By installing the touch sensor and by manually making the tool contact
the touch sensor, it is possible to set the offset amount of that tool
automatically in the tool offset amount memory. It is also possible to set
the work coordinate system shift amount automatically.
The touch sensor has contact faces in two directions along each axis, and
outputs the following four signals by contact detection. These signals are
input to CNC as tool compensation value writing signals.
The contact faces are to be selected according to the shape of the nose of
the tool to be measured.
+MIT1 (+MITX) :
Contact the (+) contact face of the X axis
(Contact in the X+ direction)
–MIT1 (–MITX) :
Contact the (–) contact face of the X axis
(Contact in the X- direction)
+MIT2 (+MITZ) :
Contact the (+) contact face of the Z axis
(Contact in the Z+ direction)
–MIT2 (–MITZ) :
Contact the (–) contact face of the Z axis
(Contact in the Z- direction)
