2.5 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. Numerous programmable probing cycles are available for
more complex measuring tasks (see “Automatic Workpiece
Measurement” on page 105). 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:
8 Select the probe function by pressing the PROBING
POS soft key.
8 Move the touch probe to a starting position near the
touch point.
8 Select the probe direction and axis of the coordinate.
Use the corresponding soft keys for selection.
8 To probe the workpiece, press the machine START
button.
The TNC shows the coordinates of the touch point as reference point.
Finding the coordinates of a corner in the
working plane
Find the coordinates of the corner point: See “Corner as datum,” page
35. The TNC displays the coordinates of the probed corner as
reference point.
