虽然出现了各种结构的精铣端铣刀,但还没有一种得到了生产上的广泛采用。据我们所知,迄今很少有人从理论上对精铣端铣刀进行分析比较,而作理论上的研究以探讨新型精铣端铣刀结构又是十分重要的。因此,本文试图在这方面做一些工作。文中首先从理论上研究现有端铣刀精铣铣削方式,典型精铣刀结构及其在各种进给量下的加工表面波度H_o。在对各种典型的圆弧刀刃精铣端铣刀进行分析比较之后,指出圆弧刀刃投影在切削基面上的曲率半径R的大小对H_o和许用进给量的大小有着重大的影响。现有的圆弧刀刃刀片的精铣端铣刀,
Despite the emergence of a variety of structures, fine milling end mills, but no one has been widely used in production. To the best of our knowledge, so far few people have theoretically analyzed and compared the fine milling end mills, and it is very important to do theoretical research to explore the structure of the new fine milling end mills. Therefore, this article attempts to do some work in this area. In this paper, firstly, the paper studies the finishing milling method of the existing end mills theoretically, the structure of the typical milling cutter and its processing surface wave H_o under various feed rates. After analyzing and comparing various typical arc edge finishing milling end mills, it is pointed out that the radius of curvature R of arc edge projection on the cutting base surface has a great influence on the size of H_o and allowable feed. The existing arc blade edge milling cutter end mill,
