FAST PROBING (touch probe cycle 441,
DIN/ISO: G441, FCL 2 function)
Touch probe cycle 441 allows the global setting of different touch
probe parameters (e.g. positioning feed rate) for all subsequently used
touch probe cycles. This makes it easy to optimize the programs so
that reductions in total machining time are achieved.
 Positioning feed rate Q396: Define the feed rate at
which the touch probe is moved to the specified
positions.
 Positioning feed rate=FMAX (0/1) Q397: Define
whether the touch probe is to move at FMAX (rapid
traverse) to the specified positions.
0: Move at feed rate from Q396
1: Move at FMAX
 Angle tracking Q399: Define whether the TNC is to
orient the touch probe before each probing process.
0: Do not orient
1: Orient the spindle before each probing process to
increase the accuracy
 Automatic interruption Q400: Define whether the
TNC is to interrupt program run and display the
measurement results on the screen after a measuring
cycle for automatic workpiece measurement:
0: Never interrupt the program run, not even if the
output of the measurement results on the screen is
selected in the respective probing cycle.
1: Always interrupt program run and display the
measurement results on the screen. To continue the
program run, press the NC Start button
Before programming, note the following
There are no machine movements contained in Cycle 441.
It only sets different probing parameters.
END PGM, M02, M30 resets the global settings of
Cycle 441.
You can activate automatic angle tracking (Cycle
Parameter Q399) only if Machine Parameter 6165=1.
If you change Machine Parameter 6165, you must
recalibrate the touch probe.
