Learning Objectives

  • Learn applications of CNC, robotic welding and metal-forming processes at the Freedman Seating Co.
  • See examples of manufacturing training at Jane Addams Resource Corp. (JARC) in Chicago.
  • Learn the steps that lead from manual processes, to digitalization and finally to full-blown digital transformation.

Automated manufacturing insights

  • Applications of CNC, robotic welding and metal-forming processes were described during a Freedman Seating Co. tour.
  • Examples of manufacturing training were shown at Jane Addams Resource Corp. (JARC) in Chicago, co-located with Freedman Seating Co.

Freedman Seating Co. offered tours in association with the Jane Addams Resource Corp. (JARC) Women in Manufacturing event, March 29.

While automated welding is part of the manufacturing process, manual welding also is needed. Welding, safety and CNC are among training certifications JARC offers in its onsite training facility at Freedman Seating Co.

Karen Arroyave, M.E., a Freedman Seating manufacturing engineer, gave the tour. She is working on a master’s degree to further advance manufacturing efficiency.

The 130-year-old company employs about 650, including 30 in a plant in Indiana, and was in the process of hiring 50 more people as of the tour. Freedman Seating began manufacturing buggy seats and now makes seats for campers, buses, trains and ferries. Processes combine manual and automated techniques and robots, using fabric, padding, sheet metal to make tubing and bases to integrate with other materials to construct a diverse range of vehicle seats.

Computer-numerical control, automated cutting, forming, welding

In the cutting department, many layers of fabric are cut to fit using CNC automated cutting machines. Sewing uses automated and manual machines.

Laser-welding tube fabrication cuts and welds tubing used for seats. Tube bending and cutting are automated, along with sheet metal cutting, bending and fabrication for seat bases.

Welding, CNC, 3D printing and other skills for manufacturing

The JARC manufacturing training portion of the tour included four welding booths, two CNC machines and a 3D printer that help teach manufacturing skills to those in need of higher-paying, more fulfilling careers than what they had. JARC also provides a wide range of manufacturing-related certifications, life skills and career training and placement at no cost to participants.
