Probing technique
Probing technique refers to the method of moving CMM
axes and entering point data with a touch probe. Good
probing technique includes the following:
• Approach the surface at a 90° angle
• Approach the surface without direction changes
from a distance of at least 5 mm
• Do not drag the probe across the surface
• Do not probe on a sharp edge or drop the probe off
an edge of the part
Auto change/teach function
Star and indexable probe tips or positions can be changed or qualified at the CMM work surface without
touching front panel controls when the Auto change/teach function is enabled in the Probe setup screen as
described in Chapter 10: Setup.
To change or qualify a new star probe tip or indexable probe position:
1 Touch the qualification sphere once with the current (qualified) tip.
2 Touch the qualification sphere a second time with the new star probe tip or the new indexable probe
position. If the new tip or position was previously qualified, the QC-330 will acknowledge the change and
continue gathering feature data. If the new tip or position was not previously qualified, measurements will
be temporarily suspended and a probe qualification will be initiated. When the qualification is complete,
the measurements will be resumed.
