As the central database for production, with its own data management for production- and process related parameters, complementary to master data transferred from SAP/ERP, the CAO system prepares the ground both for the standardization of process parameters, as for the process itself. The direct connection of machines in the system allows for the automatic transfer of job data and process parameters directly into the machine controllers, and furthermore for a far-reaching process control, in which setup tools and materials are identified with their batch and inventory numbers, and process and quality data are electronically recorded and instantly evaluated. This way, wrong assembly can be widely avoided, quality assurance measures can be integrated into the process itself, and the collection of data for process analysis by the management on one side, and for traceability and process documentation on the other side, is done automatically and consistenly at the source.
The recent expansions in the CAO are again all about standardization, secure processes and further improvements in transparency and traceability. Thus, with the much expanded and improved Tools Management and with the implementation of measures for Statistical Process Control (electronic control cards and automatic calculation of process capability indices Cpk), the system continues on the path to "zero-defect production".
Since the integration of the micrograph-process into CAO production control, all processes in the cutting area are now being mapped in one homogeneous system enabling comprehensive and exclusive quality documentation in the CAO Production Archive. With respect to traceability in the cutting area, the archive has become the central source of information, answering also to the needs of material batch tracking.
The introduction of the CAO system in several production sites creates a company-wide standard, with big saving potentials and a large increase in flexibility, that also provides a means to objectively compare the different sites.
The additional introduction of a central data server for the company-wide specification of process parameters (eg crimp parameters) and company-wide management of key resources (such as machines and tools) is the yet another step towards global quality standards and process control. Also included in the package is a central management report that has been implemented as a web application. A series of automated reports reveal the most important figures and developments of selected production sites and present them graphically. In addition, an also web-based plant image informs about the current states in production, so that management is informed at all times both for long term analysis and when quick action is required.
The CAO system is scalable and can be obtained for 2 to 200 cutting machines per plant. At the Productronica 2011, DiIT will present a new CAO version for small and medium companies that can be installed with a few mouse clicks by the customer himself. In addition, the expansion of the CAO to the pre-assembly area will be an important issue at the upcoming fair.
