Summary

The BevelSim3D algorithm has been developed for the simulation of spiral bevel gear manufacturing. The model aims to achieve the 3D kinematic simulation of face milling and face hobbing, the generation of the undeformed solid chip geometry, and the solid tooth flank geometry. In addition, another novel calculation algorithm, called BevelForce3D, has been developed to calculate the cutting forces using the aforementioned produced undeformed chip geometries. The simulation results are validated with the geometric comparison of the simulated tooth flank geometry with the theoretical gear geometry, via the novel validation algorithm BevelCurve3D. The simulation methodology for face milling has been already described by the authors in previous work. The current study extends the functionality of the simulation model with the introduction of the face hobbing simulation and the calculation of cutting forces. Results including solid tooth flank geometry, solid chip geometry, and calculated cutting forces are presented and discussed in the paper. Investigation of the effect of crucial cutting parameters, such as generating feedrate, on the quality of the produced surface, is included in the results. Finally, the effect of three parameters, i.e., finishing stock allowance, plunge feedrate, and generating feedrate, on the undeformed chip geometry and thus the developed cutting forces, is investigated.
