Abstract:
In the field of machine tools, a continuous trend towards automated and networked production systems is recognizable in order to cope with the autonomous and self-organized systems promoted within Industry 4.0. For this purpose, large quantities of partially unstructured data exist within the machine-internal control system. The informational value of this data can be enhanced by suitable algorithms and utilized for multivalent applications. In addition to the information of the computerized numerical control such as feed rate or axis positions the drive systems of machine tools can be consulted. The major advantage of the drive internal information is due to the high temporal resolution of the available data, which is significantly above the interpolation cycle of modern CNC (e.g. Siemens 840D sl). However, a major obstacle is the access to this information, since most of the parameters are processed directly in the drive internal control loops and therefore not transmitted to the s
uperordinate control. Within the paper, a practical solution for the automatic acquisition and processing of drive data is presented. Based on a machine internal data management system in combination with an industrial embedded system the extraction and aggregation of control loop data in the sense of so-called Smart Data Services is realized.
