Fixed Feedrate Values - Siemens SINUMERIK 840D sl Function Manual

Example
Internal grinding of a conical ring, where the actual diameter is determined using calipers and,
depending on the limits, the feedrate value required for roughing, finishing or fine finishing is
activated. The position of the calipers also provides the end position. Thus, the block end
criterion is determined not only by the programmed axis position of the infeed axis but also by
the calipers.

Fixed feedrate values

Function
The "Fixed feedrate values" function can be used to activate fixed feedrates (max. four) defined
via the machine data instead of the programmed feedrate or the configured JOG velocities.
The function is available in AUTOMATIC and JOG mode.
Behavior in AUTOMATIC mode
The contour travels at the activated fixed feedrate, instead of using the programmed feedrate.
