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.
