Sophisticated screwing processes in modern screwing equipment are marked with complex parameter settings of the
screwing operations and with their assessment requirements. To gain the potential for improvement, the screwing processes must be handled using a special strategy. To determine the exact parameters and to achieve improved process quality requires development of analysis tools to diagnose the parameter attributes. Increased requirements in the screwing processes demand operator best fit training procedures. A continuous improvement concept for the process control is required to enhance work quality. An information system with a maturity degree for automated screwing processes is developed. To avoid the technical risks, some mechanisms were developed, which automatically extract the process related data and provide it to operator afterwards. By using the information system, information (process and control data) about the parameterization of the screwing control with standardized correlations and a clear tracing of working steps is provided. In this way the running, modification and optimization of the screwing process can be implemented without errors. The developed information system was evaluated on an experimental platform for screwing process in the research laboratory. Thereby, the functionalities of the platform and their components are described and a validation of the developed system is carried out. The development and assembly of the components is presented. Data interrelations are also described in detail. With the developed information system the correct parameterization of the screwing processes with a degree of maturity of the process parameters were achieved. The evaluation of the maturity degree is made with the help of functional properties of the parameters. Consequently, an obvious minimization of the mistakes and a simple screwing process control is achieved.
In this approach a knowledge-based system with a parameters quality assessment for automated
screwing processes is developed. To avoid technical risks, it makes sense to develop methods, which
automatically extract the process related data and provide it to operator afterwards. By using the knowledgebased
system, information (process and control data) about the parameterization of the screwing process control
with standardized correlations and tested process steps is provided. In this way the running, modification and
optimization of the screwing process can be implemented without errors. This system was tested on an
experimental platform for screwing process in the research laboratory. Thereby, the functionalities of the
platform and their components are described and a validation of the developed system is carried out. Data
interrelations between different software components are elaborated in detail. The validation of the system is
done using the screwing process test case. The precision in the parameterization is made with help of functional
properties of parameters. Consequently, an obvious minimization of the parameterization errors and a simple
screwing process control are achieved.
