production data is ascertained on the basis of this information for an
evaluation period which can be freely defined by the operator.
The production status illustrated in Fig. 4.4.48 offers a survey of the
most important data from all the shifts of a production day. In addition,
the pre-processed data can be exported in a standard data format in
order to give the user the chance to execute his or her own evaluation.
Data acquisition and processing for draw cushions
The acquisition and processing system for measured values for the draw
cushion, known as the Cushion Monitoring System (CMS), permits the
observation of the drawing process. In addition, this provides support
for repair personnel in terms of malfunction diagnostics and also when
resuming production after a component failure. All the relevant set values,
control signals and process variables (actual values) for pre-acceleration
and for the actual drawing process are monitored and stored, for
example
