Question

Windshield

Gurus,

Is anyone out there creating windshields? If so what techniques are being used to make sure the curvature is nice and smooth, especially on the edges? I am having problems getting good curvature/transition on the edges.

Thanks for any advice/suggestions that you may give.

    Just my $0.02,

    You may want to make your windshield surface intentionally oversize
    initially, and then trim the profile using a cut, etc... This may help
    preserve the proper curvature out at the edges, corners, etc...

    Agree. Overbuild, trim and build in curvature continuous surface patches
    where required. Conics are often helpful.

    Windshields (auto glass)...as with all (most) body design features are not "mathematical".It is"developed" geometry. Yes, whilethe corner radii "cuts" can be true radii or some type of conic, the spline they attach to will likely not be anything "ruled". The overbuild technique is sound but watch your final shape cut(s). Auto glass is formed while hot and thus has unique edge conditionsthat usually flow non-normal to the A surfaces.
