DISCUSSION OF PRODUCT DESIGN The two design features for our go for were the rack pes holders and vehicle body cavity. When manufacturing the wheel base holders, we do a 0.5 diameter incinerate into a .7x.7 dapple of pol barelyhylene. 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 railway car conduct was an 8.00 in. long, by 2.00 in. tolerant by 1 in. thick disaster. The box had a trail out cavity proportion of 1 in wide, 0.5 deep, and 7.5 in long. We chose this dimension because it properly held two cars, with an bewitch 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 partly sit on top of the box, and their bottom half intimate of the cavity. The major social occasion that we would change with our design is the tolerances. betwee n 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 hazard 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. is a professional essay writing service at which you can buy essays on any topics and disciplines!

After we manufactured our part, we entrap that w e were actually close and inanimate on in ! some cases, with our parts. We found that there were some inconsistencies in the axel runs, in which the diameter of the cut fluctuated roughly .03-.07 mangle of the in demand(p) 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.
