Peter Zelinski Editor-in-Chief

Peter Zelinski has been a writer and editor for Modern Machine Shop for two decades. One of the aspects of this work that he enjoys the most is visiting machining facilities to learn about the manufacturing technology, systems and strategies they have adopted, and the successes they’ve realized as a result. Pete earned his degree in mechanical engineering from the University of Cincinnati, and he first learned about machining by running and programming machine tools in a metalworking laboratory within GE Aircraft Engines (now GE Aviation). Pete is also the editor-in-chief of Additive Manufacturing magazine.

Metal AM in a Machine Shop? Ask the Marines

A hybrid system combining metal 3D printing with machining gives the Marine Corps perhaps its most effective resource yet for obtaining needed hardware in the field. It also offers an extreme version of the experience a machine shop might have in adding metal AM to its capabilities.


Training Center Leader Says AM Affects Many Competency Areas

Established knowledge and skill areas ranging from engineering design through postprocess testing and inspection and even supply chain management all need to be rethought with additive in mind.

Lightweight Motorcycle Made Through AM to Be Seen at IMTS

Additive manufacturing allowed electric bike’s frame to be optimized for minimal mass and material.


At IMTS, Methods 3D to Place AM in the Midst of Machine Tools

Machining demos will show additive parts postprocessed on CNC machines, and a high-speed 3D printing system will show fully automated production. “This is a manufacturing technology,” says company COO.


EOS in Two IMTS Pavilions with AM Advances

Applications include multi-part production and an automated system for mold tooling. The company’s North American User Day also returns to IMTS.

Additive Manufacturing and CNC Machining: Separate Together? Hear the Recorded Webinar

A maker of CNC machine tools and a maker of AM technology come together to describe integrating additive and subtractive into an efficient process for production.


Integrating Additive Without Inhibiting Machining

Can AM be added to a CNC machine tool while keeping the machine’s cutting capabilities fully intact?

Impressions of Rapid 2016

Software and synergy were two of the noticeable themes of the show. More noticeable still was the emphasis on industrial production.

Hybrid Machine Tools Won’t Need CNC Advances, Siemens Says

Today’s CNC is ready for these machines. Standard control technology is sufficient to oversee additive and subtractive together.


AM System Using TIG Welding and Robot Relies on Flexible Enclosure for Gas Protection

The WAAM system has demonstrated the ability to produce a titanium aircraft part, but titanium in particular requires protection against oxidation.


Arcam CEO Speaks of Promise and Progress in Aerospace and Orthopedic Industries

Growth is expected as both industries transition more production components to AM.
