During the week of the 22nd to 28th we were concentrated on making the most critical module for our project, as the 8th milestone required us to complete this part by Wednesday. As we have made most of the major parts to our MCM previously, we worked on the smaller parts in our module (for instance the L pieces connecting the top of the sweeping arm to the motor platform on which the platform will sit, or the pinion, which will allow the motion of our sweeping arm in the slot).The L pieces, mentioned previously, were very hard to machine, as we had to drill the holes after bending the aluminum pieces. The bending of the pieces complicated the placement of holes on the L piece, and initially led to some unwanted shaft misalignment, which was later fixed.
However, the MCM was only one part of the MS8 assignment. For MS8 we finalized our bill of materials and manufacturing process for the whole machine. For the materials, we are seeking to purchase a larger architectural tube (2 inches by 1 inch with 1/8th inch thickness) and also another 1/4 inch diameter aluminum rod for the motor/wheel shafts.
This is a small copy of our full bill of materials:
Here is a small copy of our full manufacturing plan:
We are currently looking forward to manufacturing the rest of the rest of the parts during the break (for other modules, including the frame, the scoop, and the wheels), as well as beginning to test out our design.
