During the first week in the shop we focused on making the linkage arms and the shafts for our most critical module. Before we start machining, we realized that using Aluminum for the arms is not a good way to go since its relativly heavy and pricy for what we want to make. Then we decided to use PVC for our links and confirmed with Davor that we are able to get some pvc pieces from the shop for free. Hooray~ By having our raw materials ready, we were about to start. We divided our team to two sub-teams. Juan and Jim were working on the links by using milling machine. Claire and Court were woking on the shafts by using lathe.
To start, we cut and faced our pvc block to be 1'' and 1/2'' thick, and sized them to the right dimentions. Then we used mill to drill holes on the link pieces in orde to place shafts. At the end of the week, we basicly finished the links except the holes on the side that need to be put set screws.
At the same time, Claire and Court were machining the shafts. We started by cutting the shafts to the right length. Then we used the groove cut-off tool to make grooves for E-clips. However, we met a problem that the surface around the grooves we cut were not flat. we asked John and he suggested us to use small fier to get rid of the small chips. That helped us a lot and the shafts looked much nicer. next, we used lathe to drill holes in the center of the shaft by using the #27 drill bit. Of course, we started by using the center-point drill bit.
I think we had a more clear idea on how we are gonna machine our parts after the first week. As we experience more in the shop, we will be more familier with the tools. Above are some pics of the things we have done during the first week, please check them out~ ^^
