That I can't tell ya. Mkawa could probably help you out with that as he has had plates made with and without notches for the exact same plates in Ti.

If you have to slow it down to something like 1/2 the speed, you can figure out the time/cost difference between cutouts.

Tonight I did a back of the napkin calculation to try to give some sort of context to Melvang's comment about the price of cutting going up based on the complexity of the cutout. This is totally a rough calculation which does not have a direct monetary representation, but it will give you an idea. Basically, these numbers represent the length of the cut or the outline of the switch, plus a static value for each corner to account for the machine having to slow down. Again, this is totally a rough calculation just to illustrate the point.

Basically, each of these values is the length in mm, plus 1mm per corner to account for the slow down. So for the basic cutout you get 7+7+7+7+4 = 32. Make sense?

Hopefully this gives some proportional idea how much more expensive the more elaborate cutouts will be.
