Limitations of deformation detection
Deformations that protrude into the object and are shaded by edges cannot be detected by the system
as shown in the following figure. In this case Xnet < Xmin.
Figure 11: Object with inward bulge
If, as shown in Figure 12, the smallest enclosing perimeter (blue) is much smaller than the object
perimeter (red), a deformation cannot be distinguished from the rest of the object structure.
In this case, after the measurement, the system outputs the status NOK and the length, width and
height of the smallest enveloping box (including all projections of the object).

4.4 Minimum distance between two objects
Formula for calculating the minimum distance D
min
between two objects:
D
min
= 12 x [Fix resolution of CML 730: 5mm] + [Cycle time: 50ms] x [Conveying speed v in m/s]
Sample calculation with conveying speed v = 0.8 m/s
D
min
= 12 x 5mm + 50ms x
∙0.8 m/s = 100mm
4.5 Maximum conveying speed
NOTICE
Be sure to observe the maximum conveying speed!
If the maximum conveying speed is exceeded, the system may not provide reliable
measurement results.
