NOTE Tool number
The tool geometry data must be set for each tool number.
The tool number here refers to the offset number. When
both tool geometry offset and tool wear offset are used, the
tool number corresponds to the wear offset number. To use
two or more offset numbers for the same tool, the same data
for the tool must be set two or more times in the tool
geometry data.
A tool post interference check is made when all conditions listed below
are satisfied.

check function is set to 0.
(2)After power is turned on, reference point return operation is completed
with all axes (X1,Z1, X2, Z2).(When an absolute–position detector is
used, the matching between a machine position and absolute–position
detector position must be completed.)
(3)Offset numbers other than 0 are specified using T codes for two tool
posts.
(4)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.
