摘要

在本研究中，开发了一种内置驱动超声辅助转弯系统。优化了系统的结构设计和车削参数，提高了系统的工作效率。在系统结构设计中采用有限元分析和稳健设计对系统结构进行优化。此优化的主要目的是实现系统的最佳工具提示振动位移。当系统固有频率为23.7 kHz时，计算机辅助工程模拟的最佳刀尖振动位移为4.16 μm;在输入电压为100 V时，误差为3.91µm，误差百分比为6.39%，精度很高。随后，对热处理模具钢的车削参数进行了优化研究。最佳车削力为8.658 N，车削温度为354.9℃，表面粗糙度为0.394 μm。与传统车削系统相比，UAT系统车削力降低92.32%，车削温度降低30.43%，表面粗糙度降低42.89%，刀具磨损降低95.22%。对比结果表明，该系统能显著提高模具钢热后车削效率。

Research on die steel after turning heat treatment of built-in actuation ultrasonically assisted turning system

In this research, a built-in actuated ultrasonically assisted turning (UAT) system was developed. The structure design and turning parameters of the system were optimized to improve its efficiency. Finite element analysis and robust design are used in the system structure design to optimize the system structure. The primary purpose of this optimization is to achieve the best tooltip vibration displacement of the system. When the natural frequency mode of the system is 23.7 kHz, the best-simulated tool tip vibration displacement for computer-aided engineering is 4.16 μm; at an input voltage of 100 V, it is 3.91 µm, the error percentage is 6.39%, and the accuracy is very high. Afterward, we conducted an optimization study on the turning parameters of heat-treated die steel. The best turning force is 8.658 N, the turning temperature is 354.9°C, and the surface roughness is 0.394 μm. Compared with conventional turning, our UAT system can reduce the turning force by 92.32%, the turning temperature by 30.43%, the surface roughness by 42.89%, and the tool wear by 95.22%. The comparison results show that our UAT system can significantly improve the efficiency of post-hot die steel turning.
