touch probe data
Abbr. Inputs Dialog
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
Selection of the touch probe?
CAL_OF1
Offset of the touch probe axis to the spindle axis in the
principal axis
TS center misalignmt. ref. axis?
[mm]
CAL_OF2
Offset of the touch probe axis to the spindle axis in the
minor axis
TS center misalignmt. aux. axis?
[mm]
CAL_ANG
Prior to calibrating or probing the control aligns the touch
probe with the spindle angle (if spindle orientation is
possible)
Spindle angle for calibration?
F
Feed rate at which the control will probe the workpiece
Probing feed rate? [mm/min]
FMAX
Feed rate at which the touch probe is pre-positioning and
is positioned between the measuring points
Rapid traverse in probing cycle?
[mm/min]
DIST
If the stylus is not coordinated within this defined value,
the control will issue an error message.
Maximum measuring range?
[mm]
SET_UP In SET_UP you define how far from the defined or
calculated touch point the control 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.
Set-up clearance? [mm]
F_PREPOS
Defining speed with pre-positioning:
Pre-positioning with speed from FMAX: FMAX_PROBE
Pre-positioning with machine rapid traverse:
FMAX_MACHINE
Pre-position at rapid? ENT/
NOENT
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
Probe oriented? Yes=ENT/
No=NOENT
