Travel To Fixed Stop (Fxs, Fxst, Fxsw) - Siemens SINUMERIK 840DE Programming Manual

Example
The tool change location is a fixed point, which is defined in the machine data.
This point can be approached in any NC program with G75.
N10 G75 FP=2 X1=0 Y1=0 Z1=0

Travel to fixed stop (FXS, FXST, FXSW)

Function
The "travel to fixed stop" (FXS = Fixed Stop) function can be used to build defined forces for
clamping workpieces, such as those required for tailstocks, quills and grippers. The function
can also be used for the approach of mechanical reference points.
With sufficiently reduced torque, it is also possible to perform simple measurement
operations without connecting a probe. The "travel to fixed stop" function can be
implemented for axes as well as for spindles with axis-traversing capability.
