Reference data
With the help of the reference data, the quality features can be defined for
individual workpieces.
To be able to define the quality requirements for the individual workpieces,
you first have to record the reference data.
Set the "Output Diagram" parameter to "Continuous" to display all force
curves as a group of curves.
Produce a workpiece and check whether it meets the quality
requirements.
Repeat the production process and the check until a Not O.K. part is
produced. When compared to the recorded curves, this Not O.K. part
exhibits an outlier in at least one place.
