and f’
Bar machining: Outer surface near the edges, outer surface away from the
edges, end faces near the edges, end faces away from the edges
Pattern repetition : Outer surface near the edges, outer surface
away from the edges, end faces near the
edges, end faces away from the edges
Residual machining : Outer surface and end faces
Threading : Outer surface
Grooving : Outer surface and end faces
Necking : Outer surface near the edges, outer surface
away from the edges, end faces near the
edges, end faces away from the edges
End facing, single action, and sub–program calling
(3) When machining is suppressed in the area formed by points c, d, e’, and g
Bar machining : Inner surface near the edges and inner
surface away from the edges
Pattern repetition : Inner surface near the edges and inner
surface away from the edges
Residual machining : Inner surface and inner bottom surface
Threading : Inner surface
Grooving : Inner surface
Necking : Inner surface near the edges, inner surface
away from the edge
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 of the end face is not
included in workpiece length L’.
When a blank plate is machined, the point closest to the
chuck on the inner surface is used.
