Example 2)
Start point
End point
The tool is stopped at point (a) stipulated
by stored stroke check 2 or 3.
Immediately upon movement commencing
from the start point, the tool is stopped, since
the end point is determined to be within the
prohibited zone
a
Prohibited area defined by
stored stroke check 2 or 3
Prohibited area defined by
stored stroke check 2 or 3
End point
Start point
When a stroke limit check before move is performed, NPC (parameter No.
1301#2) is used to determine whether to check the moves performed by
G31 (skip) or G37 (automatic tool length measurment).
If machine lock is applied at the start of movement, no stroke limit check
made before movement is performed.
When stored stroke check 2 is disabled (G23 mode), no check is made to
determine whether the tool enters the prohibited area defined by stored
stroke check 2.
When a program is restarted, an alarm is issued if the restart position is
within a prohibited area.
When the execution of a block is restarted after manual intervention
following a feed hold stop, no alarm is issued even though the end point
following a manual intervention is within a prohibited area.
If a block consisting of multiple operations (such as a canned cycle and
exponential interpolation (M series only) is executed, an alarm is issued
at the start point of any operation whose end point falls within a prohibited
area.
