- Cycle operation
When no reference position has been set, operations (A) to (E), below,
are performed automatically to set a reference position.
~~~~~~~~~~~~~~~~~~ ~
Current position
Mechanical
stopper
(A) The tool is moved along a specified axis with a limited torque
until it butts against the mechanical stopper.
- The tool is moved in the direction specified with parameter
ZMIx (No. 1006#5), at the feedrate specified with
parameter No. 7183, at the torque specified with parameter
No. 7186 (until the tool strikes the mechanical stopper).
<~~~~~~~~~~~~~~~~~~~
The direction, feedrate,
and torque are specified
with parameters.
Mechanical
sto
e
(B) After the tool strikes the mechanical stopper, the tool is withdrawn
in the direction opposite to the butting direction, along the axis for
a parameter-set distance.
- The tool is moved in the direction opposite to that specified
with parameter ZMIx (No. 1006#5), at the feedrate
specified with parameter No. 7185, for the distance
specified with parameter No. 7181.

Mechanical
stopper
The direction, feedrate,
distance, and torque are all
specified with parameters.
(C) Operations (D) and (E) are performed from the withdrawal point,
such that the tool is butted against the mechanical stopper at a
constant feedrate in reference position setting.
