WARNING
When an alarm is raised, the CNC system and machine
system stop with some delay in time.
So an actual stop position can be closer to the other tool
post beyond an interference forbidden position specified
using tool shape data. So, for safety, tool shape data a little
larger than the actual shape should be set. The extra
distance, L, required for this purpose is calculated form a
rapid traverse feedrate as follows
For example, when a rapid traverse feedrate of 15 m/min is
used, L=2mm.
L= (Rapid traverse feedrate) ×
1
7500
CAUTION
When parameters and interface forbidden areas (Section
23.3.2) are set to use the interference check function, be
sure to check that correct interference forbidden areas are
set. For this purpose, set manual mode, and cause the tool
posts to interfere with each other in various directions.
