View Resource Enhanced Waterjets Slice Costs

Cutting edge waterjet innovations are the subject of this February 2003 feature from Forming & Fabricating, a publication of the Society of Manufacturing Engineers. Extremely high pressure nozzles are being developed to improve cutting speed and lowering costs, and enhanced software for controlling machine movements is also a focus of study.

View Resource Electrochemical Machining Carves out Nanostructures

This news article from June 20, 2003 published by Great Britain's Institute of Physics, describes an electrochemical machining process that is being used to fabricate complex nanostructures. The work, produced by German and U.S. researchers, has the potential to compete with current lithographic processes.

View Resource Caltech Micromachining Laboratory

Entirely different and exotic machining techniques are required for creating microelectromechanical systems (MEMS) and other extremely small devices. The Caltech Micromachining Laboratory maintains this archive of research highlights and papers on its homepage, including a paper on a MEMS-driven flapping wing for a palm-sized aerial vehicle.

View Resource Waterjet Videos

The Waterjet Video Vault contains clips of waterjet machines in action. The video of the foam cutting procedure is especially interesting, as it shows how quick and accurate the machining process can be. Other videos include a waterjet nozzle fired into the air; drawing up a part in CAD, making a tool path, then starting the cut; tilting the cutting head; and cutting 1/2" piece of aluminum. The...

View Resource The Permaculture Research Institute

The Permaculture Research Institute (PRI) describes permaculture as "the harmonious integration of landscape and people providing their food, energy, shelter, and other material and non-material needs in a sustainable way. It is also the conscious design and maintenance of agriculturally productive ecosystems which have the diversity, stability and resilience of natural ecosystems." In addition...
