WT: Compens. no.1, measd. edge
T: Tool at turret position T to compensate the difference to
the nominal value
G149: Additive compensation D9xx to correct the difference
to the nominal value (only possible with compensation type
R = 1)
AT: Compens. no.2, measd. edge
T: Tool at turret position T to compensate the difference to
the nominal value
G149: Additive compensation D9xx to correct the difference
to the nominal value (only possible with compensation type
R = 1)
FP: Maximum perm. correction
WE: Max. deviation – probe twice and monitor the dispersion
of the measured values
F: Measuring feed – feed rate for probing (if nothing is entered,
the measuring feed rate from the touch probe table is used)
If the entered measuring feed rate F is higher than the one in
the touch probe table, the feed rate is reduced to the value from
the touch probe table.
Q: Tool orientation (machine-dependent)
Orient the touch probe in the programmed probing direction
before each probing operation.
P: PRINT outputs
0: OFF – do not display measuring results
1: ON – display measuring results on the screen
H: INPUT instead of measure
0: Standard – obtain measured values by probing
1: PC test – simulate touch probe cycle on the programming
station
AN: Log no. – save measurement results in the
TNC:\table\messpro.mep table (line numbers 0-99)
The table can be expanded if necessary.
The cycle computes the Compens. no.1, measd. edge
WT from the result of the first measurement and the
Compens. no.2, measd. edge AT from the result of the
second measurement.
Example: G776 Two-point measurement for tool compensation
