Exploration of a Student Project in a Materials Processing Course Somnath Chattopadhyay Georgia Southern University ABSTRACTAs a part of the laboratory module for the junior level course in Materials Processing, a projecthas been introduced that the students work three hours every week for one semester. Thestudents are each expected to fabricate a hacksaw from the drawings and work under minimalsupervision. The project is designed in such a way that the laboratory (shop) work followsclosely the lecture classes. The unit on casting is followed by the fabrication of the handle forthe hacksaw which is formed out of cast aluminum. The unit on rolling and bending is followedby the bending of the steel bar to produce the frame of the hacksaw; the unit on sheet metalprocessing is followed by a part of the hacksaw that involves cutting and bending sheet metal;and the general topics of machining is followed by the production of the tensioner whichinvolves turning, facing and turning on a lathe, and a finishing operation by milling. There arealso applications of a number of joining processes like welding and brazing. The students areexpected to maintain strict tolerances for every component of the hacksaw and are evaluated onthe quality of manufacturing surfaces and also on the accuracy of dimensions as specified in thedrawing. As an additional feature, the modules of material and process selection in the computerprogram CES EduPak were employed to justify the choice of the materials of variouscomponents of the hacksaw, and the associated manufacturing process. .
