Fabricate your Assignment 3 Revolved Surface. Your surface should fit in a 12″ x 12″ x 12″ volume. Refer to the videos below to create panelize your surfaces.
You will be fabricating you surface using bristol board paper. Please save your grasshopper (.gh) files to your dropbox folder. Refer to the syllabus for the file naming conventions for dropbox submissions. These are due before the next class on Friday 10/04/13. Late assignments will receive a grade penalty. Please bring your completed surfaces with you to class on Friday. We will be pinning them up and having a discussion.
You can view last year’s panelization class, as well. You can find the videos here:

Define a Revolved Surface in a 12″ x 12″ x 12″ volume. Refer to the video below to create your surface. Use the Panel component to describe and comment/label your definition.
Create a parametrically controllable revolved surface . Please save your grasshopper (.gh) files to your dropbox folder. Refer to the syllabus for the file naming conventions for dropbox submissions. These are due before the next class on Tuesday 09/24/13. Late assignments will receive a grade penalty. Please have your surface ready to and with you in class on Tuesday. We will be using these for the panelization lecture.
If you want to see what we will be doing with these surfaces you can view last year’s panelization class, you can find the video here:

Refine your surface from Assignment 08 in RhinoCAM. Using your milled “blue foam” surface as a starting point, what changes/refinements would you make? In this assignment you will be milling your surface out of HDU foam (see material sample images below). How might this new material affect your design and toolpaths? Follow the videos provided below and use the Rhino template and CSV tool set file provided on the Course Files page.
Come to class on May 15st with your RhinoCAM file completed through the roughing and finish toolpaths and a completed toolpath study performed using the InDesign template provided on the Course Files page. Remember all HDU surfaces/toolpaths must be approved by Professor Ringley before you mill them.
RhinoCAM Basic 3 Axis CNC Toolpathing Strategy
Do the Dip! If you are interested you can modify your surface to use the dipping milling techniques demonstrated by Professor Ringley last week. Video to follow, but please refer to the documents below.
An expanded CNC toolset for RhinoCAM which includes both the original cutters specified for your 3 axis assignment and the lolli cutters for patterning is now available on our course site:

The direct link to is available here:

As always, verify tool overhang length when loading any tools into the spindle to avoid collision.

Generate surfaces in preparation for RhinoCAM. Using the image map component tutorial from last week, create two surfaces from images. Don’t just download an image from the internet, but design one in photoshop/illustrator. Keep in mind that gray scale images tend to work best and images that have a gradual change in contrast from black to white areas. Also, feel free to experiment with different photoshop effects and filters. Hint: you might want to use the Gaussian blur.
Come to class on April 24th with your two surfaces and the images you used to create them. You will be using them in the RhinoCAM tutorial. Make sure they fit on the template file and that the surfaces fit in a 16″ x 16″ x 2″ volume.

Fabricate your responsive component. You should now have a responsive component in Grasshopper that responds to an input parameter control with a range of 0.0 to 1.0. Using the laser cutter as your fabrication technique create 3 versions of your component that represent 3 unique states of your component. You can choose any 3 values from 0.0 to 1.0 or you could use the end and middle conditions, for example 0.0, 0.5, 1.0.
