ii) When X coordinate in terminal of rough machining (XE) and
next machining start point (X2) is same or X coordinate in
terminal of rough machining (XE) is higher (In case of inner
diameter is “lower” ) than next machining start point (X2) .
XE → Z axis direction (next machining start point Z2) → X
axis direction (next machining start point X2) .

i) When Z coordinate in terminal point of rough machining (ZE)
is lower than next machining start point (Z2) .
ZE→Z axis direction (higher one of cutting start point Z1 or
machining start point Z1) → X axis direction→ Z axis
direction (next machining start point Z2)
higher one of cutting start point
Z1 or machining start point Z1.
