Software Development for Team Projects in Manufacturing
A software package has been developed to introduce students to the integration of design criteria, material properties, mechanical properties and product cost. The software has been used in the two credit manufacturing processes course for four years and modifications have been made based upon the responses and comments of the students on the assessment questionnaires they completed. The course is required by all mechanical engineering and industrial engineering programs and is scheduled at the junior level. The overview of the typical project, results of the student questionnaires, project changes and software changes are presented.
The basic manufacturing processes course attempts to integrate multiple design criteria, mechanical properties, material properties and manufacturing costs for a specific product. Students need interdisciplinary team projects as part of the ABET requirements and this course is one of only a few that has students from multiple engineering disciplines. The project design criteria are the load requirements and deflection limit for a simple beam structure. The manufacturing processes for the beam such as rolling and extrusion are presented in the discussions in the lectures on bulk deformation processes. The students have had the formulas for the centroid and moment of inertia in their statics and strength of materials courses for the various cross-sectional shapes such as square, rectangle, circular, triangular, I-beam and hollow box. The students must find the moment and inertia equations for an additional shape and have the model evaluate those shapes or create their own program to give the results. The additional shapes typically selected by the students are the hollow circle, T-section, C-channel or U- channel. Previous papers have been prepared on the program and this is an extension of the previous works1-5.
The loading types available in the model are single point center load, single point end load and uniform load. The types of end supports for the beam are simply supported ends, fixed ends, and cantilever support (single fixed end). The program contains 12 materials in the data base and two materials are added to the data base during the model demonstration session. The model is e-mailed to all students in the course for their use. The students must select at least one additional material, obtain the material property, mechanical property and cost data required for the model.
The various reports were required so the students would do work throughout the 10 weeks rather than only at the last two weeks. The first three reports were 10 points each and the
