Basic test bench PS40

 

The basic test bench PS40 consists of a cylindrical grinding machine S41 equipped with measuring technology from Fritz Studer AG.

The focus is on researching the potential of the topic "Industry 4.0 in grinding technology". The main focus is on the implementation of an assistance system for the machine operator, which should provide recommendations for process optimization and setup. As a customer-specific solution, the S41 already has a force measurement platform integrated in the workpiece spindle head for online determination of the grinding force in the process, as well as a force measurement platform under the dressing spindle for recording the dressing force. In addition, the machine has an integrated cooling lubricant pressure and temperature measuring unit. In line with Industry 4.0, the machine will be equipped with additional measuring sensors in future projects. By generating a range of production data (data mining) and analyzing this big data using evaluation algorithms (data analysis), previously unknown correlations between input and output variables are to be created and made available to the user visually (data utilization).

The investigations on the PS40 basic test bench serve primarily to optimize the process parameters, such as cutting speed, feed rate, infeed, and to investigate their influence on workpiece quality. In addition, analyses regarding tool wear and the testing of measures to reduce tool wear are carried out. In addition, basic investigations are carried out on the conditioning of grinding tools, such as dressing parameters, dressing tools or similar. In addition, the interaction of operating materials, cooling lubricant, tool material and workpiece material is investigated on the test bench in basic experiments, for example the effect of unbalance-induced vibrations on the process result.
