4.12.1 Chucking Equipment in Simulation
Clamping G65
G65 displays the selected chucking equipment in the simulation
graphics. G65 needs to be programmed separately for each chuck.
G65 H.. without X, Z cancels the chuck in the simulation graphics.
Chucks are described in the database and are defined in CHUCKING
EQUIPMENT (H=1..3).
Parameters
H:
Chuck number (H=1..3: Reference to CHUCKING EQUIPMENT)
X, Z: Starting point – position of the chuck reference point (X
diameter) – Reference: Workpiece zero point
D: Spindle number (reference: CHUCKING EQUIPMENT section)
Q: Chuck shape (only for chuck jaws) – default: Q from the
CHUCKING EQUIPMENT section.
Chuck reference point
”X, Z” defines the position of the chucking equipment in the simulation
graphics.The position of the reference point depends on the clamping
form (see illustration).
The CNC PILOT mirrors the chucks ”H=1 to 3” if they are positioned
to the right of the workpiece.
Note on the simulation graphics and the reference point:
■ H=1 – chuck
■ ”Open” chuck is displayed.
■ Reference point X: Chuck center.
■ Reference point Z: Right edge (account for width of chuck jaws).
■ H=2 – chuck jaw (”chuck shape Q” defines the reference point and
internal/external clamping)
■ Position of the reference point: see illustration at upper right
■ Internal clamping: 1, 5, 6, 7
■ External clamping: 2, 3, 4
■ H=3 – chucking accessory (dead center, lathe center, etc.)
■ Reference point in X: Chuck center
■ Reference point in Z: Chuck tip

Program NC blocks containing G65 with
”slide code $..” if your lathe has more than
one slide. Otherwise, the system displays
more than one chuck.
