Tools used in cutting processes with multi-flank chip formation like gear hobbing or bevel gear cutting, often reach their tool life due to excessive wear at the tool corner radius. Tool wear depends on the strength of the cutting edge and on the thermal and mechanical load. The objective of this work is to analyze the thermal and mechanical tool load during multi-flank chip formation. As the tool load cannot be measured in the necessary high local resolution, a finite element based machining simulation is used to model the process of chip formation. The simulation is able to calculate the temperature and stress distribution along the cutting edge. For the examinations presented in this report the bevel gear cutting process for ring gears is simulated. The simulation results show a significant thermal and mechanical load maximum at the tool corner, where the maximal wear occurs in cutting.

Based on spiral bevel gear NC manufacture principle and generating motion of the generating gear and the work gear, the NC generation of spiral bevel gear cutting is realized by means of the vector transformation. As sophisticated calculation of the transformation is hard to implement in each interpolation cycle of NC machining, the coordinated motion of NC coordinate axes is expressed as quintic parametric spline functions, which use the rotation angle of the work gear as the parameter. The constrained optimization method of three design variables is established to obtain contacting points of gear tooth surfaces, which are acquired by solving nonlinear equations sets traditionally. The condition of normal coincidence is simplified and the object function of the equal position vectors of mating gears is established. The contacting points of gear tooth surfaces can be used for tooth contact analysis. The parametric curve interpolator is combined with spiral bevel gear NC machining, and is applied to the self-developed spiral bevel gear NC milling machine to control the gear cutting. Experimental results show that the proposed method is feasible and effective in the control of NC machining for the spiral bevel gear.

The tooth geometry and cutting machine mechanisms of spiral bevel gears are investigated. Based on the kinematics of titled head cutter, machine cradle, sliding base and work head, the matrix presentation of spiral bevel gear’s tooth geometry are developed. The relations between the parameters of the proposed mathematical model and the machine settings of existing spiral bevel gear cutting machines are also investigated. The tilt of head cutter axis, motion of generation, helical motion of sliding base, and nongenerating cutting of spiral bevel gears are taken into consideration. An example is given to illustrate the application of the proposed mathematical model.
