The two design features for our project were the rack base holders and vehicle body cavity. When manufacturing the wheel base holders, we do a 0.5 diameter incinerate into a .7x.7 piece of polyethylene. This was to prevail the axle and wheel assembly. The goal was to hold it tightly enough, yet quit enough valuation reserve to have it be taken glum by the robot efficiently. Next, the car support was an 8.00 in. long, by 2.00 in. tolerant by 1 in. thick box. The box had a cut out cavity dimension of 1 in wide, 0.5 deep, and 7.5 in long. We chose this dimension because it properly held two cars, with an appropriate amount of tolerance so that they could be easily removed. The width of the box provided a disclose seat for the vehicles by having them partially sit on top of the box, and their bottom half inside of the cavity.
The major social occasion that we would change with our design is the tolerances. Between are two move that held the axles and cars, we would reduce the tolerances by 0.03 with axels and 0.03 with the car holder. Furthermore, we would improve the finishes. This would provide better and more consistent prospect for the axles and cars.
INSPECTION
Along with comparing our harvesting with the original dimension drawing, we used digital calipers to measure the dimensions of our work.
after(prenominal) that, we obtained some(prenominal) axle and car assemblies from the other groups and tested how well they fit into our holders.
After we manufactured our part, we found that we were very close and inanimate on in some cases, with our parts. We found that there were some inconsistencies in the axel supports, in which the diameter of the cut fluctuated roughly .03-.07 mangle of the desired dimension. We got 50 .43, .47, and .50. Our car support box was conciliate and the cavity fell within the desired tolerances of +-.03 with dimensions of 2.01, 8.00, and 1.01.
COST
To manufacture our part, we had a combined process time of 40 minutes as seen in...If you want to get a full essay, order it on our website: Ordercustompaper.com
