12.3 Measuring Workpieces with a
3-D Touch Probe
The TNC 426 and TNC 430 offer a number of convenient
measuring cycles that enable you to measure workpiece
dimensions. These cycles are described in a separate
User's Manual. Contact HEIDENHAIN if you would like a
copy of the Touch Probe Cycle Manual.
With a 3-D touch probe you can determine:
■ position coordinates, and from them,
■ dimensions and angles on the workpiece.
To find the coordinate of a position on an aligned
workpiece:
ú To select the touch probe function: Press the
PROBING POS soft key
ú Move the touch probe to a starting position near the
touch point.
ú Select the probe direction and axis of the coordinate.
Use the corresponding soft keys for selection.
ú To probe the workpiece, press the machine START
button.
The TNC shows the coordinates of the touch point as datum.
Finding the coordinates of a corner in the working
plane
Find the coordinates of the corner point as described under “Cor-
ner as datum.” The TNC displays the coordinates of the probed
corner as datum.
