Topology Optimization of Single Point Cutting Tool with Hypermesh Optistruct

In this paper single point cutting tool is modeled using PTC parametric Creo 3.0 and exported to HyperMesh software (OptiStruct) for the analysis of deflection and stress for different tool angles at constant loading and best tool angles are identified from the analysis. Afterwards a model of single point cutting tool is developed for best angles. For verification of results, physical models of initial geometry and final geometry are prepared by grinding angles on HSS tool bits and several cutting experiments are performed at different cutting conditions. Results show that the final geometry has shown less deflection than initial geometry. Hence, it is considered as optimal geometry. This geometry is further modelled and its volume is minimized within the allowable deflection limit using topology optimization method in HyperMesh OptiStruct software.
