If the machine is a Fadal with a Fanuc control it is a relatively
new machine. The machine keeping up with the handwheel is possible on
machines with fast feed/rapid capabilities. I have one machine that I
think will keep up with the handwheel. A Mori Seiki MV-JR. It is a
very light machine with only 18 inches of X travel. Needless to say it
doesn't take many handwheel turns to move the full length of the X
travel.
The argument that the machine shouldn't try to be smarter than the
operator is the best argument against implementing the function I
would like to see. At that time I would like to see feedback to the
pulse generator to not allow it to over run the axis position. This
would make it like a manual machine in that it is harder to turn the
handle the faster you want to go. With the current handwheels this is
not possible. I see this requested function as compensating for the
limited feedback to the operator instead of limting the operator.
thanks
Stuart
