2.6 Measuring Workpieces with a
3-D Touch Probe
Introduction
You can also use the touch probe in the Manual and Electronic
Handwheel operating modes to make simple measurements on the
workpiece. With a 3-D touch probe you can determine:
n
position coordinates, and from them,
n dimensions and angles on the workpiece.
To find the coordinate of a position on an aligned
workpiece:
U U U U Select the probing function by pressing the PROBING
POS soft key.
U U U U Move the touch probe to a starting position near the
touch point.
U U U U Select the probe direction and axis of the coordinate.
Use the corresponding soft keys for selection.
U U U U 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: See “Corner as datum—
without using points that were already probed for a basic rotation,”
page 21. The TNC displays the coordinates of the probed corner as
datum.
