Cycle parameters
U
Exact calibration sphere radius
Q407: Enter the
exact radius of the calibration sphere used. Input 
range 0.0001 to 99.9999
U
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
U
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
U
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. 
3 probing points increase the measuring speed:
4: Use 4 measuring points (standard setting) 
3: Use 3 measuring points
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
U
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
U
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
