Design of Grain Cart Mainframe Welding Jig
Notice bibliographique
Résumé
Elmer’s Manufacturing is a rapidly growing company, located just north of Altona, MB, that specializes in the production of agricultural equipment such as grain carts, harrows, ditch cutters, and bale processors. Elmer’s is looking to increase their manufacturing capacity to produce products that are in high demand. The management team at Elmer’s is in the process of physically expanding their facilities while improving the efficiency of their manufacturing processes. Team 18, a group of four mechanical engineering students from the University of Manitoba, has been selected to assist the team at Elmer’s Manufacturing with one of their improvement projects. The project is meant to decrease the assembly time required to tack weld grain cart mainframes together by utilizing a jig system that is user-friendly and effective. The goal of this project is to decrease the six-hour assembly time of a mainframe by 30%. This final design report covers the overall process leading to the final design and outlines content written in the problem definition report and concept definition report. The introduction provides background to the project and an overview of the project definition report, which was used in phase one of the project. The external research section outlines topics that the student design team researched in preparation for the concept development for this project. Concept generation, completed by the team, with assistance from industrial and academic advisors, resulted in a total of 21 conceptual solutions to the project. Through the process of screening and analyzing concepts based on criteria deemed to be important to the success of the project, the team was able to narrow the desirable solutions down to three concepts. The three concepts were further iterated and optimized until only one design was chosen. After much time in discussion amongst the team and with an engineer from Elmer’s Manufacturing, the final design chosen was the upside-down assembly variation. Fixtures and jigs were later made for this design to ensure that all parts were located and clamped efficiently. This design is modular to be able to work with all four grain cart mainframe assemblies. Concerning the final design, CAD models, a bill of materials, drawings, DXF files, a standard operating procedure, and a cost analysis are delivered within this report to be presented to Elmer’s Manufacturing. In order to prove that this design decreases the six-hour assembly time of a mainframe by 30%, testing and further study will need to be done by workers at Elmer’s Manufacturing.

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
