Mechanical Engineering students at Milwaukee School of Engineering (MSOE) study manufacturing processes in the junior year. Part of their study in this course is a project to create an original casting. This project encompasses several steps. First is to design the part and the associated mold system (gates & risers) for sand-casting the part. Next, students analyze performance of their mold layout through the use of SolidCast casting simulation software and make improvements to the initial mold layout. A final version of the casting design is submitted to the MSOE rapid prototyping center for fabrication of the casting patterns. The last step is to make an aluminum sand-cast part, in a small-scale foundry in MSOE’s labs. The project emphasizes the basic premise of the course; a manufactured part must be designed within the limitations and capabilities of the manufacturing process.
Successful completion of the project covers several key course outcomes, including: 1) understand the steps involved in basic green-sand casting process along with its capabilities and limitations, 2) apply this knowledge to design a component and mold layout, 3) understand the characteristics of a good versus poor mold layout, 4) apply modern computing methods as a means to do design of an effective mold for sand casting. With the successful implementation of SolidCast™ and rapid prototyping methods into this project, students learn course outcomes at a much higher level. In the past, the lab was an informative exercise where students made sand cast parts. Now it is a true engineering design experience for the students. They are able to approach mold design as a fluids problem, a heat transfer problem, and a manufacturing quality and cost problem.
