The radial cutting force balance of an indexable insert drill directly affects the workpiece's depth, dimensional accuracy, and surface quality. Accurate evaluation of the radial cutting force of the indexable insert drill is necessary to guide for the improvement of the drilling performance. In this research, a new finite element simulation model of radial cutting force for indexable insert drill was proposed, and the optimal geometric parameters of the indexable insert drill were obtained based on the simulated radial cutting force balance. The accuracy of the new proposed model was verified according to the diameter deviation between the hole and the tool, showing an 80% reduction compared to the former radial cutting force model.
The radial cutting force balance of an indexable insert drill directly affects the workpiece's depth, dimensional accuracy, and surface quality. Accurate evaluation of the radial cutting force of the indexable insert drill is necessary to guide for the improvement of the drilling performance. In this research, a new finite element simulation model of radial cutting force for indexable insert drill was proposed considering the influencing regularities of cutting feed, cutting speed, and cutting width on the unit radial cutting force of the drill. The optimal geometric parameters of the indexable insert drill were obtained based on the simulated radial cutting force balance. The accuracy of the new proposed model was verified according to the diameter deviation between the hole and the tool. The difference between the hole diameter and the tool diameter was reduced by 80% for the new proposed model compared to the former radial cutting force model.
