摘　　要：本文从四面刨切削原理出发,结合木工四面刨床主要结构及其运行参数,设计了四面刨切削机构的结构布局。四面刨切削的原理是一种刀刃上各点的转旋平面不平行于加工表面的周面铣削,将刨刀作用于木材工件上的力分解为水平方向的力和垂直方向的力,通过计算得出圆周上平均的切削力Fx0的经验公式,并针对刀具磨损对切削力进行修正,得出刀具磨损变钝后的单位切削力计算公式。从切屑的切削厚度出发,探讨了切削用量三要素对切削质量的影响,为四面刨切削用量的设定和调整提供参考。According to the main structure and operation parameters of the woodworkingfour-side planer,the structure layout of the planer cutting mechanism is designed according to the plane principle.The principle of plane is that the rotating plane of each point on the blade is not parallel to the surface milling of the machining surface.The force on the wood work-piece is decomposed in to a horizontal force and a vertical force.By calculating the empirical formula of the average cutting force Fxo on the circumference,and the cutting force is modified according to the tool wear,the calculating formula of the unit cutting force after the tool wear is blunt.Based on the cutting thickness of chip,the influence of three factors on cutting quality is discussed,which provides reference for the setting and adjustment of the cutting amount.
