2.8.19.2.2 How to set the tool nose R data
memory
The tool nose R data memory is set through the
offset screen (Fig. 2.35).
--
a
(a) Select the “ OFS “ function.
(b) Select the corresponding tool offset memory
from TO1 to T49.
tool nose R data is “O, 8 mm” ,
2.8. 19.2.3 G41, G42 command
The offset direction of the current cutting is
commanded by the G41, G42 commands (X plus
specification ).

T code command
The T code number ( 4 digits) determines the
coordinate system, wear off set, and tool nose R.
For details, refer to par. 2,6.5 ‘!New coordinate

(1) Approach GOO + GO1 or relief GO1 + GOO
(a) When the cutting command move axis direction
is larger than 45° against the Z-axis
(1 X/21 >
I ZI ), a projected vector (wall)
parallel to the Z-axis is assumed, to calculate
the compensation with the cutting move axis.
The machine moves toward this calculated
position.
(b) When the cutting command move axis direction
is smaller than 45° against the Z-axis
( lX/21 < = I ZI ) , a projected vector (wall)
parallel to the Z- axis is assumed, to
calculate the compensation with the cutting
move axis.
The machine moves toward this calculated
position.

2.8.19.3 Offset Calculation of Automatic Nose R
Compensation Approach and Relief
The automatic nose R compensation function has
been improved from the nose R compensation
function of the conventional YASNAC LX3.
2.8. 19.3.1 The GOO + GOO block is not
compensated.
In short, positioning alone is
performed.
2.8. 19.3.2 Compensation is performed for
approach GOO + GO1 (G02, G03) by setting a
prolected vector (wall) on the tool to prevent
excess infeed or shock, as follows.
Compensation is performed for relief GO1
(G02. G03) + GOO, by setting a projected vector
(wall) to prevent insufficient cut, as follows.
