Hexapod's structural integrity is derived from the fact that elements
that comprise the equivalent of XYZ slides on a conventional machine are
either in tension or compression.
Once the screws on the 6 "legs" are calibrated, all machine accuracy is
derived from mathematics.
Controlling one with EMC would be interesting. EMC, and any other
conventional CNC program, assumes an axis move means controlling one
motor and monitering velocity and distance.
With a hexapod, something has to take that single axis move and perform
a lot of trig calculations. Contouring just makes things more
interesting. Adding additional axis at the workhead allowing
reorientation of the spindle would really add to the fun!
