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，通过刀具对加工过程的叠加振荡来降低加工功率。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，超声波在木材和木材材料中的应用对刀具参数和加工设置参数的影响尚不清楚。拟议的研究项目涉及通过诱导刀具超声波振动来提高木材和木基材料等各向异性材料的加工性能，涉及刀具寿命和加工质量。本项目的目标是开发超声辅助高性能加工实木和木材材料如中密度纤维板和刨花板的切割技术基础。根据这一目标开发的加工技术将在能源和原材料高效加工这些材料方面导致经济效率的显著提高。通过应用超声波大大降低切削力，甚至有可能使用更便宜、更少能源的机器人来代替昂贵的五轴加工中心来加工各向异性材料。

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.
