2.5 Measuring Workpieces with a 3-D Touch Probe

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.
