+Using a .030" diameter end mill with amorphous diamond coating (<a href='http://www.harveytool.com/ToolTechInfo.aspx?ToolNumber=72030-C4'>Harvey Tool 72030-C4</a>), we machined the flexure from .020" Aluminum 2024 sheet in 2.5 minutes (comparable to the waterjet).

+Here is a 50% scale flexure (.010" beams, .015" gaps) machined from .020" thick Aluminum 2024 sheet using a .015" diameter end mill with amorphous diamond coating (<a href='http://www.harveytool.com/ToolTechInfo.aspx?ToolNumber=72015-C4'>Harvey Tool 72015-C4</a>).  It was fixtured using burnished PSA tape to both the substrate and the stock, with CA superglue applied between the tape layers.
