NOTE
If the V-axis (linear axis) is synchronized with the
spindle as in the case of dressing, the range of
movement of the V-axis is determined by the rotation
of the spindle. Accordingly, to perform dressing by
back and forth movement along the V-axis over a
certain range, the PMC must perform processing such
that when a certain position on the V-axis is reached,
the spindle is first stopped then reversed.
In the above example, limit switches are provided to
set the V-axis movement range, and control is applied
to the PMC to rotate a grinding wheel until the limit
switch positions on the V-axis are reached.
A position switch function is available to allow dressing
like that described above to be performed without
using mechanical limit switches. Moreover, by
rewriting parameter No. 5280 to No. 5299 for setting a
position switch operation range with the G10
programming parameter input function, a V-axis
movement range can be specified.
