Introduction:In Composite Assignment I made a mold on Shopbot.I made 3D shape of the botton in CATIA. then imported .STL file in PArtwork3D.

  • Following bottol shape imported in PARTWORK3D and assigned Roughing and finishing toolpath to make 3D model in wood on shopbot machine

    • Figure.1

          

  • I created roughing toolpath for rough cut It takes 2.30 Hrs to mill rough cut then for finishing it takes 30 minutes.

    • Figure.2

          

  • Preview of the milling Shown in following figure.I created half bottol shape in wood block.

    • Figure.3

          

  • Following Figure shows the shopbot consol setting

    • Figure.4

    Figure.4b

          

  • I cut that 3d part from wooden block using Scroll saw and right now dont have vacuume arrangement so i used one sided stick tape to cover my mold so whatever i am going to use to make mold wont stick directly to my wooden mold

    •       

  • I am using Cotton, String, Fevicol(Adhesive) with water.First i took water and fevicol in 1:1 ratio composition then Kept one layer of medical cotton then other layer of string as a fibers and again another layer of cotton.Then i poured the concentrated fevicol+water on that layer.

    • Figure.5

          

  • It took two days to dry and after two days because i have used plastic one sided stick tape to my mold i could easily release the part from wooden.

  • Following image shows the another side of composite materials after it gets dry.Strenghth of cotton with the string has improved.
