Senior Project Manufacturing

This week more progress was made on the bogie. The tubes that connect the bogie were cut on one of the automatic hacksaw. The side plates of drive bogie were then welded to these tubes. Because the tubes didn't fit exactly in the holes that were cut out by the waterjet was too small. To solve this, the walls of the drive bogie (where the tubes slotted in) were filled down if not angle ground. After the tubes were slotted into their correct positions and welded into plate. After the other side plate of the Drive bogie was slid into place and welded ensuring that the tubes would not shift. The route selection has also had some work done, having both ends bored out so that the internal diameter is exactly 62 mm. The outer diameter was going to be skinned but it was decided that it would be unnecessary as it would likely take up multiple cutting tools on the lathe. This may pose a problem for the final assembly of the drive bogie but as we have found from the track team that even if the 3rd rail is manufactured, it is unlikely that it will be assembled. Since we dont have to finalize the route selection system, we can prioritize other aspects of the manufacturing and making sure that the rest of bogie is made correctly and to spec. Worst case scenario we can leave it for future teams to improve on as our primary focus for this year was to separate the bogie into a two-part system (drive and slave).
