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，研究了超声波能量对加工过程的变化的已知效果的影响。尽管该行业已经使用了超声辅助加工，但尚不清楚没有振动工具的动态运动学的超声波能量的确切效果。因此，在项目中实现了测试设置，该设置允许将加工过程与超声波场进行叠加，该过程可以以强度和频率进行调整。超声波场对加工过程的影响在工件上以表面和地下特性以及工具磨损为特征。该项目的主要挑战在于实施实验设置，而广泛的表征是劳动密集型的。因此，将在几个月内进行评估超声辅助加工的基本检查。随后在不同的超声场下进行了基于切割实验的实验设置以及基于切割实验的研究。
