Abstract
Machine tool has been used for manufacturing of various precise and adverse components which have wide engineering applications throughout the world. The use of a machine tool as a manufacturing tool is inevitable. The problem that has been faced with the machine tool is the effect of vibration which results in loss of accuracy and stability of the process. This paper aims at reducing the vibration values of lathe tool post by incorporating a control system in the form of Shape Memory Alloy-Dynamic Vibration Absorber (SMA-DVA). The LabVIEW software is used to record the acceleration, frequency and displacement plots before and after installation of DVA. The DAQ (Data AcQuisition) card serves as an interface between the LabVIEW software and Accelerometer in recording the readings and plots. The turning operation is performed in lathe without installation of DVA and is performed again after installation of DVA. The RMS value of acceleration is taken for comparison and the percentage reduction of RMS value is calculated. From the percentage reduction values, the effectiveness of the installed DVA is found out.
