In this project, the impact of the known effect of material softening under the action of ultrasonic energy on a machining process is investigated. Although ultrasound-assisted machining is already used in the industry, the precise effects of ultrasonic energy without the dynamic kinematics of a vibrating tool are not yet known. Therefore, a test setup is implemented within the project that allows a superimposition of a machining process with an ultrasonic field that can be adjusted in intensity and frequency. The effects of ultrasonic field on the machining process are characterized on the workpiece in terms of surface and subsurface properties, as well as tool wear. The main challenge of this project lies in the implementation of the experimental setup, while the extensive characterization is labor-intensive. Therefore, within the few months, basic examinations to evaluate ultrasound-assisted machining will be carried out. The implementation of the experimental set-up as well as the investigations based on cutting experiments under a varied ultrasonic field follow.

在该项目中，研究了超声波能量作用下已知的材料软化效应对加工过程的影响。尽管超声波辅助加工已在行业中使用，但在没有振动工具动态运动学的情况下超声波能量的精确效果尚不清楚。因此，在项目中实施了一个测试设置，允许将加工过程与可调整强度和频率的超声波场叠加。超声波场对加工过程的影响通过工件的表面和次表面特性以及刀具磨损来表征。该项目的主要挑战在于实验装置的实施，而广泛的表征是劳动密集型的。因此，在几个月内，将进行评估超声辅助加工的基本检查。接下来是实验装置的实施以及基于不同超声波场下的切割实验的研究。
