Caution
- Items common to both 2-path interference and multi-path interference checks
NOTE
1 If an alarm occurs due to a path interference check, first switch to manual mode,
manually retract the tool post of the path in which the alarm occurred to a position
without interference, then perform a reset to cancel the alarm on the control unit.
By manually retracting the tool post, the TIALM signal will become "0" at the point
when the tool post associated with the interference is judged not to interfere. (This
can be used as a guideline: If, after a tool post has interfered, retracting it
manually, you have only to retract it until the TIALM signal becomes "0".)
2 If an alarm occurs due to a path interference check, the axis and direction of
movement that were assumed at that time will be stored, so that the tool can no
longer be moved in the stored direction along the stored axis until the alarm on the
control unit is canceled with a reset. (Any start that will result in further
interference will be prohibited.)
3 If an interference alarm occurs, the tool post will stop before the interference
position if parameter BFA (No.1300#7) is set to 1.
If this parameter is set to 0, the CNC and the machine system will stop somewhat
later than the correct time, the positions at which they actually stop will be closer to
the other tool post that the interference position specified in tool figure data. For
safety, therefore, the tool figure data must be somewhat larger than necessary.
The excess distance L may be calculated from the rapid traverse rate.
L = (Rapid traverse rate) x 1/7500
If, for example, the rapid traverse rate is 15 m/min, the figure data must be larger
by about 2 mm.
