Study on process parameter optimization of high-speed dry hobbing considering vibration characteristics
High-speed dry hobbing is an efficient and cleaner gear manufacturing technology. It is paramount to solve the serious vibration problem raised in the high-speed dry hobbing process under the high-frequent alternating cutting load
which is beneficial for improving productivity and machining accuracy.
Methods
2
To this end
an orthogonal test was performed to analyze the influence of process parameters on the hobbing vibration characteristics. Furthermore
a comprehensive indicator for evaluating the hobbing v
ibration was proposed
and the relation between this indicator and the spindle speed and the axial feed rate was developed. Based on this
a process parameter optimization model was constructed and oriented by the optimal vibration indicator and shortest cutting time.
Results
2
Compared to the original cutting conditions
the optimized cutting parameters enable the reductions of cutting time by 26% and vibration comprehensive indicator by 23%. Moreover
the dimensional accuracy of the machined gears can also be improved. The results can provide an important basis for the optimal selection of process parameters achieving the high-efficiency and high-stability high-speed dry hobbing.
