 Lastly, our group reassembled the product and we now propose a total of six design revisions to the DeWalt Angle Grinder. These revisions vary in scope and complexity from replacing simple components to system-level revisions. Overall these revisions aim to enhance the functionality and versatility of the angle grinder, and by extension increase sales and profitability. The simple component level revisions our group proposes can be found in [[Group_16_-_DeWalt_4_1/2_in_Angle_Grinder_Gate_3#Design_Revisions|Gate 3]]. The more complex system level revisions can be found in [[Group_16_-_DeWalt_4_1/2_in_Angle_Grinder_Gate_4#Design_Revisions|Gate 4]].
-Overall this project was a success as the gates our group has created contain a very thorough and in-depth analysis of this part. With this information in hand, we created several revision proposals that will allow DeWalt to improve this product and satisfy consumer demands into the future.

 The DeWalt 4 ½ in Angle Grinder is a heavy duty angle grinder designed primarily for professional use. By attaching a variety of different discs the product is able to perform a wide array of functions including, but not limited to, grinding, polishing, sanding, and cutting. Our group dissected and analyzed the components of this product in order to not only determine how it performs these functions, but also to find ways to improve it.
-The dissection performed in [[Group_16_-_DeWalt_4_1/2_in_Angle_Grinder_Gate_2| Gate 2]] allowed our group to analyze the subsystems, components, and their connections. The angle grinder delivers a high RPM torque to its disc by in-taking electricity through its power cord, delivering this electricity to the electromagnet and armature when the switch (controlled by user) was in the “ON” position, and then connecting the armature to a pinion and helical gear in order to deliver the mechanical energy to the disc. There were also many auxiliary parts that facilitated this overall process (i.e. a fan baffle). The complete analysis of all components can be found in [[Group_16_-_DeWalt_4_1/2_in_Angle_Grinder_Gate_3|Gate 3]].

-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.

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.

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.
