20. AXIS CONTROL FUNCTIONS
581
(1) When the master axis is the spindle, and the slave axis is the C–axis
1.
G81.5 T10 C0 L1 ;
Synchronization between the master axis and C–axis is started at
the ratio of one rotation about the C–axis to ten rotations about the
master axis.
2.
G81.5 T10 C0 L–1 ;
Synchronization between the master axis and C–axis is started at
the ratio of one rotation about the C–axis to ten rotations about the
master axis.
In this case, however, the direction of rotation is opposite to that of
1. above.
3.
G81.5 T1 C3.26 ;
Synchronization between the master axis and C–axis is started at
the ratio of a 3.26–degree rotation about the C–axis per one rotation
about the master axis.
4.
G81.5 P10000 C–0.214 ;
Synchronization between the master axis and C–axis is started at
the ratio of a –0.214 degree rotation about the C–axis to 10,000
feedback pulses from the pulse coder of the master axis.
(2) When the master axis is the spindle, the slave axis is the V–axis (linear
axis), and inch/metric conversion is performed
1. For a millimeter machine and metric input
G81.5 T1 V1.0 ;
Synchronization between the master axis and V–axis is started at
the ratio of a 1.00 mm movement along the V–axis per rotation
about the master axis.
2. For a millimeter machine and inch input
G81.5 T1 V1.0 ;
Synchronization between the master axis and V–axis is started at
the ratio of a 1.0 inch movement (25.4 mm) along the V–axis per
rotation about the master axis.
(3) When two groups of axes are synchronized simultaneously
Based on the controlled axis configuration described in Fig.20.8.5,
the sample program below synchronizes the spindle with the V–axis
while the spindle is synchronized with the C–axis.
