摘　　要：随着数控技术的快速发展,铣刀在机械制造业中的应用越发广泛,但因铣刀结构复杂,部分高职生对铣刀的认知不是很清晰。本文坚持化繁为简的思路,即将复杂问题简单化、直观化,将铣削概念用实例来讲解以加深学生的理解,吸引学生积极主动思考,准确把握铣刀的相关技术要素。本文将从铣削平面用铣刀的几何参数、铣削用量、铣削层参数、铣削力的分解、铣削方式、铣刀几何参数的选择等方面逐一进行难点分解。With the rapid development of numerical control technology,milling cutters are widely used in ma‐chinery manufacturing industry,but because of the complex structure of milling cutters,part of the higher voca‐tional students'cognition of milling cutters is not very clear.This paper adheres to the idea of simplifying complex problems,that is,simplifying and visualizing complex problems,and explaining the milling concept with examples to deepen students'understanding,attract students to actively think,and accurately grasp the relevant technical ele‐ments of milling cutters.This paper will decompose the difficulties one by one from the geometric parameters of milling cutter for milling plane,milling amount,milling layer parameters,decomposition of milling force,milling mode,selection of geometric parameters of milling cutter,etc.

关 键 词：铣刀几何参数 铣削用量 铣削方式 铣削力的分解 背前角 侧前角
