As of 2012, OSE migrated to this method of prototyping - essentially to allow 1 month of preparation and 1-2 day builds:
- Extensive preparation - CAD and fab drawings
- Usage of Fabrication Diagram Method
- Migration towards CNC torch table cutouts as in Digital Master Index
- Collaborative Production Runs - parallel builds with many people
- Scale Modeling of devices prior to builds - test-driven development
- Fabricator Training via assembly of scale models by Collaborative Production Run participants
- 2 Hour Training Session for participants on shop procedure, safety, and tool use
Torch CAM Detail
- Label libraries and dimensions in LibreCAD, not in google docs - to make it easier to make updates to drawings. Use Google Docs for publishing only for additional notes and comments.
To accomplish the above, these Design roles can be taken on in parallel:
- CAD generation
- Documentation of preparation for the production run (CAD, procedures, logistics) according to Documentation Standards for Collaborative Prototyping
- CAM generation
- Economic Analysis
- Ergonomic Analysis - determines the time required for a complete build based in 30 IPM cut through 1/2" mild steel with a 55 amp plasma cutter. See Plasma Cutter Cut Speed as a Function of Metal Thickness.
