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
 Traversing to clearance height
Q301: Definition of
how the touch probe is to move between the
measuring points:
0 : Move at measuring height between measuring
points
1 : Move at clearance height between measuring
points
Alternatively PREDEF
 No. of probe points in plane (4/3)
Q423: Specify
whether the TNC should measure the calibration
sphere in the plane with 4 or 3 probing points. Three
probing points increase the measuring speed:
4 : Use 4 measuring points (standard setting)
3 : Use 3 measuring points
 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
 Calibrate length (0/1)
Q433: Define whether the
TNC is to calibrate the touch probe length after radius
calibration, as well:
0: Do not calibrate touch probe length
1: Calibrate touch probe length
 Datum for length Q434 (absolute): Coordinate of the
calibration sphere center. The definition is only
required if length calibration is to be carried out. Input
range -99999.9999 to 99999.9999
