一、前言众所周知,用弹簧刀进行重复切削,可获得粗糙度小的表面。弹簧刀一般用于车削、刨削或成形加工,目前尚未见到有关弹簧刀作为回转刀具使用的报道。本文就弹簧刀用于表面铣削的特性进行了研究。二、弹簧刀铣削表面的原理图1(a)为用弹簧刀铣削表面的情况。切削刃围绕主轴轴线回转,切削刃的轨迹见图1(b)所示的圆形轨迹。如果预先确定切削深度t_0(图1c),便会出现如下的切削过程: 在铣刀回转过程中,每一切削刃切削两次。当沿前半个圆周的圆弧AB(即第一次切
First, the preamble As we all know, with a knife repeater cutting, you can get a small surface roughness. Spring knives are generally used for turning, planing or forming, and no reports have been made on the use of knives as a turning tool. In this paper, the characteristics of spring cutter for surface milling have been studied. Second, spring knife surface milling principle Figure 1 (a) for the use of spring knife milling surface conditions. The cutting edge revolves around the spindle axis. The path of the cutting edge is shown in the circular path shown in Fig. 1 (b). If the depth of cut t_0 is determined in advance (Fig. 1c), the following cutting sequence occurs: During the rotation of the milling cutter, each cutting edge is cut twice. When the arc along the first half of the circle AB (ie the first cut
