Biconic Surface, Acoustic Reflector

Hello,

I'm trying to design an acoustic reflector in SW, (I just purchased the
2006-2007 student edition). I am able to make a parabolic mirror by
doing a revolving cut of a parabola sketch. For example, if the central
axis of the reflector/mirror is the z-axis, then the surface changes
depth with the radius from the z-axis. So it is symmetric about the
z-axis. But does anyone know if it's possible to model a biconic
surface? A biconic surface is not symmetric about the central axis. For
example, if the central axis is the z-axis, a biconic surface will vary
its depth with both x and y. I have the equation for this surface, but
how would I model it in SW so that it can be machined?

Thanks,

Stefan

 

I believe what you want to do is sweep a conic section along a conic trajectory
maintaining a constant, parallel co-planar axes, section normal direction.
Maybe someone will come along and help with a Solidworks specific method of
accomplishing that or something more expedient if it's not readily apparent.
