Re: [CAD_CAM_EDM_DRO] Parabolic cookers & Vector 9

All you really need is a CAD program ...like Rhino... that will generate a
surface based on a line.

Draw the parabola, "sweep a srface as long as you need. Save this as a .dxf
(or whatever you use) for generating the gcode program. Mill the part from
aluminum and your all set.

>We recently participated in a short discussion about parabolic solar

cookers on another forum. I thought I would share a web page with a few
notes about how we attacked the project in Vector.
http://www.vectorcam.com/cooker/ It was pointed out that the round design
was a good way to heat the ends of a Hot Dog, but that a long trough might
be a better design. ;-) There is a downloadable excel spreadsheet that
generates a parabola spline which can be pasted into Vector to develop the
design for variable focal lengths. Additional comments about the approach &
concept are appreciated.
