刀具的切屑控制主要采用两种方式,一种是断屑槽,另一种是更新式的成屑槽,从原理上看,断屑槽的作用是将已形成的切屑折断,而成屑槽的主要作用则是在切削中使切屑“成形”,使其折断。两者比较,成屑槽的性能更为先进。以下介绍几种用于切断刀的成屑槽结构型式,供刀具设计时参考。一、直角槽型成屑槽(图1) 这种成屑槽产生的切槽比槽窄,因成屑槽的中部是一U型截面,切屑由此U形面产生。这种成屑槽贯穿在切削刃宽度上的两个截然不同的区域。从理论上讲,在整个刀具宽度上,
Chip control of the tool is mainly used in two ways, one is chipbreaker, the other is a newer type of chipbreaker, in principle, the role of chipbreaker has been formed chip breakage, and into the chip flute The main role is to make chips in the cutting “forming” to break it. Comparing the two, the performance of the chip flute is more advanced. The following describes several types of chip flutes used to cut the knife structure for tool design reference. First, the right-angle groove into the chip trough (Figure 1) This into the chip trough groove than the narrow slot, because the middle of the chip trough is a U-shaped cross-section, the chip generated U-shaped surface. This chip flute runs through two distinct areas in the width of the cutting edge. In theory, across the entire tool width,
