10.4 ELECTRONIC GEAR BOX AUTOMATIC PHASE
SYNCHRONIZATION
In the electronic gear box (EGB), when synchronization start or
cancellation is specified, synchronization is not started or canceled
immediately. Instead, acceleration/deceleration is executed first.
Therefore, synchronization can be started or canceled while the
spindle is rotating. Also, synchronization ratio can be changed while
the spindle is rotating.
At synchronization start, automatic phase synchronization is
performed such that the workpiece axis position matches the position
corresponding to the spindle one-rotation signal. With this
synchronization, the same operation is performed as synchronization
start caused by a one-rotation signal in hobbing synchronization when
using the functions of a hobbing machine.
The spindle corresponds to the EGB master axis and the workpiece
axis corresponds to an EGB slave axis.
