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
Selection of the touch probe used
TYPE
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
In SET_UP you define how far from the defined (or calculated)
SET_UP
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
To increase measuring accuracy, you can use TRACK = ON to have
TRACK
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
