I just had very complicated granite tops made by an outfit that had a
CNC water cutting robot. And I got to see them cut it. The damn
thing could literally cut ANY shape and with no dust, just high
pressure water. If you could find someplace with a computer
controlled water cutter they probably wont even charge for the complex
cuts, but everyone charges to the nearest full rectangle, IOW you pay
for all the waste. The cutting head not only moved on x/y axis but
could also angle the jet so deep bevels, under-cut bevels etc could be
done just as easily as a straight line. I was not upcharged for any
of my detailed cuts, I just paid for the total square footage
including waste. The only thing the water jet couldnt do was the ogee
edge, but a different router table did that, also with the slab
submerged in water so no dust.

Why would someone who has a CNC cutting machine not charge for complex
cuts? They did spend a few bucks for the machine and someone has to know
how to program the work.- Hide quoted text -

The designer measured, went back to his office; entered the drawings
into a CAD program, a few days later he brought the cad drawing back
to my house to re-verify all the measurements. (he measured within
1/16 inch tolerance no wiggle room). I signed off on the job, when
they scheduled my job I asked if I could see them cut it. It was so
simple, the designer downloaded the drawing to the machine from his
CAD program, the operator selected and positioned the starting 0,0
coordinate over the slab and pushed a button, the robot did the rest.

So they have relatively the same labor costs for complex or simple
designs, thats how they can charge the same. The machine pays for
itself in volume as they can process more granite than a manual labor
shop, and not have to pay the health insurance costs for siliconosis
poisoning due to dust.

The installers came with the slabs and they slid right in tight.
