Abstract: The purpose of this study was to determine the Single point cutting tool deflection due to cutting forces which were developed because of different parameters like feed, depth of cut, cutting speed and also because of geometrical parameters of cutting tool like side cutting edge angle and side rake angle and further comparing between side rake angle and side cutting edge angle. Firstly the cutting forces were measured using dynamometer which is taken from reference, then finite element method (FEM) was used to obtain the cutting tool deflection which is finite element analysis (FEA). The FEA results were then validated using cantilever beam model results. The predicted results from FEA were very close to the theoretical study. Though the prediction from FEA and the theoretical results are reasonably accurate.
