Emily Probst is the associate editor for Modern Machine Shop. She joined the staff in the summer of 2006 as the editorial intern editing product releases for the International Manufacturing Technology Show (IMTS). Hired full-time in 2007 after graduating with a B.S.J. from Ohio University, she edited product releases and columns until 2012, when she moved to her current role of writing and editing case studies for both print and online media channels. In this role, she has been fortunate enough to travel the world as well as visit some interesting shops and trade shows in the United States. She also administers Modern’s blog as well as its Facebook, Twitter and YouTube accounts.
It makes smart business sense to compare your company to those similar in the metalworking community. One way to do this is to participate in the annual Metalworking Operational Trends Survey from LoSasso Integrated Marketing. In return, you will be entered for a chance to win a $500 Amazon gift card, and if you provide your email address, you can choose to receive the Executive Summary once it is finalized. The Executive Summary includes snapshots on the overall health of the metalworking industry, strong and weak performers, and purchase drivers.
The cover story for our October 2015 issue tells the story of East Branch Engineering, a company that uses live-tool turning centers to complete complex parts in one setup. However, it also leverages a flexible and reconfigurable “mini-cell” strategy to enable a single operator to tend two machines at once, essentially gaining “free” machining time by overlapping operations.

When everything is connected to everything else, manufacturing will have a very different face.
The cover story for our September 2015 issue describes seven things you should know about the Internet of Things (IoT) and Industry 4.0. The IoT is the intelligent connectivity of smart devices by which objects can sense one another and communicate, thus changing how, where, and by whom decisions about our physical world are made. Manufacturing companies are currently implementing this “intelligent connectivity of smart devices” in their factories and on the shop floor. To distinguish these applications of the IoT from those among consumers and other realms, the term Industrial Internet of Things is often used. Read more here.

More than 8,900 people visited DMG MORI's newly remodeled Iga Solution Center
during "Innovation Days" in Japan.
During DMG MORI's “Innovation Days” event July 22-25 in Japan, the company showcased 58 machine tools in its newly renovated Iga Global Solution Center, which boasts 3,500 m2 (37,674 ft.2) of floor space. I, along with other members of the international press, got the chance to visit the spacious new addition, which also houses "Excellence Centers" for automotive, aerospace, die and mold, and medical—four industries in which the company expects continuous growth. The DMG MORI Porsche car is also on display.
During the event, Dr. Thorsten Schmidt, deputy chairman of the executive board, commented on the high stability of machine tool consumption this year. He says that machine tool consumption in the United States is up 6.9 percent, with Japan seeing an 8.1 percent increase, and a worldwide consumption increase of 3.3 percent. Dr. Masahiko Mori, president of DMG MORI, outlined the company’s product offering plans for the future. By 2020, he says DMG MORI wants to reduce its product models from 300 to 150, and provide a wider range of solutions with extensive applications. The company’s goal is to achieve the capacity to produce 18,000 machines a year.
Dr. Schmidt and Dr. Mori spoke to the international press.
Seven machine tools were introduced during the event, one of which was the Lasertec 4300 3D. Perhaps the most fascinating machine for me to see in person, the Lasertec integrates additive manufacturing into a turning/milling machine. The machine uses a directed energy deposition process by means of a powder nozzle, which is said to be 20 times faster in deposition than a powder bed. And as many as five deposition heads can be automatically parked in a secure docking station while turn/mill operations are being performed. The deposition heads can be prepared for ID deposition, OD deposition, large diameters of deposition, or small, heat-treating, surface-hardening, or welding.
According to Rory Dudas of DMG MORI, “Additive is where the future is going.” The fact that the technology can be used to produce complex parts with exotic materials—and it can be used in combination with traditional subtractive machining methods on the same platform means the technology is no longer restricted to the production of prototypes and small parts. Prior solutions were restricted to the build of a single alloy, while the new method enables the machine to use multiple materials—via laminations or gradual transitions from one alloy to another.
According to Dr. Mori, the company is currently selling one additive machine per month, but his goal is to raise that number to five or six.
Other machines that made their world premieres at the event include:
The NLX 300 | 300. This high-rigidity, high-precision CNC lathe features 3,000 mm between centers. It is well-suited for machining workpieces ranging to 3,123 mm long and 430 mm in diameter.
The A-18S (DMG MORI Wasino). This high-precision, compact, multi-processing turning center is equipped with a Y-axis turret and milling functions. It features 18 tool stations—the largest number in its class.
The G-07 (DMG MORI Wasino). The super-high-precision lathe reduces cycle times due to its gantry-type tool post. The gang-type lathe is said to achieve high accuracy in finishing, hard turning and high added-value machining.
The ecoMill 600 V, ecoMill 800 V and ecoMill 1100 V. The newly designed ecoMill V series of vertical machining centers features 6 micron accuracy (without direct scales) due to direct coupling in the X and Y axes. The series does not include a belt drive, which eliminates backlash. To increase productivity, the machines feature a 12,000-rpm spindle speed, 119 Nm of torque and 560 mm of stroke in the Y axis.

“It’s like shuffling a deck of cards every day,” says Paul Hogoboom about the challenge of managing ever-shifting job priorities at P&J Machining. The shop has a long history of light-out machining on flexible machining systems and palletized cells, yet its newest system, which consists of two four-axis Matsurra HMCs with a Fastems pallet storage and retrieval system, represents what Mr. Hogoboom considers the most important advance in this sector of lights-out aerospace machining, namely, the control software’s capability to automatically reschedule job priorities on the fly based on shifting demands in production from customers.
