Experimental Investigation of Tool Offset Variation on Cutting Tool Vibration

Ashish George J, Mr. Paramesh, Mr. Manoj, K. Lokesha


Machining has been one of the major manufacturing processes used in the industries over the years to produce high-quality products, where many parameters influence the quality of the products which include dimensional accuracy, cutting tool vibration, surface roughness, etc. In present times, advanced manufacturing industries aim at developing components by optimizing the process parameters enabling them to effectively utilise the available resources, thus saving time and cost involved. In this context, an effort has been made to investigate the significance of tool offset for turning operation of a mild steel material where experiments are performed on a lathe by varying process parameters such as spindle speed, feed rate and depth of cut. Experiments are designed using Taguchi L9 orthogonal array technique, and for every trial of experiments, cutting tool vibrations are captured with the help of tri-axial accelerometer. The influence of process parameters on vibration is analysed using analysis of variance technique which depicts that there is a significant effect of offsetting the tool on cutting tool vibration.
