Group 16 - DeWalt 4 1/2 in Angle Grinder
In this project our group will dissect a DeWalt 4 1/2" Angle Grinder in order to analyze its components and gain an in-depth understanding of the design factors and how they influenced the final design. While the angle grinder may only be capable of spinning its attachments at high speeds, the great diversity of tasks and functions provided by those attachments means the grinder had to be designed to function under a variety of orientations, forces, and resistances. By analyzing each component of this product we will determine what factors and considerations went into designing a product that would hold up in these many different scenarios.
In Gate 1 our group formed a plan for dissecting the product, assigned roles and responsibilities to each group member, and came up with a general idea of what we expected to find when dissecting our product.
In Gate 2 our group assessed how we were performing and what issues needed to be fixed within our current group structure. We then dissected our product and formed step by step instructions for this dissection process, along with an analysis of why the subsystems were arranged the way they were.
In Gate 3 our group did an analysis of the manufacturing methods of all parts, along with an in depth analysis of several of the key components of our system. We also considered how engineering analysis would be used in the design of our component's motor. Lastly, our group considered how our changes to group structure have worked and what other issues still need to be addressed.
In Gate 4 our group reassembled our product and created step-by-step instructions for putting the product back together. We also considered how the methods we used for reassembly compared to the disassembly, as well as the original assembly methods that would have been used in a factory. Lastly, our group assessed the effectiveness of our solutions to any outstanding problems within the group structure.
