Symbol Description
TY Chuck–shape selection (0: Holding the inner face of a tool, 1: Holding the outer
face of a tool)
CX Chuck position (along X–axis)
CZ Chuck position (along Z–axis)
L Length of chuck jaws
W Depth of chuck jaws (radius)
L1 Holding length of chuck jaws
W1 Holding depth of chuck jaws (radius)
TY :
Selects a chuck type, based on its shape. Specifying 0 selects a chuck
that holds the inner face of a tool. Specifying 1 selects a chuck that
holds the outer face of a tool. A chuck is assumed to be symmetrical
about its Z–axis.
CX, CZ:
Specify the coordinates of a chuck position, point A, in the workpiece
coordinate system. These coordinates are not the same as those in the
machine coordinate system. Table 1 lists the units used to specify the
data.
WARNING
Whether diameter programming or radius programming is
used for the axis determines the programming system.
When diameter programming is used for the axis, use
diameter programming to enter data for the axis.

Define the shape of a chuck. Table 2 lists the units used to specify the
data.
WARNING

programming is used for the Z–axis, specify L and L1 in
radius.
