Cad design drawn. Laser cutter sorted. Acrylic glued. Piezo buzzers mounted and connected electrically. All really exciting. Look how the stage has progressed over these weeks;
After talking to our “mechanics consultant”, Tom, we decided to redesign the stage and the stage holder so that we could use the dvd head holder that comes with the dvd head. It has some nice features that we could take advantage of, such as a cog system which could be used for coarse movement of the dvd head over the sample, and screw holes that we could fit the precision screws into. This means we don¹t need to have such a complicated design, with the old dvd head and flexure stage abandoned. Continue reading Mechanics – Update Four
Today was an interesting day on a lot of levels! In the morning we bought acrylic from the architecture shop and then headed over to the high school to set the 3D printer going for a 10 hour print! After lunch, we headed to the shops to pick up some bicycle tires and clamps to make the floating platform that the AFM will rest on. Continue reading Mechanics – Update Three
Yesterday we worked on finishing up the CAD files for the DVD head holder and the flexure stage that will be used for coarse motion under the piezos. We also bought some foam and made the sound insulated box that will be used to shield the AFM. We bought some acrylic at the architecture department and will be going back to the high school to laser cut and 3D printing the various pieces we need to build the project.
Today we began printing and cutting the components for the pieces that make up the body and mechanics of our AFM. We visited Tsinghua High School to 3D print the casing to hold the DVD head, and laser cut the acoustic enclosure and lightweight scanner frame. Continue reading Mechanics – Update
In our attempt to build an AFM there are a number of technical challenges that we will need to overcome. Any nanoscale measurements have to be really sensitive as we are trying to measure really tiny things. Continue reading Technical challenges of the AFM
