Фрагмент инструкции


It runs through normal 120-V alternating current power. When on, the saw blade has a stroke of 19/16 inches moving at a maximum speed of 2800 strokes per minute. The entire assembly, including the removable blade, weights 6.3 pounds. The saw has 6 speed settings, a trigger which determines whether the saw is on or off, and interchangeable blades. After completing the model and assembling it, we will attempt to animate several aspects of the construction and functions of the saw. Finally, we will end with an ANSYS analysis of the saw to determine certain limits, for example under what load the blade would break, and what would be the strongest material through which the blade can cut. Challenges: In undertaking our task, there are many difficulties that arise. First, the saw is designed for maximum user comfort. That means that the external shell is contoured for the human hand, with different grips and conveniences. These, as a whole, may be difficult to model in ProE. A second complexity will be precisely measuring the size of the pieces to ensure that our assembly comes together correctly. Because of the odd external shape, some of the internal components are also oddly designed. We must also take care in disassembling the model so that we do not damage any of the pieces. Finally, there are approximately 50 different parts to be modeled. Having that many parts to assemble creates complexities in and of itself.

Hopefully, we will animate the creation process, the normal function of the saw, and the removal/addition of a blade. After that, we hope to be able to use an ANSYS analysis to see the forces acting on different portions of the saw, focusing specifically on the blade and casing. Hopefully, we will be able to find the yield stress of the blade and the maximum hardness of the materials through which it can cut.

We do, though, reserve the right to change these responsibilities as necessary, or to suit a particular members strongest abilities.
