Establishing The Measurement Reference; Leveling The Part (Optional) - HEIDENHAIN ND 1300 Operating Instructions Manual

NOTE
When edge detection is used, the edge detection must be calibrated, and the optical
system must be clean. The edge calibration is described in Chapter 5: Probes.

Establishing the measurement reference

A reliable measurement reference must be established before part features can be probed and measured.
This reference will be created by the user and ensures a level part surface, precise part alignment and a
coordinate origin or datum zero. Reference features are presented in the feature list in blue, other features
are presented in black.

Leveling the part (optional)

When the surface plane of the part is not orthogonal to the measurement axis, small cosine errors can be
generated during the measuring process. These errors can be minimized or eliminated by leveling the
part.
CAUTION
Leveling is optional in most well-maintained systems. Additionally, if the depth of
field of the lens system is not much less than the level error, no benefit can be gained
from leveling the part.
To level the part:
1 Touch the Measure Skew icon and then touch the Measure Level icon.
