The prediction of vibration between the tool and work piece is important as guideline to the machine tools user for an optimal selection of depth of cut and rotation of spindle to minimize the vibration.Machining is a complex process in which different parameters can deleterious the desired result. Among them, cutting tool vibration is an important which influences dimensional precision of components machined, life of the cutting tool is very important. Cutting tool vibration are mainly produced cutting parameters like cutting speed, depth of cut and tool feed rate. In this work, the cutting tool vibrations are controlled in lathe machine where the tool holder is supported with and without damping pad. The cutting tool vibration signals were controlled through FFT analyzer. To predict and validate result by using Taguchi method, Experimental studies and data analysis have been performed to validate the proposed damping system. By using regression analysis best suitable equation is developed to predict the probable value response for given predictor value.

Introduction Metal cutting or simply machining, is one of the oldest processes for shaping components in the manufacturing industry. To remain in business, manufacturing companies have to machine the components at required quality with minimum possible cost and hence the tool life becomes a most important aspect for manufacturing engineers and researcher. The challenge of modern machining industries is focused mainly on the achievement of high quality, in terms of work piece dimensional accuracy, surface finish, high production rate, less wear on the cutting tools, economy of machining in terms of cost saving and increase the performance of the product with reduced environmental impact. Tool wear weakens the cutting tool, increases the forces used in cutting and causes a lack of consistency in material removal. Machine and machine tool are always subjected to vibration. These vibrations are mainly causes due to In-homogeneity’s in the work piece material Variation of chip cross section Disturbances in the work piece or tool drives Dynamic loads generated by acceleration/deceleration of massive moving components Vibration transmitted from the environment Self-excited vibration generated by the cutting process or by friction (machine- tool chatter). The tolerable level of relative vibration between tool and work piece, is determined by the required surface finish and machining accuracy as well as by detrimental effects of the vibration on tool life. 1.1 Vibration Due to in homogeneities in the Work piece Hard spots or a crust in the material being machined impart small shocks to the tool and work piece, as a result of which free vibrations are set up. When machining is done under conditions resulting in discontinuous chip removals, the segmentation of chip elements results in a fluctuation of the cutting thrust. If the frequency of these fluctuations coincides with one of the natural frequencies of the structure, forced vibration of appreciable amplitude may be excited. However, in single edge cutting operations, it is not clear whether the segmentation of the chip is a primary effect or whether it is produced by other vibration, without which continuous chip flow would be encountered. The breaking away of a built-up edge from the tool face also imparts impulses to the cutting tool which result in vibration. However, marks left by the built-up edge
