Research Paper on Design and Development of Multi-Purpose Machine

Machine design involves the design of a new concept or modification of an existing concept with improved performance. The need to increase productivity has realized many concepts where in the same machine performs two or more similar operations simultaneously, one such operation is cutting off. This operation is performed at the very beginning of the manufacturing cycle though it is essential it does not add any value to the product. Thus it is preferred that this cutting operation be done at a fast rate. Similarly drilling is common operation needed in any work shop. Grinding is needed to sharpen the tools and other finishing operation. Sander is needed to remove the burrs from edges. Buffing operation is needed to improve the surface finish of the work piece. Many designs have been proposed with the idea of operating multiple operations at the same time using a single motor arrangement. Normally these machines have been used with slider crank mechanisms with spring loaded feeding mechanism for cutting operation. The multi -purpose machine is a novel method where in the cutting is done with hack saws via slider crank mechanism delivering power using a high spur gear pair arrangement. The drilling operation is done via a bevel gear pair powered drill. The grinding wheel is mounted on the same shaft as the sander wheel only that sander wheel is powered by the spiral bevel gear box. The buffing wheel is mounted on the motor extension shaft that also drives the drill machine and grinding sander using an individual belt drive. The paper discusses work of the theoretical design of the components of machine operation is done and the solid model of the parts is done using Unigraphix Nx whereas the analysis is done using Ansys work bench.
