V-grooving PALBOARD is an excellent method that helps industrial designers turn a 2D panel into a 3D object.
For V Groove Milling\\Routing, use a machine bit designed for bending applications. Such bits offer top angles of 90°, 120° or 135°.
A 90° bit produces rectangular bends with almost no gaps.
120° or 135° rounded tip bits produce acute angled bending of up to 90° with approx. 2 mm gap between the sides.
Make sure not to route through the PALBOARD panel. Leave 0.6 mm to 0.8 mm, so you can benifit from the structural strength of this matrial.
