week 11 die switching mechanism

This week me in and I couldn't manage a time to meet, so I stayed home and did some design on the quick die-switching mechanism since the bender is being built at his house. I did some research about expandable die, similar to a transforming table where it transforms from a small circle to a larger circle. This mechanism require extreme precision and internal design. So what I think is most suitable is to make multiple dies with different desired redii and develop a quick switching mechanism to quickly switch out different dies so the future bending and testing can be done easily. Below is some sketches of the design.

Week 10: individual writing assignment #2 and plotting 1:1 scaled drawing.

The second individual writing assignment is due this week on 11/9/2016. I worked on that as well as the plotting the actual curve onto multiple pieces of paper.

From previous week, i confirmed that the intended curve radius from last year was 20". After some research on how plot 1:1 drawing, I used Sketchup to make the drawing and export it as a PDF file. then use adobe PDF reader to print the drawing as a poster in Sketchup does not allow me to print with multiple paper.

Result was successful:

Week 9 - measurement of previous team's product

I measured the curved aluminum of the 3 corners of the track. the forth corner is missing so theres no data from it. I measured it using a compass and a ruler. I took 3 measurements from each bent aluminum and averaged them. Aluminum#2 and 3 is somewhat consistent but aluminum number 1 had a reading of 22.625" radius that is not acceptable. I assumed that the previous team did not have a consistent machine that do the bending.
