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): Define
an 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)?: Definition of
whether TNC should create a measuring log:
0: Create no measuring log
1: Create measuring log: The TNC will save the
log file TCHPR426.TXT
TNC:\.
2: Interrupt the program run and display the
measuring log on the TNC screen. Resume
program run with NC Start.
