1、引言在所有的切削工序中,切断仍然是一个最成问题的工序,专为切断工序而发展的各系统,起初用高速钢加工,后用钎焊硬质合金的刀具,继而用可转位硬质合金刀片的刀具,但都只是部分地解决切断所碰到的问题。考虑切断时出现的现象,为一新型切断系统所选择的许多必要条件都以可转位硬质合金刀片的自夹作用为基础。该新系统由硬质合金
1. INTRODUCTION In all cutting operations, cutting is still one of the most problematic processes. The systems developed specifically for the cutting process are initially machined with high-speed steel and later brazed with cemented carbide cutting tools, which in turn are transferable Bit carbide cutting tool, but only partially solve the problems encountered by cutting. Considering the phenomena that occur at the time of cutting, many of the necessary conditions selected for a new cutting system are based on the self-clamping action of indexable cemented carbide inserts. The new system consists of cemented carbide
