This project investigates the dynamic behavior of an excess material unload station on an indexing machine used by the sponsor company. This station is used to remove material left over from operations performed previously in the machine. Failure to remove material at this station causes a stop in machine operation, which is undesirable. Investigation of potential causes for this failure included testing the machine with accelerometers, recording high-speed video of the machine in operation, and researching potential errors by discussing station operation with engineers and mechanics familiar with the machine. Results of this investigation showed that the likely root cause of this error was a related problem happening at an upstream station. With this information, it was decided to redesign the current station to achieve the same operation with a similar system. The proposed system redesign utilizes one less cam and five fewer links than the original design.
