Design and build a holder using 2.5 axis routing techniques introduced this week. The holder can function for people (chair, stool, bench, head-rest) or for things (book shelf, laptop stand, table). Consider using .75″ or 1″ MDF as your material.
Post Rhino files and images of the finished piece on this blog.
Should reservations availability on the Morrison CNC router post a problem, please contact Ali and Zach by email.
NOTES on processing your design for 2.5 axis routing job:
open Machine Operations (MOP) Browser from “RhinoCam 2.0” menu
open Tool Library Browser from the “RhinoCam 2.0” menu
In the MOP window, under the “Create” tab, click on “Stock – None” and indicate the size of your stock material [brownish stock material should be visualized]
Under the “Create” tab of the MOP window, select “Profiling” from the “2.5 Axis”
Under the “Maching Features/Regions” tab, indicate the curves in your design that are to be profiled
Under the “Tools” tab, indicate the tool you wish to use for .
Under the “Feeds and Speeds” tab, indicate appropriate parameters (refer to CMU dFAB “White Book”)
Under the “Cut Levels” tab, indicate “Total Cut Depth” (thickness of your material for profiling) as well as the number of passes (“Rough Depth/Cut”)
Under the “Cut Parameters” tab, select “Outside” or “Inside” depending on the type of profiling
If your design requires “inside edge” profiling as well as “outside edge”, repeat the above steps for your inside profiles also
NOTES on creating designs in Rhino for 2.5-axis routing:
Create two rectangular curves that represent the bottom and top surfaces of your stock material
Place bottom left corner of your stock material at the origin
Your geometry (all curves) should be planar and placed at the TOP of your stock material
TIPS
In your RhinoCam generated g-code, change “M61” to “M61.1” in order to turn on only the front 1/2 the vacuum table
