Marposs Announces new GEMDS System for Spindle Growth Monitoring

By Marposs Corporation Press Release

Marposs, a provider of measurement, inspection and test technologies, announced on Feb. 26 its new Artis GEMDS system. The system uses data from a non-contact eddy current sensor to provide real-time monitoring of spindle elongation on machine tools due to temperature changes or other causes of displacement. By detecting spindle anomalies in real-time, shops can prevent damage to the machine and avoid out of tolerance components, thereby reducing scrap and improving productivity.

Genior Modular provides an automatic real-time image of a current production process

The GEMDS system consists of an eddy current sensor, an amplifier, a connecting cable and the GEMDS monitoring module. It monitors four different sensor signals – one for displacement and three for temperature – providing real-time feedback on critical variations. It has a measuring range of 550 µm and precision down to +/- 0.2 µm.

The GEMDS can function as an intelligent stand-alone solution installed on a mounting rail in the switch cabinet. All necessary interfaces are available for easy integration into existing controls, network environments and Industry 4.0 solutions. As part of the Genior Modular product family, it can also be integrated into a Genior modular monitoring system for process monitoring purposes, making it a flexible solution that can adapt to changing needs.

The system can be managed by using eight different operating scenarios and five different static alarms for each scenario.  The display and control software run on Windows® (WIN 7/10) machine control panels or Siemens Linux systems (TCU). The software can be installed on 7 or 10” industrial PCs from Marposs or any Windows PC (WIN 7/10).

About Genior Modular

An autonomous intelligent tool and process monitoring system, Genior Modular provides an automatic real-time image of a current production process. It provides a multi-criteria monitoring strategy that automatically adapts to machining processes, meaning that the system records all relevant signals and sets the limits based on special algorithms.  During the following machining cycles, it then adjusts the automatic limits to compensate for changes in tooling and machine. The modular system design enables configuration to dedicated systems or machines as well as the ability to add capability as needed.
