Numerical Investigation of the Derivative Cutting Effect of Micro-Textured Tools in Dry Cutting of Ti6Al4V

Abstract:

In this study, FEM simulation of titanium alloy machining with micro-textured tool using Thirdwave AdvantEdge. Micro-scale textures on the rake face of the cutting tool is a single linear groove parallel to the cutting edge. Viewing simulation results ,derivative cutting did occur under the cutting parameters in this study. The tool-chip contact length decreases due to the existence of the micro-textures. Shear angle increases which indicates smaller deformation of the cutting layer and thus smaller cutting forces and cutting temperature. However, the derivative cutting effect increases the variations of the cutting forces. Therefore, strength of the cutting tool must be taken into consideration during the designation of the micro-textured cutting tool.
