Using Touch Probe Cycles | Touch probe table

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 in the
principal axis
CAL_OF2
Offset of the touch probe axis to the spindle axis in the
minor axis
CAL_ANG
Prior to calibrating or probing the control aligns the touch
probe with the spindle angle (if spindle orientation is
possible)
F
Feed rate at which the control will probe the workpiece
F can never exceed the value set in machine parameter
maxTouchFeed (No. 122602).
FMAX
Feed rate at which the touch probe is pre-positioning and
is positioned between the measuring points
DIST
If the stylus is not deflected within this defined value, the
control will issue an error message.
SET_UP In SET-UP you define how far from the defined or calcu-
lated 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.
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
SERIAL
You need not make an entry in this column. The TNC
automatically enters the serial number of the touch probe
if the touch probe has an EnDat interface
