In pattern repeating, when each X coordinates of rough machining
terminal point (XE) are lower than next machining start point (X2) , the
retract position of X axis direction is higher one of cutting start point or
first machining start point.
The tool always moves to a constant point and it becomes the following
cycles.
S Cutting start point
S Machining start point X1
S Machining start point X2
S Machining start point X3
Z3 Z2 Z1

i) When X coordinate of in terminal of rough machining (XE)
is lower than next machining start point (X2) .
XE→X axis direction (Higher one of cutting start point or first
machining start point) →Z axis direction→X axis direction
(Next machining start point X2) .
