Dismayed by the shortage of engineering graduates who had much—if any—exposure to motion control or fluid power in school, Parker Hannifin decided to take matters into its own hands. Over the past decade, the company has donated nearly $1 million to engineering schools to fill that void. "In the past, we could hire a business major with a high mechanical aptitude for a sales position. Today, we need engineers who are trained to solve problems and are technically knowledgeable in what we call the tri-technologies: electrohydraulics, electromechanical technology, and electropneumatics," says Larry Schrader, global motion and control training manager for Parker. To date, Parker has given funds to nine engineering schools to establish programs and laboratories in the tri-technologies. The schools, which include Purdue and the University of Illinois, are selected on the basis of their willingness and ability to make a long-term commitment to the program. To date, Parker estimates that hundreds of students have benefited. So, presumably, has industry.
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
Engineers at the University of San Diego’s Jacobs School of Engineering have designed biobatteries on commercial tattoo paper, with an anode and cathode screen-printed on and modified to harvest energy from lactate in a person’s sweat.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
