The last decade has witnessed an explosion of interest in the cutting load analysis for multifarious tools, especially in experiments and classical 2D model. But the cutting load model for broaching tool with grooves is still not clear and functional. In this paper, a new cutting load model applied to the broaching tool, which has some grooves on the flank face of the tooth, is reported. The model takes account of the load reduction effect of grooves on the tool teeth and the load strengthening effect of the bumps on the workpiece. Then, based on the new model, the cutting load simulation analyses for 5 different types of broaching tools are presented and compared with the corresponding experimental results. The results show that cutting load can be well assessed with the proposed new model. And an interesting phenomenon is found that the grooves on the tool teeth are not the more, the better. Among the 5 different types of broaching tools researched, 4/5 type broaching tool shows the best cutting performance.
