Chucking equipment in simulation 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 the
CHUCKING EQUIPMENT section (H=1 to 3).
The Chuck reference point determines the position of the chuck in
the simulation graphics. The position of the reference point depends
on the chuck shape (see illustration). The chuck reference point is
dimensioned with respect to the workpiece zero point.
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:
„ Is depicted open
„ Reference point X: Center of chuck
„ Reference point Z: “Right edge” (take into account the width of
the chuck jaws)
„ H=2 – Chuck jaw (Q defines the reference point and inside/outside
clamping):
„ Position of the reference point: See illustration for G65
„ Inside clamping: 1, 5, 6, 7
„ Outside clamping: 2, 3, 4
„ H=3 – Chucking accessory (dead center, lathe center, etc.):
„ Reference point in X: Center of the chucking equipment
„ Reference point in Z: Point of the chucking equipment

Parameters
H Chuck number (H=1 to 3; reference to CHUCKING
EQUIPMENT)
X Starting point—Chuck reference point (diameter value)
Z Starting point—Chuck reference point
D Spindle number (reference: CHUCKING EQUIPMENT
section)
Q Chuck shape (only for chuck jaws)—(default: Q from the
CHUCKING EQUIPMENT section).
On lathes with multiple slides, program the NC blocks
containing G65 with “slide code $..”. Otherwise, the
system displays more than one chuck.
