Decription
Ty Profile of a chuck (0: Chuck which holds a workpiece on the inner
surface, 1: Chuck which holdsa workpiece on the outer surface)
CX X coordinate of a chuck
CZ Z coordinate of a chuck
L Dimensions of the claw of a chuck
W Dimensions of the claw of a chuck (radius input)
L
1
Dimensions of the part of a claw at which a workpiece is held
W
1
Dimensions of the part of a claw at which a workpiece is held (ra-
dius input)
TY Specifies the profile of a chuck. When TY is set to 0, the chuck holding a
workpiece on theinner surface is specified. When TY is set to 1, the chuck
holding a workpiece on the outer surface is specified. The profile of the
chuck is assumed to be symmetrical with respect to the z–axis.
CX, and CZ Specify the position (point A) of a chuck with the coordinates of the
workpiece coordinate system. In this case, do not use the coordinates of
the machine coordinate system.
NOTE
Specifying the coordinates with a diameter or radius depends
on whether the correspondingaxis conforms to diameter or
radius specification. When the axis conforms to diameter
specification, spcify the coordinates with a diameter.
L, L1, W and W1 Define the profile of a chuck.
NOTE
Always specify W and W1 with radiuses. Specify L and L1
with radiuses when the Z–axis conforms to radius
specification.
