2.8, 5 DWELL (G04) (Cent’d)
(3) The maximum length of time which can be
designated with address U or P is as fol-
lows .
Dwell time: 0.001 to 9999.99 seconds
Dwell time is not influenced by input/output
increment.
EXAMPLE :
G04 U3.5 ...
3. 5-second dwell
G04 P3500 . . .
3. 5-second dwell
Notes :
1.
G04 is a non–modal G code.
2. The counting of dwell time is started from
the instant the control enters the ERROR
DETECT ON state upon completion of the
move command block before G04.
Therefore, with G04 UO ; , the control
advances to the next block immediately
after detecting the ERROR DETECT ON
state.
EXAMPLE
GO1 W-1. F25 ;
— 1 mm feed
G04 UO.2 ;
— O. 2 second dwell time
GO1 W-1. ;
— 1 mm feed
With the above program, chip cutting feed
is obtained.

2. 8.6 TOOL OFFSET VALUE (G 10)+
With G 10 command,
tool offset values can be
set and corrected.
(1) G1O P-. . X(U). . Z(W) C.. R... ;

Table 2, 12
Meaning
P For specifying tool offset No.
x
For changing the tcol offset value to the
z specified value.
u
For adding the specified value to the original
w tool offset values.
For changing the tool radius to the specified
R
vai ue.
The offset values for which no address is
programmed are not changed.
EXAMPLE
G1O P16 x32.5 wO.05 ;
-r T7————

Z- axis value
LContents of tool offset No. 16
is changed
The above format is used to make offset
value tapes,
and to store the values in
Offset M-emery at once.
The tape format is as follows .
