Axis resolution/distance per rotation
The resolution parameters operate in the same way as the standard X,
Y, Z axes. If you enter 360 or 36 as the distance per rotation, then
you can program the 4th axis as a rotational axis in degrees or 1/10 of
a degree.
Homing offset
The homing or reference offset defines the angle differential from the
zero position after moving clear of the switch. WinPC-NC first looks
for the switch at search speed and then moves back from the switch
in the opposite direction. Following this, the reference offset is
moved as a rotation round to the zero position.
Adjusting
tangential
cutter
Using the 4th axis as tangential axis the reference offset has to be
adjusted in the way that the cutter edge shows in positive X direction
after the reference move.
Axis 4 programmable as
Letter for
programming
The 4th axis can be addressed in G code programs using various axis
letters. Axes parallel to X, Y, Z are normally designated U, V, W,
while rotational axes in the X, Y, Z direction are programmed with
A, B or C.
Homing sequence of 4th axis
The reference movement of the 4th axis can be performed either
before or after the other axes.
