1) Select linear feed. (R961)
Set R961 to 1.
2), 3) Specify the approach direction. (R962 to R969)
Specify the X and Y components (Ix, Iy) of a unit vector (+cosθ,
+sinθ ) or (–cosθ , –sinθ ), which is parallel to perpendicular op,
with four bytes. The setting value is multiplied by 2
30
.
R962 to R965 = Ix 2
30
R966 to R969 = Iy 2
30
The tool moves in the direction indicated with this vector, when
the approach handle is rotated in the forward direction.
4) Specify the length (P) of perpendicular op (line segment
beginning at origin o and perpendicular to the given line) using
4 bytes. (R970 to R973)
Length P must satisfy the following equation:
P= +
op
→
, where +
op
→
for (+cosθ , +sinθ) or –
op
→
for (–cosθ,
–sinθ)
The unit of P is the least input increment. (Example: For IS–B
with metric input, the unit of P is 0.001 mm.)
R970 to R973 = P
5) Specify the cutting direction. (R974)
Specify the direction of travel, corresponding to the forward
rotation of the guidance handle, with R974. The meaning of the
setting is as follows:
0: Direction towards +90° from the approach direction
1: Direction towards –90° from the approach direction
6) Specify whether to enable the limit function. (Bit 7 of R975)
To disable the limit function, reset bit 7 of R975 to 0.
To enable the limit function, set bit 7 of R975 to 1.
When the limit function is enabled, it sets up an area which the
tool is not allowed to enter. The area is delimited with a specified
line. When you attempt to bring the tool into the prohibited area,
using manual handle or jog feed, the tool decelerates and stops.
The prohibited area is set up as shown below, according to the
setting of the approach direction (R962 to R965, R966 to R969).
