Investigation on the influence of cutting parameters on Machine tool Vibration & Surface finish using MEMS Accelerometer in high precision CNC milling machine

The purpose of this research is to investigate on the influences of cutting parameters on machine tool vibration & surface finish using MEMS Accelerometer in high precision CNC milling machine. The cutting parameters considered are depth of cut, feed rate and spindle speed. In this work, efforts has been made to acquire vibration data on spindle housing using MEMS Accelerometer, measure surface finish and analyse the influence of cutting parameters on machine tool vibration and surface finish using ANOVA technique and also predict the surface roughness using ANN. Here the ANOVA results for full factorial and taguchi design of experiments techniques has been compared and found that taguchi design of experiment is better and reliable to obtain optimal number of experiments. Further the cutting parameters are optimised using genetic algorithm approach, which are required to be sent to CNC machine to improve the surface roughness and control vibration.
