(3) When machining is suppressed in the area formed by points c, d, e’,
and g
Bar machining : Inner surface, inner surface + automatic
residual machining
Pattern repeating : Inner end, inner mid
Residual machining : Inner surface and inner bottom surface
Threading : Inner surface
Grooving : Inner surface
Necking : Inner surface
Center drilling, drilling, and tapping
NOTE
When the origin of the workpiece coordinate system is on
the end face of the chuck, the length of the workpiece (L’)
is ignored. The machining allowance for the end face is not
included in workpiece length L’.
When RGH SHAPE (Casting or material for casting) is
selected, point X1 on the outer surface of a workpiece is
used.
(b) For internal claw chucks (turning tool)
