Trial and error experiments are the dominant approaches to select machining settings and also cutting system design in face-hobbing of bevel gears. These time-consuming experimental tests impose undesired costs to industries. In the present paper, an integrated method is proposed to find optimum machining settings in face-hobbing based on minimum machining time and allowable cutting force and tool wear. Cutting blades in face-hobbing are converted to many infinitesimal oblique elements along the cutting edge, and the cutting forces and the tool wear are predicted on all these small elements. The constructed optimization problem seeks a face-hobbing scenario with minimum plunge time which meets the cutting force or crater wear depth constraints. The proposed method is applied in two case studies successfully to show the capability of the approach.
