The pace of technology change in manufacturing over the past four years increased in ways that were difficult to comprehend in real time. These years were marked by uncertainty amid a global pandemic and the cancelation of IMTS, the International Manufacturing Technology Show in 2020.

IMTS 2022, therefore, offered a unique perspective on how shop floor technologies have evolved over the last four years. But the biggest takeaways from this year’s show were not necessarily the new technologies on display (which were plentiful), but the ways in which metalworking OEMs are integrating existing technologies for increased automation.

91ÊÓƵÍøÕ¾ÎÛ’s editorial team fanned out and hit all four halls of McCormick Place to learn more. What follows is a curated, photographic look back at what our editors experienced at this year’s show.

Automation Aplenty

Automation pushed into new territories this year, including automated in-process part inspection, automated data solutions for quality control, and fully integrated and automated production environments.

Integrated Software Shows Its Potential

Several software providers promoted integrated software environments combining features from multiple programs. Marposs’ Maindo software, for example, collects information from machine monitoring and inspection systems, organizing the data on a unified dashboard. Users can take advantage of predictive capabilities to avoid crashes and can cross-correlate measurements and variables such as diameter and temperature to track the causes behind non-conformance.

Siemens’ integrated software portfolio takes a different approach, incorporating CAD/CAM, simulation, inspection and more within a single, cohesive environment — no file conversions necessary.

EVs and Sustainability Drive Innovation

Environmental and sustainability issues can be politically fraught topics in the U.S. Which is why is was fascinating to learn that, for many of the OEMs at IMTS, sustainability is not seen as a political issue at all, but instead is viewed as a movement that is driving advances in precision machining and energy efficiency.

For example, Mitsui Seiki was showcasing its new PJ 812, a three-axis CNC vertical jig mill designed for high-precision contour machining and boring applications. How does this relate to sustainability? Consider plastic bottle manufacturers. Mold-and-die shops serving this industry must accomodate customers demanding thinner and thinner bottles to save on material costs. Meeting this demand requires extremely tight tolerances for the molds, which, in turn, requires high-precision boring machines.

Sustainability issues were directly at the heart of Heidenhain’s LC xx6 series of linear encoders. This new encoder model reads through dust and water, eliminating the need for continuous cleaning via air hoses. Removing air hoses makes operation far less expensive, while also using 99% less CO2. 

Electric vehicle production has also required redesigned equipment across many stages of manufacturing, from machining to inspection. That isn’t to say that this equipment will not prove useful for other tight-tolerance industries, however. For example, Marposs introduced its OptoCloud laser-triangulation point cloud system for inspecting EV engine stators, but noted that the no-contact approach is also useful for aerospace and medical applications.

Evergreen Classics Retain their Place

In addition to advanced technologies, many classics still attracted attention.

A Great Start for the Next Generation

The next generation of manufacturers is key to the continued success of the industry. At the Smartforce Student Summit, high school and college students engaged with cutting-edge manufacturing technologies such as additive manufacturing, automation, digital twins and virtual reality. Students in robotics clubs from schools across the country demonstrated their own creations, giving visitors an idea of the upcoming generation’s capabilities.

Even beyond the Student Summit, many companies offered machines and connectivity devices designed to train new and inexperienced workers. These devices include the Hexagon Machine Trainer, which uses the same interface as a CMM or five-axis machine to provide students and new hires with the chance to practice programming these machines. Heidenhain is also positioning its Bluetooth-powered DROpwr as a tool for wirelessly connecting multiple devices to an encoder interface box.

A Final Takeaway

Like at every IMTS, companies working in aerospace, automotive, medical and more found an overwhelming array of technologies, top-tier guidance and business opportunities. From students seeing their first machine tool spindle to experienced shop owners looking for opportunities to increase automation, the show had something to offer for everyone. But after a four-year absence amid challenging times, IMTS 2022 was, more than anything, a needed reminder that manufacturing touches every aspect of our lives.
