As discussed in the current issue of Cutting Tool Engineering magazine in the feature article “Specialization on tap,” material-specific taps continue to evolve. Sources anticipate increasing specialization of the materials used for taps across industries.

Despite my sore feet and the cold, overpriced sandwiches, I love the International Manufacturing Technology Show. The whine of the spindles, the smell of the coolant, the machine gun sound of the chips hitting the glass—these might not be the memories the exhibitors want me to carry home, but they stick with me the longest.

Remember that before there was high-tech there was low-tech. And there still is low-tech! For example, boring and cutting a keyway in a tapered bushing is one of the most often performed tasks a maintenance machinist will perform.

Although the title of a book I received a digital review copy of is “Basic Benchwork for Home Machinists,” it contains information that even metalworking professionals might implement on the shop floor or at least enjoy reading.

When mass finishing—finishing many parts simultaneously—in a vibratory finishing system, the tendency is to use ceramic or plastic preformed cutting media, said Steven Schneider, technical sales manager at surface finishing company Kramer Industries Inc., Piscataway, N.J. Ceramic tumbling media are made with abrasive filler, much like a grinding wheel. For plastic tumbling media, plastic is mixed with abrasive filler and cast to shape. Ceramic media use aluminum oxide as filler, and plastic media use quartz or silica for cleaner results.

In connection with the article I’m writing about metalworking fluid filtration equipment for our March issue, I spoke with Irvin Kaage, president of Transor Filter USA, Elk Grove Village, Ill. The company provides the One Micron Filtration system, which removes particles larger than 1µm from oil, primarily for grinding.

The week after CemeCon Inc. held a ribbon-cutting Jan. 17 to officially open its new 15,000-sq.-ft. headquarters and CVD diamond coating facility, I spoke with Gary Lake, company president, to discuss the expansion and developments in cutting tool coating technology. The opening marks the fourth expansion of production capabilities since the company, which is a subsidiary of Wuerselen, Germany-based CemeCon AG, was founded in 1998 and the third increase in capacity for the CVD diamond process since 2014.

Customers of Cobra Carbide asked the company for made-in-America cutting tools and the West Coast manufacturer of drills, endmills, reamers and burs met their request. Until late 2016, Cobra sold tools in the U.S. that were produced either at its Riverside, Calif., facility or a plant it owned in India, which the company recently sold. It now produces all its tools in Riverside. “As more and more customers asked for made-in-the-U.S. product, we changed accordingly,” said Cobra Carbide’s CEO, Rakesh Aghi.

Seventy years ago when the Society of Carbide Engineers launched the trade magazine that eventually became Cutting Tool Engineering as its official publication, the articles primarily covered carbide cutting tools. After all, the association advertised that those who were engaged in studying, using, supervising the use of or furthering the use of carbides were eligible for membership.

While looking through back issues of Carbide Engineering from the late 1950s, I came across an article about HSS cutting tools that reminded me of an article we published in this year’s August issue of Cutting Tool Engineering. (Editor’s note: Carbide Engineering combined with Cutting Tool Engineering starting with the January 1961 issue and dropped Carbide Engineering starting in April of that year. The publication began in 1948 as a small pamphlet called Carbide Tips, but I’m not aware of any existing copies of any issues.)

In connection with my article about flexible manufacturing systems for the February issue, I visited Camcraft Inc., which has a Makino Machining Complex (MMC2) automated pallet-handling system. Four Makino 4-axis a51nx horizontal machining centers are integrated into the system.

Although the book doesn’t cover machining parts, “Blowout” by Rachel Maddow, host of “The Rachel Maddow Show” on MSNBC, does examine an industry that’s a major consumer of precision machined parts—oil and gas.

Since its founding in 2008, 421 graduates of the nonprofit school Workshops for Warriors, San Diego, have earned 2,500 nationally recognized certifications from the National Institute for Metalworking Skills Inc., the American Welding Society and more. Even more noteworthy is the fact that the educational institution exists to train military veterans for metalworking careers. Manufacturers have lined up to support that mission, with more than 70 corporations each donating $10,000 or more in cash, equipment or materials in 2016 and the first 7 months of 2017 alone. Workshops for Warriors must raise $2.5 million annually just to maintain current operations.

In manufacturing, the nature of the work as well as the nature of the workers are changing: What’s a prospective employer to do? Some pre-Manufacturing Day discussion.

Every day, it happens. Someone from Houston calls, or maybe San Francisco, peddling precision-machined parts from China. Then there are the emails from people with fake names—like Lily, Annie and Susan—overflowing my inbox with offers of low part costs and excellent service. Please, China, I don’t want to buy machined parts from you. No metal stampings. No plastic injection molds or 3D-printed prototypes. And at the risk of offending those who do, you shouldn’t either.

After helping customers to remove tramp oil from coolant for more than 40 years, Jim Petrucci, vice president of Oil Skimmers Inc., has yet to hear from anyone that doesn’t have at least some tramp oil present in an individual machine sump or large holding tank. When enough tramp oil seeps into coolant on a steady basis to justify the acquisition of oil-removal equipment, which is common, the Cleveland-based company offers oil skimmers to remove surface oil.

I received an email from a reader letting me know that he disagreed with my recent article on tapping versus thread milling. In it, I stated, “There’s little chance of successfully thread milling metals much above 45 HRC. And if you’re going to try to tap them, be prepared to duck the flying shrapnel when the tap explodes!” We all make mistakes. So when Tom Fares, president of TNT Custom Equipment in Stow, Ohio, called me out on that section of the article, saying that he routinely taps holes in 45 HRC steel alloy and thread mills into “the low 60s,” I listened to what he had to say.

Sept. 25 marked 39 years to the day since I first stood in front of a Hardinge hand screw, scratching my head over the knobs and handles and wondering what I’d gotten myself into. To say that machine tools have improved since then is like saying this year’s computers are only slightly more powerful than those of a decade ago or that salted caramel ice cream is marginally more flavorful than vanilla. Today’s machine tools rock.

New research by the Copper Development Association Inc., McLean, Virginia, shows that U.S. machine shops may be underutilizing the machinability of brass by as much as 85 percent in part-processing operations. The study says manufacturers can and should be machining the material at significantly higher speeds and feeds—often five to 20 times faster—to increase productivity and profitability.

When parts manufacturers enter the world of Industry 4.0, in which their operations are data driven, they will need production control software, such as a program for enterprise resource planning or materials requirement planning. In his new book “How to Implement a Manufacturing System,” Martin Bailey covers the best practices and pitfalls when implementing an MRP/ERP system.
