1. AXIS CONTROL
125
Suppose that a machine has the X1-- and Z1--axes belonging to path 1 and
the X2-- and Z2--axes belonging to path 2 and that a workpiece moves
along the Z1-- and Z2--axes as directed by move commands. The
following examples interchange commands between the X1-- and
X2--axes.
(1)Independent control
Machining is performed by a path 2 program.
X1
Turret 1
Workpiece 2
Workpiece 1
Z2
X2
Z1
Turret 2
Machining is performed by a path 1 program.
(2)Composite control
Machining is performed by a path 1 program.
Turret 1
X1
Workpiece 2
Workpiece 1
Z1
X2
Z2
Turret 2
Machining is performed by a path 2 program.
During composite control, the X2-- and Z1--axes are moved by a path 1
program, and the workpiece coordinates of the X--axis in path 1 indicates
the position of turret 2. Similarly, the X1-- and Z2--axes are moved by a
path 2 program, and the workpiece coordinates of the X--axis in path 2
indicates the position of turret 1.
