With Q-DAS' popular procella SPC software, measurement and inspection data can be quickly acquired either by manual input or on-line, via the serial interface of the measuring device. On-line visualization of the acquired data enables timely detection of trends and out-of-control conditions.
The user is therefore in an excellent position to initiate timely corrective action. Data are checked against individually defined alarm thresholds (violation of tolerance or control limits) as soon as they are collected. If an alarm occurs, the operator is required to acknowledge the alarm. Actions taken, events and causes can be documented.
The user can be required to enter supplementary data (cavity, machine, batch, etc.), which allows for traceability throughout, and for object-related analysis of relevant information.
In advanced enterprise solutions, integration via an IDI interface connection with SAP/R3 QM makes it possible to load inspection lots generated by SAP into procella for industrial data acquisition. Once the examination is completed, the acquired data are transferred back to SAP. In this way, users can benefit both from the flexibility of procella in terms of data acquisition and on-line visualization, and the advantages of a centralized umbrella system such as SAP.
In traditional manufacturing Production to make the product and the Quality Department inspect it. After-the-event inspection is expensive and wasteful because:
The product has already been made
Costly re-work is not always possible
It is much more cost effective to avoid waste by monitoring and analysing the process during manufacture. This is the basis of statistical process governor (SPC).
you can measure process quality in a quantitative way and establish the process capability of your manufacturing operations. This is a measure of the extent of the variation of a key feature of a product ie. weight, length, thickness and so on, compared with the specification limits. It tells you how well you can expect a machine or a plant to perform.
Wonderware's QI Analyst 8.0 real-time SPC software can give your industrial production team the quality information they need to adjust process parameters on the fly, which can decrease costs and improve product quality. Traditional off-line SPC systems use historical process data and don%u2019t allow real-time corrections of process excursions.
QI Analyst software is an important part of Wonderware's software solutions for Production and Performance Management. Its comprehensive, real-time SPC monitoring keep Wonderware customers informed regarding developing product-quality problems.
