Optical instrumentation for vibration measurement and monitoring

Monitoring of machine tool vibrations is an important aspect of precision manufacturing industry. The objective of this research is the design and experimentation of a simple and unique instrument for precise vibration measurement that can be used in industry. The instrument and the technique can also be used in a research laboratory. This paper examines the role of vibration monitoring in manufacturing systems, especially in machine tool operations and proposes a simple and reliable method using laser instrumentation. The paper outlines the design and construction of such instrument using mechatronics technology with embedded measurement. The paper also provides an analysis of the experimented data that has been collected with the new instrument. Recommendations are made for the use of this device for applications beyond machine tool vibration monitoring.
