Marposs Corp.’s (Auburn Hills, MI) Artis GEMVM system monitors vibration, gravity, and temperature values to detect machining anomalies, such as damage to spindle bearings or drive-axle wear. The system initiates an alarm in less than 1 millisecond of a change, a super-fast response time that makes it a highly effective solution for predictive maintenance as well as simple process monitoring and collision detection.
Depending on sensor type, the system measures acceleration in up to 3 axes with a measuring frequency of up to 5.6kHz and a sampling rate of 25kHz. It has eight definable and selectable operating modes with five freely activatable static alarms. Any events that violate the predefined hard-stop limits are logged in the event memory with relevant information for later analysis.
The system comes with Artis VisuScope diagnostic tool to ensure the quality of new machines and those in operation. Process analyses based on determined data enable historical comparison of machine states, evaluation of damages, and the control after repairs.
The GEMVM can function in stand-alone mode, running on Windows (WIN 7/10) machine control panels or Siemens Linux systems (TCU). Or, the software can be installed on 7- or 10-inch industrial PCs from Marposs or any Windows PC (WIN 7/10). Or it can be integrated into a Genior Modular monitoring system for process monitoring, delivering vibration velocity and acceleration to a processing unit for further evaluation.
Genior Modular provides a multicriteria monitoring strategy that automatically adapts to machining processes, meaning it records all relevant signals and sets limits based on special algorithms. During subsequent 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.
