The power of connections Engineers and others working in fluid power understand the importance of connecting with their peers. This is especially true for those younger individuals just entering the field. Fluid power is a technology that many (myself included) admit they “just fell into.” Very few actually enter it intentionally (apart from those involved…

Don’t leave humans out of the Industry 4.0 equation At the recent Integr8 conference in Detroit, a panel of five speakers from Bosch Rexroth discussed how to successfully implement Industry 4.0. Key to connected industry, they all agreed, was ensuring that people are at the center of decision-making. Rodney Rusk, the i4 business leader for…

Pneumatics and automation must go hand-in-hand to survive Although some manufacturers are moving away from pneumatics in their machine designs, the industry can continue to grow if done smartly. That is, seamless integration of automation and pneumatics will rely heavily on the continued adoption of smart technologies, data collection and use, and more compact, efficient…

The reality of women in engineering leadership Last month, I wrote about the need for mentoring to get more young people — young women, in particular — studying engineering and entering the field. There’s a reason for this. Despite strong recruiting efforts, women just aren’t entering the engineering space. According to research by the Society…

Our future lies in engaging the littlest engineers among us My thoughts and face now grace this column in every issue, thanks in part to a surprise promotion by our VP, Editorial Director Paul Heney at the conclusion of our Women in Fluid Power Panel at our Fluid Power Technology Conference. He couldn’t have picked…

Boston Dynamics talks fluid power, 3D printing at IFK More than 650 fluid power manufacturers, users and academics came to Aachen, Germany last month to talk about the future of hydraulics and pneumatics technology at the 11th IFK. Aaron Saunders, VP of Engineering of Boston Dynamics gave a memorable keynote address. Boston Dynamics is the…

At first blush, the industrial robotics market doesn’t appear to be a place for fluid power. Walk through an industrial trade show, and you’ll see a multitude of Delta, SCARA, Cartesian and other types of robots busy demonstrating their skills. And each of them is run by electric drives— certainly not hydraulics or pneumatics. But…

  Will automation make too many jobs irrelevant? At the National Fluid Power Association’s recent Industry and Economic Outlook Conference in suburban Chicago, Kevin Surace of Appvance spoke about the amazing disruptions that technology will play in our lives over the coming decades. The future is both scary and amazing, but we have to prepare…

  Building a better event Although you may be thinking Fall, we’re already thinking Spring, because we’re knee-deep in the midst of planning for our third annual Fluid Power Technology Conference & Expo in Milwaukee. The conference, held at MSOE’s Kern Center, is already set for May 15-16, 2018. One of our takeaways after successfully…

  The value of associations is in participation I’ve been a big proponent of associations over the course of my career covering the world of fluid power. They’ve helped me meet and interact with important industry leaders, network with readers, and understand the critical issues facing manufacturers today. I recently had the chance to catch…

  A cause for optimism? It’s been the heart of trade show season the last few months, with the triennial IFPE, the annual Hannover Messe and Offshore Technology Conference keeping the fluid power manufacturing community—not to mention us in the media—quite busy. It is always great to get out and see the new technology firsthand,…
