CANNED CYCLE
/MULTIPLE REPETITIVE
CANNED CYCLE
General
This option canned cycles to make CNC programming easy. For instance, the data of the
finish work shape describes the tool path for rough machining. And also, a canned cycles
for the thread cutting is available.
The following example shows stock removals in turning type I.
If a finished shape of A to A’ to B is given by a program as in the figure below, the
specified area is removed by
∆
d (depth of cut), with finishing allowance
∆
u/2 and
∆
w left.
C
•
d : Depth of cut (radius designation)
Designate without sign. The cutting
direction depends on the direction
AA'. This designation is modal and is
not changed until the other value is
designated. Also this value can be
specified by the parameter (No.
5132), and the parameter is changed
by the program command.
e : Escaping 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.
5133), and the parameter is changed
by the program command.
ns : Sequence number of the first block for
the program of finishing shape.
nf : Sequence number of the last block for
the program of finishing shape.
•
u : Distance and direction of finishing
allowance in X direction (diameter /
radius designation).
•
w : Distance and direction of finishing
allowance in Z direction.
f,s,t : Any F , S, or T function contained in
blocks ns to nf in the cycle is ignored,
and the F, S, or T function in this G71
block is effective.
