The performance of the cutting tool subjected to vibration depends upon the operational parameters of the systems. The experimentation is the most reliable means of investigating the vibrational behaviour of the cutting tool during the turning operation on work-piece. However, the empirical expressions developed based on the well-designed experimental observations give much reliable predictions. Hence, the core objective of the present study is to apply design of experiment (DOE) approach on the vibration study of cutting tool considering the four key variables: rotational speed (N) of the spindle i.e. work-piece, feed rate (f), depth of cut (DOC) (dc) and the work-piece diameter (D). Based on the observations, the optimum parameter values identified are: N = 350 RPM, f = 0.15mm/rev, dc = 0.3 mm and D = 40 mm. Moreover, the second order polynomial equation with cross-terms has been identified as the more suitable regression expression than the second and third order polynomial.
