Fundamental investigation on oscillation-superimposed machining of wood and wood-based materials

在以前的金属深孔钻削研究中，加工功率的降低是通过切削刀具对加工过程的叠加振荡来实现的。这种加工力和扭矩的减少导致了刀具寿命的延长和工件质量的提高。与金属加工相比，木材和木材材料中应用超声波的工具参数和加工设置参数的影响仍然是广泛未知的。拟议的研究项目涉及通过诱导工具超声波振动有关的工具寿命和加工质量的各向异性材料，如木材和木基材料的加工性能的提高。本项目的目标是开发超声波辅助高性能加工实木和木质材料（如中密度纤维板和刨花板）的切割技术基础。基于这一目标，开发的加工技术将大大提高能源和原材料方面的经济效率，有效地加工这些材料。通过应用超声波的帮助，大大降低了切削力，甚至可以使用更便宜和更少的能量需要机器人，而不是昂贵的5轴加工中心加工各向异性材料。

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.
