Touch probe data

Abbr. Inputs
NO
Number of the touch probe: Enter this number in the
tool table (column: TP_NO) under the appropriate tool
number
TYPE
Selection of the touch probe used
CAL_OF1
Offset of the touch probe axis to the spindle axis for the
reference axis
CAL_OF2
Offset of the touch probe axis to the spindle axis for the
minor axis
CAL_ANG
The TNC orients the touch probe to the orientation angle
before calibration or probing (if orientation is possible)
F
Feed rate at which the TNC is to probe the workpiece
FMAX
Feed rate at which the touch probe pre-positions, or is
positioned between the measuring points
DIST
If the stylus is not deflected within the defined path, the
TNC outputs an error message
SET_UP In SET_UP you define how far from the defined (or
calculated) touch point the TNC is to pre-position the
touch probe. The smaller the value you enter, the more
exactly you must define the touch point position. In
many touch probe cycles you can also define a set-
up clearance that is added to the SET_UP machine
parameter.
F_PREPOS
Defining speed with pre-positioning:
Pre-positioning with speed from FMAX: FMAX_PROBE
Pre-positioning with machine rapid traverse:
FMAX_MACHINE
TRACK To increase measuring accuracy, you can use TRACK
= ON to have an infrared touch probe oriented in the
programmed probe direction before every probe
process. In this way the stylus is always deflected in the
same direction:
ON: Perform spindle tracking
OFF: Do not perform spindle tracking
