Analysis of stress behavior of drill tool by using ANSYS-2020 R2

Twist drill is a very prominent tool, used in drilling operations. But although, its geometry is complex and high stress concentration develops near the cutting edges, which causes tool failure. In this paper, it was aimed to analysis the stress and deformation parameters of drill tool used in traditional machining process, which is of a great importance in the manufacturing industry. In this analysis, twist drill is being designed on Solid works platform and stress is calculated by implementing cutting parameters (such as 5155 N-mm torque and cutting force, 1390 RPM spindle speed etc.) on ANSYS-2020 design software. Finally, the results of the analyses reveal stress distribution and deformation value on the twist drill based on the normalized distance of all points with reference to the axis of rotation of the tool. Our main spotlight will be on deformation and stress analysis using conventional drill bit. The significance of this analysis becomes more important as it reduces various expenses and labor effort. This stress analysis approach can also be implemented to the other metal removal tool, which is being used in turning and milling operations and evaluation can be made regarding the design of multi point cutting tool.
