This project addresses a pedagogical problem related to dimensioning and tolerancing of components and an innovative approach to solve that problem in a Mechanical Engineering freshman level Computer Aided Design and Visualization class. In this class, students learn how to dimension and tolerance a drawing for a part using a set of rules and standards but well dimensioned drawings require that a designer is aware of how the part will be created as well. Our students are asked to be good at dimensioning but they lack the context of how to apply dimensions. This project addresses the lack of experiences that makes it very challenging for our students to construct the knowledge and make this skill be recalled throughout their career. This project allows us to address the problems through a virtual experience. This work provides Mechanical Engineering freshman level students a real life experience of dimensioning and tolerancing in the context of machining. With machining videos that developed in this project, using proper dimensioning and tolerancing technique, students are now able to correlate the importance and significance of proper and practical dimensioning and tolerancing methods with machining on their engineering drawings. Initial assessment was done in the Spring 2019 semester and initial data found a strong correlation of the theory of dimensioning and tolerancing with actual machining in a meaningful way. Preliminary assessment concludes that these machining videos will have a positive lasting impact on how freshman level Mechanical Engineering students think in terms of providing information on their Engineering drawings.
