Week7

Computer-Controlled Machining

Group Assignment Link [I'm the hero of this week's group work!]

  • Test runout, alignment, speeds, feeds, and toolpaths for your machine
  • Document your work (in a group or individually)

    • Assignment

  • Make (design+mill+assemble) something big


    • This is our shopbot
    Workspace 1220*2440mm
    Through the group project, 12t birch plywood was cut using 6mm end mill
    We needed a gap of about 0.3mm for the joint


    This is a secret door project design in illust
    To celebrate our company's 5th anniversary, we will hang it at the entrance of Fab Lab


    Before turning to the shopbots, use a laser cutter to select a small sample size to check the ratio


    It was my first time dealing with a shopbot, so I practiced a lot
    I cut it in a 6mm down cut first, and I used a 3mm endmill to save the details


    the final result of using birch plywood


    First of all, I decided to make a frame for my final project using Shopbot
    I thought about how to implement Hanok for a very long time



    It is a traditional Korean building called Hanok


    I've been thinking about design almost all the way through the academy



    I started the 2D design with fusion360
    First, we set up our workspace with dotted lines


    We used parameters and mirror functions


    Draft Drawing of Completed Hanok


    Illustrator has cleared it up


    Shopbot can't cut the rectangle inside
    And don't let the cut slip out
    So I added a dogbone and a tab
    The dogbone makes joining easier


    I used a 3mm down cut end mill to do the pockets cut(See the bottom job sheet for more information)
    You need 0.1 to 0.3mm of clearance to make it easier to get in



    Jenny, the CEO of JennyandSito, who makes furniture for cats, has helped me a lot in making a tool path
    Thank you, Jenny


    Outline uses a 6mm compressor bit


    Compression bit has good performance in pocket processing(up-cut and down-cut combined bit)
    However, you need to set more depht than the parts that change from up-cut to down-cut (Set the depht bigger than b1)
    But if the Dephts is too big, damage to the machine comes fast


    Cutting completed(There's a cutting video bottom)
    I put the screw into the vertex and fixed it


    I painted the roof parts with spray
    Spray name [Montana mtn 94 - black]
    You need to spray it two or three times.
    It takes about 20 minutes to dry each
