Prediction of Cutting Temperature and Optimization of Process Parameters in Gear Skiving
Gear skiving has been paid more and more attention for high efficiency and wide application in gear manufacturing. In gear skiving
prediction of cutting temperature and optimization of process parameters have an important influence on increasing tool life
improving machining quality and decreasing residual stress. In this study
firstly
according to the kinematic theory of gear skiving
the entity models of the skiving tool and the workpiece are established
and then the cutting temperature nephograms on the rake face of single tooth during the cutting process are obtained based on Deform software. Secondly
aiming at the influences of the cutting velocity
feed rate and shaft angle on the maximum cutting temperature on the rake face
the prediction model of the cutting temperature under multiple parameters is established by response surface methodology. Finally
a method of process parameter optimization is proposed to maximize the machining efficiency with the constraint of cutting temperature. Combined with three groups of optimization examples
the validity of the cutting temperature prediction model is verified by comparing the error between the predicted values and simulation results under the optimized parameters. The results show that the shaft angle has the greatest effect on the cutting temperature under single parameter
the cutting velocity-shaft angle has the greatest effect on the cutting temperature under multiple parameters
and the optimized predicted values are within a reasonable error range from the simulation results. The results of this study provide methodological support for improving the machining quality and tool life in gear skiving.
