Th J25: CDR, CAM reviews begin, Machining begins
- Your CAM should be done or nearly done.
- Make an engineering drawing for your part that provides basic dimensions, stock size, and location of mounting holes. Email as a single .PDF file to medesign@seas.upenn.edu (title both the file and email as "501-CANDY-STOCK-PennKey") before class by 2:00PM. We will use these to help you acquire the necessary stock.

Deliverables
1. Completed desk candy.
Guidelines
*Cutting time will be scheduled in 3 hour time slots. Scheduling coming soon!
- You must have a maximum simulated cutting time of 2 hours.
- You are responsible for preparing your stock and making any requisite fixturing (other than the provided fixture plate) before your machining time slot.
- Anodization will be available as a finishing process. For anodizing, the part/s must be aluminum only (pressed in steel pins or other materials will ruin your part) and must have a 1/4-20 tapped hole somewhere. A custom adaptor can be made for your part that includes this tapped hole.
Materials
We have dedicated 6061-T6 aluminum stock for use in Candy. Other stock is subject to availability and speaking with Pete.
- Stock: 1.5" x 4", and 2" x 4.5" bar.
- Screws: 6-32x0.75", 6-32x1", and 6-32x1.25" alloy steel fasteners.
Setup (MiniMill)
- The Haas will be pre-configured with a steel fixture located against a stop in the vice, with the X-Y zero set as indicated here. The part Z-zero should be set to the top of the fixture.
- #6-32 alloy steel fasteners will be provided to attach your part to the fixture plate.
- The tools listed in the tool table will be loaded into the toolchanger, all zeroed to the top of the fixture.
- The Minimill tool table for Candy can be found below:
