Simulation Analysis of Cutting Resistance for Cutting Tools with Different Rakes in the Strike Working Condition

Abstract:

Brush-cutter would always bring cutting shock in its cutting process, and its not easy to estimate the cutting resistance by usual cutting theory and methods. The present paper emulates real cutting process by using ANSYS/LS-DYNA, and orthogonal anisotropy model was used to symbolize the wood material. The result shows that the cutting tool with a 40 degrees rake is more competent than the ones with 30 degrees and 50 degrees. This result fits common cutting theories, thus the rationality of this research is proved, and a cutting resistance curve is obtained.
