(cutting end point) is less than that of A (starting point), the system executes X
positive tool retraction, otherwise, X negative tool retraction;
⑤
Axial(Z axial) rapid retract tool to Dn, No. n axial cutting cycle is completed. If the
current axial cutting cycle is not the last one, execute ⑥ ; if it is the previous one
before the last axial cutting cycle, execute
⑦
;
⑥
Radial(X axial)rapid tool infeed, and its direction is opposite to that of
④
tool
retraction. When the end point of tool infeed is still on it between A and A
f
(starting point of last axial cutting cycle) after the system executes X tool infeed
(
△
d+
△
i) (radius value) , i.e. Dn → A
n+1
and then the system executes
①
(start the
next axial cutting cycle); after the system executes the tool infeed ( d+ i), the △ △
end point reaches A
f
or is not between D
n
and A
f
, X rapidly traverse to A
f
and
executes
①
to start the first axial cutting cycle;
⑦ X rapidly traverse to return to A, and G74 is completed.
