- Canceling grinding wheel wear compensation
When G40 and D0 are specified at the same time, the compensation
vector is canceled, movement due to the cancellation takes place, then
grinding wheel wear compensation is canceled.
When D0 has been canceled, specifying G40 cancels grinding wheel
wear compensation without causing movement due to the
compensation vector cancellation. This is because the compensation
vector has already been canceled by the D0 command.
- Grinding wheel wear compensation status
G code D code Mode and its meaning
Other than 0 Grinding wheel wear compensation mode
(A compensation vector is created.)
G41
0 Compensation vector cancel mode
(No compensation vector is created.)
Other than 0 Compensation vector maintenance mode
(A compensation vector is maintained.)
G40
0 Grinding wheel wear compensation cancel
mode
(Grinding wheel wear compensation is
canceled.)
- Compensation plane
In grinding wheel wear compensation mode or compensation vector
maintenance mode, a compensation vector is always created for the
axes on the compensation plane determined by parameter Nos. 6056
and 6057.
If an axis on the compensation plane is changed in this mode, alarm
PS619 is issued in a block for obtaining the movement end position.
- Compensation vector
A compensation vector is created only on the plane (compensation
plane) of the axes (compensation axes) set in parameter Nos. 6056 and
6057.
On an extension of a straight line starting from the compensation center
and directed toward the command end position, a compensation vector
is created, where the length of the vector equals the offset value
specified by the offset number in a D code. (See Fig. 10.4.12 (a).)
If the offset value is negative, a compensation vector whose direction is
from the compensation center toward the command end position is
added to the command end position. (See Fig. 10.4.12(b).)
If the offset value is positive, a compensation vector whose direction is
from the command end position toward the compensation center is
added to the command end position. (See Fig. 10.4.12(c).)
The direction of the compensation vector can be changed by bit 3
(WCD) of parameter No. 6008.
