Does anyone on Orchid have experience with FREE-HAND water-jet
carving in stone?
wiki/Water_jet_cutter tells us the accuracy is down to.005 inches
(.13 mm). That is around the limit of human perception (mine anyway).
The 5 axis waterjet stone cutter is now ubiquitous, wiki correctly
tells us. Any Google search will confirm that. That is high school
geometry X, Y,Z plus A and C axes which as I understand it takes us
into the concept of degrees of freedom (dof) in robotics. Correct,
Mr. Livick? BTW how many dof are there in gymnastic arts?
The human dof of a stone carver far surpass those of any robotic
carver (again subject to correction by experts) but the limitation is
set by the power and accuracy of the carving/grinding “end effector”.
As I Googled on suppliers of waterjet equipment I came across a
picture/video of naval workers fully garbed from head to toe while
they scaled down a ship with waterjet equipment. Coincidentally I was
also studying some cave woman stone carvings at the same time in
those big library tomes with titles like “Art Atlas”. Alas, cave
woman did not have waterjet, nor did the Mount Rushmore carvers so I
wonder - would waterjet as the state of the art stands right now have
done the job better?
The pressure of course is enormous and in the 40-100 PSI range. But
a free hand cave woman, safely suited with a pressure washer on
steroids could do ________ what with a 10 ton block of granite?
