Now that the inlay material is affixed to backing material and the template is taped to the inlay material it's time to clamp the entire assembly to the workbench. There are two goals you want to achieve when clamping the assembly down. First is so nothing moves but the router during the cutting process (probably have heard that before!), the other is to ensure the clamps do not interfere with the router base.
In the first picture you'll notice the clamp is positioned over the template itself. This is always preferable if possible. In the picture, but you can't see it, there is a small piece of wood under the template that is the same thickness as the inlay material being cut. This is needed so the template doesn't flex and get pulled away from the inlay material.
The second thing you need to be aware of is if the clamps will interfere with the router base when making the cuts. This is far more important when cutting inlays rather than voids. If you're cutting a void and the router base bumps a clamp you can always reposition the clamp and continue cutting the void. If you're cutting an inlay, however, and the router base bumps the clamp you just ruined your inlay piece and will need to cut out another one.
It's always a good idea to take your router and guide it around the shape you're cutting out prior to turning on the router. That way if the clamp interferes with the cutting process you can fix it before any dame is done. After you're sure the clamps are out of the way, turn the router on, plunge it into the material, and make your cut.
