A Metal Casting Laboratory Exercise - Collaboration Between the Engineering and Art Department at Texas A&M University Corpus ChristiA metal casting laboratory experiment part of a Manufacturing Processes engineering class is described.Engineering students working in teams design and fabricate expendable patterns according tospecifications, perform lost-foam casting of aluminum material, and analyze the quality and strength ofthe castings obtained. Multiple parts shaped as tensile-testing specimens are cast simultaneously tomaximize output. Students then evaluate the ratio of total weight of the castings over that of the usefulparts, and perform tensile testing of the latter. Prior to testing, through visual inspection and crosssectional area calculation, students also rank the parts according to the anticipated strength. Thelaboratory culminate with writing of a technical report where the entire process is described, and theobserved differences between the anticipated strength and actual strength of the parts are explained.This hands-on experience is offered through a collaboration with the Art Department at Texas A&MUniversity Corpus Christi, which provide the metal casting logistics. Graduate students majoring insculpture who routinely perform casting of their work, provided the support and shared theirexperience with the engineering students. Engineering student opinions of the lab experience, asdetermined through anonymous surveying, are also presented in the paper and ways to improve the labbased on these feedbacks are discussed.
