I Programming
a. Single block
When the canned cycle operation is performed by using the single block mode, normally, it is
separately stopped at the terminal of the movements 1, 2, 3, 4, 5 and 6 in the Fig. 13.1 (A). And the single
block is somewhat different according to corresponding canned cycle action at the bottom of a hole. For
example, the single block is stopped when the dwell is applied. The operation at the bottom of the hole for
fine-milling and rough-milling are divided into multiple single stop. So, it is necessary to startup for several
times to machine a hole in a single block.
b. Feed hold
The feed hold is disabled between the movement 3 ~ 5 in commands G74 and G84, but the indicator of
feed hold will light up. But the control stops till the operation 6. If the feed hold is performed again in
operation 6, then it is stopped immediately.
c. Override
The feedrate override is considered for 100 percent in the operation G74 and G84, the override change
is disabled.
(9) When the bit 1 of parameter 3 (D_R) is set to 1, the D value in tool compensation page indicates
diameter value.
3.24.5 Examples for Modal Data Specified in Canned Cycle
No. Data Specification Explanation
N0010
G00 X_ M3
；
G00 positioning at the rapid traverse, and rotating the spindle;
N0020
G81 X_ Y_ Z_ R_
F_
；
Because it is the beginning for the canned cycle, so the value
needs to be specified for Z, R and F.
N0030 Y_
；
The corresponding hole machining data is same to the previous
hole, only the position Y is different, so G81Z_R_F_ can be
omitted. As for the hole position is shifted for Y, hole machining is
performed further by using the G81;
N0040 G82 X_ P_
；
The hole position needs to be moved along the X axis as for the
pervious one. The Z, R and F of previous hole and the P specified
by this hole are taken as hole machining data by the G82;
N0050 G80 X_ Y_ M5 ；
The hole machining is not executed, all of the hole machining data
are cancelled (except for the F); The GO positioning is performed
with XY;
N0060 G85 X_ Z_ R_ P_ ；
The Z and R are needed to be specified newly because all of the
data in previous block are cancelled, the above value specified is
applied when the F is omitted. Although the P value is commanded,
but it is not needed for this hole machining, so the P value is saved.
N0070
X_ Z_
；
The Z is different compared with the previous hole, and the hole
position just moves along the X axis;
N0080 G89 X_ Y_ D_ ；
The Z and R, P values separately specified by N0070 and N0060,
the F value specified in N0020 are taken as hole machining data,
which are used for G89 hole machining.
N0090
G112 I_ J_ F_ D_
；
The fine-milling hole machined by G89 is performed by G112.
N0100
G0 X_ Y_ Z_
；
positioning for a rectangle machining
N0110
G134
Z_R_I_J_K_U_D_
；
Start machining the rectangle;
N0120 Y_I_J_K_U_D_ ；
Begins machining the second rectangle;
