Aiming at the problem of severe tool wear during high speed cutting of super-strength steel,high speed cutting experiments on super-strength steel were carried out using cermet tools to establish a prediction model of tool wear rate.Taking cutting speed,feed and axial cutting depth as design variables,and minimum tool wear rate and maximum cutting efficiency as optimization objectives,the optimal combination of cutting process parameters was obtained by optimizing the cutting process parameters based on genetic algorithm.

Key words: super-strength steel, cermet tool, high speed cutting, cutting process, parameter optimization
