- Conditions for Making a Path Interference Check
A path interference check is made when conditions listed below are
satisfied.
(1) Common conditions
• Parameter IFE (No. 8140#4) for enabling the path interference
check function is set to 0.
• The X- and Z-axes of the three basic axes are set for parameter No.
1022 for individual paths for which a path interference check is to
be made.
• After power is turned on, reference point return operation is
completed with all axes. (When an absolute-position detector is
used, the matching between a machine position and
absolute-position detector position must be completed.)
• Offset numbers other than 0 are specified using T codes for tool
posts on the paths for which a path interference check is made.
• Values are input in either one or both of the areas of the tool shape
data corresponding to the specified tool number and the
relationships among the values are X > I and Z < K.
• When manual mode is used, parameter IFM (No. 8140#3) for
enabling the tool post interference check function in manual mode
is set to 1.
(2) Conditions for a multipath interference check
A multipath interference check is made when the conditions below as
well as the common conditions are satisfied:
• Bit 7 (IFP) of parameter No. 8140 for enabling the multipath
interference check function is set to 1.
• The path associated with each signal of Gn406 and Gn407 for each
path exists.
(3) When the interference check conditions are satisfied
When all conditions for making a path interference check are satisfied,
the path-interference-check-in-progress signal is output to the PMC.
WARNING
To make a path interference check, the tool number
for which tool shape data is input must agree with
the programmed tool number. An interference
check cannot be made correctly if the tool is
selected by manual operation or if no tool select
command is specified at power-on.
