铣削的铣刀扰动力确定和均布作业条件

Determination of Disturbing Force for Milling Cutter in the Course of Decorticating and Conditions of Evenly Distributing Working

铣削剥皮是原木剥皮机床的一种作业方式。在铣削过程中铣刀承受周期性负荷变化 ,作业很不平稳 ,产生振动的扰动力。通过计算平均切削力、实际切削力和最大切削力 ,确定了扰动力和切削功率 ,找出了铣削剥皮时铣刀保持平稳工作状态的参数关系。

Milling decortication is a kind of job method for log disbarking machine. In the course of decorticating, disturbing force of vibration will come into being due to the unstable job resulted in cyclic loading variation supported by milling cutter. Cutting power of disturbing force can be determined by calculating average, actual and maximum cutting force, and parameters which are related to stable condition of milling cutter were also figured out during decorticating.
