Inspection During Production

Inspections need to be performed during production and during assembly. These inspections are tightly coupled to the work flow and work procedures. Another factor is the quantity to be produced since any software must support single part as well as serial production. The iQ-FEP module provides support for the complete range of required inspections including sampling inspections, single part inspections, inspections during assembly, inspections of charges, 100% inspections, product audits and final part inspections.

Workflow

As any other modules related to inspections iQ-FEP is based on an inspection plan previously created in the iQ-PLAN module. The inspection plan can be created manually or generated from CAD drawings (see iQ-CAD-Interface). It is possible to specify the sampling size (100%, static or dynamic) for the single characteristics (variable or attributive) under consideration of drawings, measuring and test equipment and inspection locations. A specialty of iQ-FEP is its tight connection to the work plan allowing the definition of a specific pre-machining measure for any characteristic and work procedure. The inspection itself is prepared by generating an inspection order from the plan either manually or triggered from the ERP system.

The inspector can use different views for an optimal support in using the inspection environment for the upcoming inspections. By supporting different measuring devices or machines iQ-FEP provides the highest efficiency. Using the Watchdog, problems during production can be reported to email recipients or to the Quality Control Station (iQ-QLEIT). Usage decisions can be made, and it is possible to generate evaluations (including original data chart, x bar, histograms etc.).

Important Features at a Glance

Inspection planning

Inspection planning (see iQ-PLAN) is the process of defining the parameters for the inspections. In inspections during production it is typically used for:

Order generation

Generation a production order can be initiated manually or be triggered from the ERP system (see iT-INTERFACE). Depending on the use case the following parameters require consideration:

Inspection

The general features of any modules related to inspections are covered in the module description of iQ-PAUF. However, there are some specialties for inspections during production:

(Automatic) input of measuring data

Measuring data can be received from standard or complex measuring devices (such as multiple measuring equipment), from a measuring box (Steinwald, IBR or BOBE), or via a serial interface (RS232). Other measuring data can be imported using the import filter. Very huge numbers of measuring values, for example from third-party systems, could also be received in the background (optionally using a discriminator) by the additional module iQ-MESSDAT.

Cumulative reject charts

Cumulative reject charts can be imported into the system either automatically or by scanning a printout (see iQ-BELEG). If there are defects they could be specified per characteristic by selecting from defect groups (mode, location and cause) that have been defined when creating the inspection plan.

Monitoring

During recording of data it is possible to monitor upper and lower limit violations of original value, s, cpk, p etc. using the Watchdog and send them by mail or pass them to the Quality Control Station (see iQ-QLEIT). Defects can be assigned to quality projects using the Quality Control Station where it is also possible to initiate corrective actions.

Usage decisions

(Partly) usage decisions can be made during production monitoring. If a usage decision is to be made or not is specified on the material level. The decision consists of:

The history of the production quality for material disposition and inspection results (see iQ-FERTBEW) is based on the usage decisions.

Evaluations/reports

Capability analyses cmk

To perform machine capability examinations it is possible to record and evaluate separate measuring data. The calculation of cm and cmk is only done in case of a normal distribution. If the values are not distributed normally the calculation is passed to qs-STAT.

qs-STAT interface

Advanced evaluations are supported by providing an interface to qs-STAT. The data selection is performed in iQ-BASIS is then directly passed to qs-STAT for further processing.
