19.9.4 Sample Programs
- 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 (a) 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.
- 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.
