摘要

The design and manufacturing of modern cutting tools present significant challenges. To achieve efficient and high-quality machining of difficult-to-machine materials, innovative tool geometries have been developed, such as cutting tools with unequal relief angles. However, current grinding methods are inadequate for accurately processing these complex structures. Consequently, new design and grinding techniques have been introduced. In this study, the clearance is simplified into the cutting edge and the bottom curve based on key design parameters and measurement methods. Considering the contact conditions between these curves and surfaces, we propose a universal grinding method for clearance with unequal relief angles using standard grinding wheels. Numerical simulations and Vericut simulations confirm the effectiveness of the proposed design and grinding approach. Analysis of the simulation results indicates that the clearance profile is primarily influenced by the type of grinding wheel employed.
