Fingerprint analysis for machine tool health condition monitoring

Machine-Condition Monitoring using Vibration Analysis

Sensorless Machine Tool Condition Monitoring based on open NCs

Monitoring the state of mechanical machine tool components is of growing importance for increasing machine tool availability and reducing inspection efforts and costs. Open Numeric Controls offer a new opportunity for getting access to signals of drives as well as of the control itself and to integrate end-user’s individual applications. Because the actual drive signals contain information on t...

Condition Monitoring of CNC Machine Tool Accuracy with Renishaw Equipment

Present work deals with the accuracy of manufacturing machines and the possibility of regular diagnostic of machining centers in order to improve the quality and productivity of machining process of a CNC MCV-400 machine usingLaser calibration and Ballbar tests with the help of Renishaw equipment.The accuracy of machine tools is a critical factor that affects the quality of manufactured product...

Expert system development for vibration analysis in machine condition monitoring

Expert systems can be adapted for machine condition monitoring data interpretation due to the ability to identify systematic reasoning processes. As vibration analysis in condition monitoring is still generally performed by highly trained professionals, the use of expert systems would allow a greater analysis throughput as well as enabling technicians to perform routine analysis. The developmen...

Approximate Entropy as a diagnostic tool for machine health monitoring

This paper presents a new approach to machine health monitoring based on the Approximate Entropy (ApEn), which is a statistical measure that quantifies the regularity of a time series, such as vibration signals measured from an electrical motor or a rolling bearing. As the working condition of a machine system deteriorates due to the initiation and/or progression of structural defects, the numb...
