This paper reports theoretical, simulation and experimental works of rack angles effect (+15o, +5o, -5o, -15o) on cutting tool of shaping process. Three different velocities (0.2, 0.4, 0.9 m/sec) are used theoretically, assimilative and experimentally to show the effects of shear forces, shear stress and shear strain with cutting stroke. The visual Fortran program have been implemented in this study for different velocities. The auto desk inventor program is used also for different rack angles and velocities. The strain gages techniques are used to get strain readings of cutting tool during shaping process with interface equipment to translate resistance response for strain readings. There is convergence for theoretical, simulation and experimental results at positive values of rack angle and the chip moving is easily and also help to reduce the shear stress effect on cutting tool.
