Cycle parameters
U Exact calibration sphere radius Q407: Enter the
exact radius of the calibrating ball used. Input range:
0.0001 to 99.9999
U Setup clearance Q320 (incremental): Additional
distance between measuring point and ball tip. Q320
is added to MP6140. Input range 0 to 99999.9999,
alternatively PREDEF
U Retraction height Q408 (absolute): Input range
0.0001 to 99999.9999
„ Input 0:
Do not move to any retraction height. The TNC
moves to the next measuring position in the axis to
be measured. Not allowed for Hirth axes! The TNC
moves to the first measuring position in the series
A, the B, the then C
„ Input >0:
Retraction height in the untilted workpiece
coordinate system to which the TNC positions
before a rotary axis positioning in the spindle axis.
Also, the TNC moves the touch probe in the
working plane to the datum. The probe monitoring
is not active in this mode. Define the positioning
velocity in parameter Q253.
U Feed rate for pre-positioning Q253: Traversing
speed of the tool during positioning in mm/min. Input
range: 0.0001 to 99999.9999; alternatively FMAX,
FAUTO
, PREDEF.
U Reference angle Q380 (absolute): Reference angle
(basic rotation) for measuring the measuring points in
the active workpiece coordinate system. Defining a
reference angle can considerably enlarge the
measuring range of an axis. Input range: 0 to
360.0000
