ADDITION OF CANNED CYCYLE AND
MULTIPLE REPETITIVE CYCLE
The following program generates the cutting path shown in Fig.
13.2.5. Chip breaking is possible in this cycle as shown below. If X
(U) and P are omitted, operation only in the Z axis results, to be
used for drilling.
G74R (e) ;
G74X(U)_ Z(W)_ P(∆i) Q(∆k) R(∆d) F (f ) ;
e :Return amount
This designation is modal and is not changed until the other
value is designated. Also this value can be specified by the
parameter No. 5139, and the parameter is changed by the
program command.
X : X component of point B
U: Incremental amount from A to B
Z : Z component of point C
W: Increment amount from A to C
∆i :Movement amount in X direction (without sign)
∆k: Depth of cut in Z direction (without sign)
∆d :Relief amount of the tool at the cutting bottom. The sign
of ∆d is always plus (+). However, if address X (U) and ∆i
are omitted, the relief direction can be specified by the
desired sign.
f : Feed rate
