here are the photos of the design, and the process
This week assignement is about composites, I thought to make a certain plate and did a design for it. during this time I was also preparing for my final project, which is olive harvester/shaker tool, and needed to make a stick, I tought in the beginning it should be aliminum but because aluminuim is difficult to process, Enrico had the idea to make the stick with cotton natural fiber. the stick of Enrico has certain details its a piece of 1m foam arranged to make one 2m foam piece enclosed with fiber in which will be attached the fork also, in a piece of wood, inside the stick foam is an aluminuim tube that contain 2.50m electrical wire. I like this idea too much and start the design. the foam is 1m and the stick is 2m long. so I designed higher and lower parts and their mirrors considering parts are thick on the bottom and getting a bit thinner on the top. I make some cuts on the top to hold a piece of wood. I made the design on fusion 360 of four parts I then prepare file for shopbot. Tiziano Berti did the editing of pocket and parallel setup x,y,z position and direction 6mm tool for foam, speed, geometry, heights, and passes. after milling the foam stick, I modify and adjust the four stick parts in a way to have the desired width and hole inside for the tube and electrical wire. then I used cotton natural fiber I cut 4 layers with 220 mm length and 25mm width and fifth layer with 220mm and 10mm width to use as the last one. Enrico and me covered the stick with the four first layers putting the end of layer with the beginning of the next one and so on. last laye is the thinner one. all layers were tighten as much as possible. then I prepare epoxy resin A and B mixture according to indications. and apply on the cotton fiber stick to harden the material. its better to have cotton fiber cutted with laser cutter before applying resin, as this will help getting more fine result, I obtain good result.
