数控机床铣螺纹用盘形铣刀的近似造型及误差计算

Mould-Making and the Calculate of Tolerance for the Dish-Mill Tool in the Numerical-Control Machine Thread is Made

在数控铣床上加工螺纹，需要设计盘形铣刀。本文求导了铣刀宽度计算公式，分析了产生误差的原因，并提出了改进措施。

Tread is machined using numerical - control machine. Mill tool is designed. The calculated formula of the mill tool width is inferred,and the reason of tolerance is analyzed, and the improved measure is put.
