This paper compares UEVC (ultrasonic-elliptical-vibration-cutting) and a CC (conventional-cutting) process for micro-grooving in AISI 1045 via FEA (finite-element-analysis) in 2D orthogonal technique. The stress, cutting force, temperature, and residual stress have been examined. Average cutting forces in UEVC can be decreased when the velocity ratio is reduced. The average cutting forces in UEVC are declined as the vibration magnitude increases and inclined as the feed velocities and DOC increases. The stress concentration and peak cutting tool temperature in UEVC are higher than those in the CC technique because of the higher relative cutting velocity. Additionally, the peak thrust force in UEVC is larger than that in the CC technique. The main simulated residual stresses for both processes are tensile stresses, which decrease rapidly in UEVC. The compressive stress in UEVC can be more negative than that in the CC technique owing to the compression effect of the vibrated cutting tool.

在 AISI 1045 中进行微开槽期间的超声波椭圆振动切削 (UEVC) 中的有限元分析

本文通过二维正交技术中的 FEA(有限元分析)比较了 UEVC(超声波椭圆振动切割)和 CC(常规切割)工艺在 AISI 1045 中的微槽加工。已经检查了应力、切削力、温度和残余应力。当速度比降低时,UEVC 中的平均切削力可以降低。UEVC 中的平均切削力随着振动幅度的增加而下降,并且随着进给速度和 DOC 的增加而倾斜。UEVC 的应力集中和刀具峰值温度高于 CC 技术,因为相对切削速度更高。此外,UEVC 中的峰值推力大于 CC 技术中的峰值推力。这两个过程的主要模拟残余应力是拉伸应力,在 UEVC 中迅速降低。
