphite iron, which he described as a fairly new type of cast iron that’s very dense and strong. Today, he said, CGI is used to make many diesel engines because it allows manufacturers to use a smaller engine block that can take more compression.

Information about these applications usually falls into the category of what people in the machining industry don’t know about ceramic cutting tools. Equally frustrating for the firms that sell these tools, however, is what many people think they know based on outdated information.

A relatively new entry in the ceramic tool market from Greenleaf is its Xsytin-360 line of solid-ceramic endmills. Launched last year, Xsytin-360 endmills come in standard diameters down to 3/8", so they can cut much smaller features than indexable tooling.

ANCA CNC Machines is celebrating its 50th anniversary as a global producer of CNC tool and cutter grinders.

On the downside, Howard pointed out that the hardness of ceramic materials makes them brittle, so those who make tools out of ceramics can’t put very sharp edges on them. As a result, he said, ceramic tools don’t cut as efficiently as carbide tools.

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

Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.

Are AMRs the next big trend in job shop automation? System 3R’s IMTS booth will emphasize both its specialty EDM tooling and its automation products, including an autonomous moving robot.

The 5-Axis Live technology event will highlight new machining strategies for optimizing the production of complex medical, aerospace and mold/die parts.

But which tools to choose? Answering that question led to the competition. Various cutting tool suppliers submitted tooling for machining trials that were conducted at the University of Sheffield’s Advanced Manufacturing Research Centre (AMRC) in the United Kingdom. To pursue better results within the test parameters, Kennametal modified an existing tool design—its “Harvi” end mill design featuring unequally spaced flutes to break up chatter, eccentric relief to extend tool life, and a tapered core for stability during heavy cutting. That modified tool is now available to the aircraft manufacturer and to others as the tool maker’s new “Harvi III Aerospace” line.

FANUC’s IMTS 2024 booth includes real-time demonstrations that show the abilities of its equipment, including robots, controllers and machine tools.

In recent years, Bidemics has become popular with makers of larger aerospace engines, Howard said. But he added that some shops find the performance boost offered by the material a bit unsettling.

From quadruped robot dogs, to an in-booth putting green where you can test out a new golf putter, to a 3D-printed car and more, attendees enjoyed cutting-edge technology and innovations all week long. Take a look to see what (or who!) you might have missed this week!

Dillaman said these endmills are made from the company’s Xsytin-1 material, which features a “whisker,” or reinforcing material, that’s grown internally via processing rather than laid in. This makes the ceramic material much harder to break apart, he said. He added that Xsytin-1 has shown itself to be capable of handling challenging roughing applications and turning interruptions.

Strict guidelines governed what kinds of tooling could be used. Initially, the solid carbide end mills in all these cases had to be 1.25 inch in diameter, with a flute length of 4 inches, corner radii of 0.09 inch and a flute count of either five or six. Further testing then evaluated different combinations of tool diameter, length and corner radius (up to the full radius of a ballnose tool), Mr. Mueller says. Tools were required to achieve axial depth of cut of 2 inches while extending from the holder exactly 4.5 inches. And in all of this (sorry, metric system), only imperial units were allowed. Within these constraints, the tooling supplier was free to put forward its best choice of tool coating, carbide substrate and cutting geometry.

Heidenhain and Acu-Rite Solutions are offering several hands-on experiences at their booth this year, as well as internal components that reduce energy use.

The amount of heat produced during the cutting process is a function of the cutting speed and the material being machined. So the ability of ceramics to conduct heat away from the cutting edge means that ceramic tools can run much faster than those made of carbide, CBN or PCD when cutting most materials, Howard said. He noted that while carbide tools cut heat-resistant alloys at 125 sfm, for example, ceramic tools can cut them at anywhere from 800 to 1,500 sfm.

The latest episode “Made in the USA” podcast explores a company that uses collaborative robots, one of the key tools helping US machine shops and other manufacturers compete with lower cost countries by automating production.

Even if shops aren’t put off by the higher cost of ceramic tools, shops may be unable to make proper use of the tools because their equipment can’t match the speeds for which ceramic tools have the capacity. Or shops actually may be afraid to reach those speeds.

User-friendly inspection software for CNC machining centers is shown monitoring measurements between and after machining while performing SPC based on recorded measurement values.

Standards for surface finishes and profiles are not static; they change as technology changes or new processes come along that need to be considered.

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

When people tell Howard that they tried ceramic tools for a particular application and it didn’t work, he asks when they tried ceramics. Sometimes, it turns out that the failed ceramics experiment wasn’t even in this century. So he tells these people, “Well, we’ve invented a few things in the last 20-some years.”

A ceramic endmill removes material much more quickly than an electrode, he said, and use of an endmill should slash the number of electrodes needed for the overall process, as well as the time spent creating them.

In addition, he noted that ceramic tools are more expensive than their carbide counterparts. When it comes to tools with inserts, he said this is because ceramic inserts require a good deal of grinding while carbide inserts are easily mass-produced.

Legacy Precision Molds takes us on a tour of their moldbuilding facility. They've recently implemented two automated 5-axis cells for metal and graphite machining that run lights out during nights and weekends.

In this webinar, CloudNC Co-Founder Theo Saville reveals how U.S. machine shops are using cutting-edge AI today to accelerate their CNC machining, helping them become more efficient and save over 1,000 production hours per year. Theo will demonstrate CAM Assist, an AI solution that automates CAM programming within existing CAD/CAM platforms — and even provides working physics-based cutting parameters for your existing toolsets. Attendees will learn how the technology has developed, its current capabilities and applications, and how it is expected to progress in the near future. Agenda: How U.S. machine shops are using AI tools to automate their CAM programming and increase their productivity and efficiency How AI tools can help fill the CAM programming skills crisis What tasks AI can be successfully applied to today and what the future holds How AI can fit into machinists' workflows today without specialist training Advanced applications, such as setting cutting parameters and soft jaw fixtures with AI

Tool-holder-spindle-machine combinations each have a unique dynamic response in the same way that each person has a unique fingerprint, which can be revealed using modal testing.

When cutting with common tool materials, such as carbide, CBN and PCD, heat is not conducted away from the cutting edge, which eventually breaks down as a result, Howard explained. By contrast, he said, ceramics do a good job of transferring heat away from the cutting edge, thereby extending its life and the life of the tool as a whole.

Formnext Chicago is an industrial additive manufacturing expo taking place April 8-10, 2025 at McCormick Place in Chicago, Illinois. Formnext Chicago is the second in a series of Formnext events in the U.S. being produced by Mesago Messe Frankfurt, AMT – The Association For Manufacturing Technology, and Gardner Business Media (our publisher).

The AMRC testing focused on forged titanium 6Al4V. Three sets of cutting parameters apiece addressed both traditional-milling and high-velocity approaches for the aircraft maker. In each case, the three sets of parameters were designated as “current,” “meets” and “exceeds” expectations. In the traditional rounds, a 0.1-inch radial depth of cut was specified, with cutting speeds ranging from 150, to 200, to 250 sfm for current, meets and exceeds categories, respectively. In the high-velocity testing, depth of cut dropped to 0.02 inch while speeds increased to 400, 450 and 500 sfm, respectively.

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.

Because they do a better job of transferring heat away from the cutting edge, Bidemics inserts can run even faster than typical ceramic cutters — close to 1,600 sfm, Howard said. He added that efficient heat transfer also lengthens the life of cutting edges.

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

Ceramics “run so much faster” than carbide, Howard said. “And with that comes a lot of fear. People say, ‘Wow, I can’t control this thing because I don’t have enough knowledge or skill.’”

“You may still have to do some finish work with an electrode, but the amount of electrodes consumed should be much reduced,” he said.

In general, Howard believes there’s a fairly widespread lack of knowledge about ceramic cutting tools in the machining industry. So he had no trouble identifying some lesser-known applications for these tools. One is cutting hardened stainless steel.

Thoughtful considerations will set you on a shortened path to the most optimized solution once cutter meets metal.
