In previous studies for deep-hole drilling of metals a reduction of the processing power has been achieved through superimposed oscillations of the cutting tool to the machining process. This reduction of machining forces and torques led to increased tool life and better quality of the workpiece. In contrast to metal-working the effect of tool parameters and machining setting parameters of the applied ultrasound in wood and wood materials is still widely unknown. The proposed research project concerns the increased performance of the processing of anisotropic materials such as wood and wood-based materials through induced tool ultrasonic vibrations regarding the tool life and the processing quality. The goal of this project is developing the basics of cutting technology of ultrasound- assisted high-performance machining of solid wood and wood materials such as medium density fiber board and particle board. Based on that goal to be developed processing technologies will lead to a significant improvement of the economic efficiency in terms of energy- and raw materials efficient machining of these materials. Through with the help of applied ultrasound greatly reduced cutting forces, it could be even possible to use cheaper and less energy requiring robots instead of expensive 5-axis machining centers in machining of anisotropic materials.

在以前的对金属进行深孔钻孔的研究中，通过将切割工具的振荡降低到加工过程中，可以降低加工能力。加工力量和扭矩的减少导致工具寿命的提高和工件的提高质量。与金属加工工具参数的效果以及木材和木材材料中应用超声的加工设置参数的效果仍然是未知的。拟议的研究项目涉及通过诱导的有关工具寿命和加工质量的工具超声振动的各向异性材料（例如木材和木材基材料）的加工性能提高。该项目的目的是开发切割技术和木材材料（例如中密度纤维板和颗粒板）的超声辅助高性能加工技术的基础知识。基于这一目标，要开发的加工技术将在能源和原材料有效加工这些材料方面的经济效率显着提高。通过施加的超声波大大降低了切割力，甚至有可能使用更便宜，更少的能量来进行机器人，而不是昂贵的5轴加工中心，以加工各向异性材料。
