TDSN 235 - Tool & Die Design Transfers
4 Credit: (1 lecture, 3 lab, 0 clinical) 4 Contact Hours: [TDSN 136]
This design course is structured for both tool-and-die apprentice students and tool-and-die journeypersons with several years in the trade who wish to update their skills. Lectures are followed by laboratory sessions that consist of developing sheet metal die components. Emphasis is on application of design ideas and being able to communicate design ideas graphically. Topics include basic tools, dies and punches; blanking force and standard die sets; die components with emphasis on progressive dies; development of a process flowchart; progression of die; development of draw and flange stations, press cushions and air pins, and horizontal cams; and knowledge of tool-and-die standardized components and catalogs.
OFFERED: spring semesters
