The correlation of vibration signal features in grinding of advanced ceramics
(2016-09-01)
Monitoring the grinding of ceramics using the vibration signal has been presented as an alternative for the diagnosis of the workpiece surface. This paper has the objective of studying the vibration signal through spectral ...
Digital signal processing for self-vibration monitoring in grinding: A new approach based on the time-frequency analysis of vibration signals
(2019-10-01)
The occurrence of chatter can generate parts outside the dimensional and geometric tolerances or even cause irreversible damage, such as changes to the hardness and surface roughness of the ground part. The objective of ...

Feature extraction using frequency spectrum and time domain analysis of vibration signals to monitoring advanced ceramic in grinding process
(Inst Engineering Technology-iet, 2019-01-01)
New alternatives for monitoring the ceramic grinding process have been studied. Monitoring vibration signals is one of the most successful methods because some characteristics that describe the behaviour and influence of ...
Monitoring of Self-Excited Vibration in Grinding Process Using Time-Frequency Analysis of Acceleration Signals
(Ieee, 2018-01-01)
Grinding is a finish manufacturing process for high precision parts. As the part has high value added at this stage, anomalies and defects are unacceptable. Self-excited vibration or just chatter is an undesirable and ...

Some diverse examples of exploiting the beneficial effects of geometric stiffness nonlinearity
(2019-06-15)
The effects of nonlinearity, particularly stiffness nonlinearity, has been of concern to structural engineers for many years. The main reason for this is because this type of nonlinearity can cause unpredictable dynamics, ...
Mate searching in Ennya maculicornis (Membracidae: Polyglyptini) initiated by females: behavioural and acoustic descriptions
(Blackwell Publishing Ltd, 2019)
1. In treehoppers in which courtship has been studied, males initiate the search for females by periodically emitting a vibrational signal. The responses by the female are used by males as a beacon and give rise to a duet. ...
Narrowband feedback for narrowband control of resonant and non-resonant vibration
(2016-08-01)
This paper presents a simple feedback methodology that uses second order filters to control narrowband resonant and non-resonant vibration of a structural system. In particular, a single degree-of-freedom system is studied ...
Tool condition monitoring of single-point dressing operation by digital signal processing of AE and AI
(Elsevier B.V., 2018-01-01)
This work aims at determining the right moment to stop single-point dressing the grinding wheel in order to optimize the grinding process as a whole. Acoustic emission signals and signal processing tools are used as primary ...
