Explanations
- Interruption
This function performs interruption only when all the conditions in 1 to
8 are met.
1 During simultaneous manual and automatic operation mode
(including manual interruption using the manual pulse generator)
2 During three-dimensional coordinate conversion (i.e. while
blocks G68 to G69 are being executed.)
3 During cutting mode (i.e. while blocks from a G code for cutting,
such as G01, G02, or G03, to G00 are being executed.)
4 When parking along the feed axis is not enabled (i.e. when PKn
for the feed axis is “0”.)
5 When the machine moves along the three axes selected for three-
dimensional coordinate conversion
6 When the axis for which the function performs interruption is a
master axis under parallel axis control (in this case, no slave axes
are converted).
7 When feed in the tool axis direction or the direction perpendicular
to the tool axis or rotation around the tool tip center is not selected
for the manual operation or the manual interruption using the
manual pulse generator when the ALNGH, RGHTH, and RNDH
input signals are all “0”.
8 While the playback function is not being executed
The result of adding the feedrate in the three-dimensional coordinate
conversion mode is not permitted to exceed the maximum cutting speed
for each axis.
- Manual interruption and the coordinate system
When this function is effective, the current position in the workpiece
coordinate system does not depend on the travel distance specified
during manual interruption using the manual pulse generator. The
current position is therefore not updated even when the manual pulse
generator is rotated. Each current position in the machine coordinate
system and in the relative coordinate system depends on the travel
distance specified during manual interruption. As shown in Fig. 3.6(a),
the travel distance is added along the Z'-axis. The travel distance is
displayed using the X, Y, and Z coordinates of the coordinate system to
be converted. The travel distance specified by this function can be
monitored on the manual overlap screen. The bit 0 (DMK( bit of
parameter 2208 specifies whether the travel distance is displayed on
the manual overlap screen using the coordinate system before (X, Y,
Z)or after (X’, Y’, Z’) three-dimensional coordinate conversion.
