| 摘 要： | 本文提出了一种直接磨削出具有平面曲线刀刃、平面前刀面及刃带宽度等于零的模具铣刀齿槽的原理与方法.文中,首先阐述了该种铣刀的刀刃形式与齿背线的特点,然后详细研究了磨削系统应具备的砂轮相对于刀具的安装和运动形式以及运动维数,依据啮合原理和微分几何的基本知识,严格地导出了磨削系统中各运动参数之间满足的函数关系,最后设计并制造了一套专门的试验装置,它和改装后的工具磨床配套,进行磨齿加工。磨齿试验验证了本文分析的正确性。

| Abstract: | The generating principle and grinding method of the rotary burrs flutes with plane curve cutting edge.plane rake face and margin width equal to zero are proposed in this paper. The paper states the characteristics of the tool flutes,and the flutes grinding system (including motion dimensions demanded .setting parameter of grinding wheel and functions of motion parameters determined) on the basis of the conjugate theory and differential geometry. The grinding flutes experiments show that the generating principle presented in this paper is cor rect. |
