Manufacturing in the spotlight at CVTC
March 3, 2014
From leadertelegram.com: “Manufacturing in the spotlight” — A group of high school students stood wide-eyed as a Chippewa Valley Technical College student dropped a metal ball that seemed to defy gravity as it fell through a simple copper tube. It fell slowly through the tube as if moving in molasses, never touching the sides.
The demonstration of electromagnetic forces took place in the Nano Engineering Technology area of CVTC’s Manufacturing Education Center last March at the annual Manufacturing Show, which returns for a third year Thursday.
That simple ball-and-tube trick will have to take a distant back seat to other high-end demonstrations this year. For instance, CVTC now has equipment that uses streams of water under extremely high pressure to cut metal in precise detail, without the harmful effects heat-based metal cutting can leave behind.
Manufacturing Show demonstrations also will include a three-dimensional printer that doesn’t use ink. Instead, it produces, layer after layer, at high speed, a 3-D plastic model of items drawn up with paper and numbers.
“It gives us an ability to replicate a concept or design, showing the working parts,” said CVTC Associate Dean of Manufacturing Jeff Sullivan. “The printers are being used a lot in the medical field.”
New machine tool program equipment that will be on display is capable of speeds up to 12,000 rpm. “The purpose of the high speed is higher accuracy and tighter tolerances,” Sullivan said.
And the purpose of students working on such a machine is to prepare them for the kind of equipment being used in the industry today, important given the prevalence of the machine tool industry in the Eau Claire area.
Welcome to the world of modern manufacturing. People who still picture manufacturing as taking place in dark, dingy places with low-skilled workers doing simple repetitive work will have their minds changed by attending the show, people affiliated with the event said.
“The entire show will present a good overview of manufacturing careers in western Wisconsin,” said Roger Stanford, CVTC vice president of instruction. “We have a great diversity of manufacturing companies in this area, many of them producing products that are getting attention worldwide. Attendees can learn more about these companies at the Manufacturing Show and how CVTC prepares workers for lucrative careers in manufacturing.”
About 20 manufacturing companies will have displays about their role in their industries and in the Chippewa Valley economy. They will use the show to recruit new workers as well.
Joining those companies will be representatives of CVTC’s manufacturing programs: electromechanical technology, industrial mechanic, industrial mechanical technician, machine tooling technics, welding and welding fabrication. Some of the physical science programs, such as nano engineering technology, manufacturing engineering technologist and industrial engineering technician also will be involved.
Students play a vital role in the show. As part of regular course work, they have constructed and programmed robotic equipment that performs such tasks as playing a guitar, making a golf putt or resetting bowling pins.
Area high school students also will be heavily involved in this year’s show. Back again will be the Junkyard Battle, in which high school welding students will compete with their creations made of scrap metal. Last year the contest featured student-made sculptures of their school mascots. This year’s show will feature several more competitions.
Machine tool students will compete in the Amazing Maze event, creating complicated mazes in competition for the best design. Engineering students will use computer-aided design programs to draw up plans for devices. The top design will be reproduced on the 3D printer.
In the electromechanical area, students will create robots that work through a maze without human intervention. The industrial mechanics program is working on a competition involving development of miniature cannons.
“We are reaching out to our K-12 school district partners to develop agreements and programs that expose younger students to manufacturing and prepare high school students for entry into CVTC’s manufacturing programs,” Sullivan said.
The event has been well-attended by the general public since its inception, and area school districts take advantage by using it as an educational experience for students. Some parents bring their children who are starting to think about careers.
The show offers plenty for attendees to do, such as trying out simulators, watching robotic welders, learning what local manufacturers are producing and witnessing student creativity.
