Cycle parameters
Q263 1st measuring point in 1st axis? (absolute):
Coordinate of the first touch point in the reference
axis of the working plane. Input range -99999.9999
to 99999.9999
Q264 1st measuring point in 2nd axis? (absolute):
Coordinate of the first touch point in the minor axis
of the working plane. Input range -99999.9999 to
99999.9999
Q265 2nd measuring point in 1st axis? (absolute):
Coordinate of the second touch point in the
reference axis of the working plane. Input range
-99999.9999 to 99999.9999
Q266 2nd measuring point in 2nd axis? (absolute):
Coordinate of the second touch point in the minor
axis of the working plane. Input range -99999.9999
to 99999.9999
Q272 Measuring axis (1=1st / 2=2nd)?: Axis in the
working plane in which the measurement is to be
made:
1: Reference axis = measuring axis
2: Minor axis = measuring axis
Q261 Measuring height in probe axis? (absolute):
Coordinate of the ball tip center (= touch point) in
the touch probe axis in which the measurement is
to be made. Input range -99999.9999 to 99999.9999
Q320 Set-up clearance? (incremental): Additional
distance between measuring point and ball tip.
Q320 is added to SET_UP in the touch probe table.
Input range 0 to 99999.9999
Q260 Clearance height? (absolute): coordinate in
the touch probe axis at which no collision between
tool and workpiece (fixtures) can occur. Input range
-99999.9999 to 99999.9999
Q311 Nominal length? : Nominal value of the length
to be measured. Input range 0 to 99999.9999
Q288 Maximum limit of size?: Maximum
permissible length. Input range 0 to 99999.9999
Q289 Minimum limit of size?: Minimum
permissible length. Input range 0 to 99999.9999
Q281 Measuring log (0/1/2)?: Define whether the
TNC should create a measuring log:
0: Do not create a measuring log
1: Create a measuring log: The TNC saves the log
file TCHPR426.TXT as standard in the directory
TNC:\.
2: Interrupt program run and output measuring log
to the TNC screen. Resume program run with NC
Start.
