Quality control for data
cable production
The Centerview 8000 from Sikora is designed to deliver
non-contact continuous measurements of 8-point eccentricity,
4-axis diameter and 8-point ovality during the production of
data cables. The online repeatability and accuracy of these
non-contact measurements provide optimum control and
productivity on today’s production lines at all line speeds.
A feature of the Centerview is the automatic positioning of the
gauge head to the cable position. With this design, guide rollers
are not required to achieve precise single measuring values,
even at the micron level.
Centerview 8000 records the single measuring values with
highest precision. These are displayed at 4-points (diameter)
and 8-points (eccentricity, ovality) on the processor system
Ecocontrol 600, 1000 or 2000. Instantly, the operator has clear
information about eccentricity values that can be used for
control or crosshead adjustments.
Centerview 8000 is available as a stand-alone gauge head with
direct connection to a control system or a data collection system
for SPC (statistical process control). It can be combined with
the processor system, Ecocontrol, for constant accurate online
measurement and control.
The cloud diagram provides an additional way to present
the measuring values of the ongoing measurement at the
Ecocontrol. It provides information on distribution of short-term
variation of eccentricity in graphical form. Each dot corresponds
to one single measuring value of the eccentricity in relation to
the amount and angle. The extension of the cloud diagram is
the indicator for the standard deviation of the eccentricity.
The display of the single eccentricity values in the cloud diagram
shows the operator what eccentricity values remain and what
fluctuation the product has, even after a perfect centring.
This visualisation of the single values provides an option for
the operator to take appropriate measures to minimise the
eccentricity.
