Measuring workpieces with a 3-D touch probe
You can also use the touch probe in the Manual Operation and
El. Handwheel operating modes to make simple measurements
on the workpiece. Numerous programmable probe cycles are
available for complex measuring tasks (see User's Manual for
Cycles, Chapter 16, Checking workpieces automatically). With a 3-D
touch probe you can determine:
Position coordinates, and from them,
Dimensions and angles on the workpiece
Finding the coordinates of a position on an aligned workpiece
Select the probing function: Press the PROBING
POS soft key
Move the touch probe to a position near the touch
point
Select the probe direction and axis of the
coordinate. Use the corresponding soft keys for
selection
Start the probing procedure: 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 415. The TNC displays the coordinates of the probed corner
as reference point.
