Cycle parameters
 Exact calibration sphere radius
Q407: Enter the
exact radius of the calibration sphere used. Input
range 0.0001 to 99.9999
 Set-up clearance Q320 (incremental): Additional
distance between measuring point and ball tip. Q320
is added to MP6140. Input range 0 to 99999.9999,
alternatively PREDEF
 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
sequence A, then B, 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. Probe monitoring is
not active in this mode. Define the positioning
velocity in parameter Q253.
 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
 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
 Start angle A axis Q411 (absolute): Starting angle in
the A axis at which the first measurement is to be
made. Input range -359.999 to 359.999
 End angle A axis
Q412 (absolute): Ending angle in the
A axis at which the last measurement is to be made.
Input range -359.999 to 359.999
 Angle of incid. A axis
Q413: Angle of incidence in
the A axis at which the other rotary axes are to be
measured. Input range -359.999 to 359.999
 Number meas. points A axis Q414: Number of probe
measurements with which the TNC is to measure the
A axis. If the input value = 0, the TNC does not
measure the respective axis. Input range 0 to 12
 Start angle B axis
Q415 (absolute): Starting angle in
the B axis at which the first measurement is to be
made. Input range -359.999 to 359.999
