一、前言成形铣刀为专用刀具,由于它加工生产率较高以及对工件的廓形精度较易保证.所以,在成批和大量生产时应用较为广泛. 成形铣刀有铲齿和尖齿两种类型,由于铲齿成形铣刀用钝后重磨前刀面比较方便,所以生产上常用之。铲齿成形铣刀的几何参数和结构参数,在刀具教科书和有关资料中都有介绍。设计时,当加工对象和技术要求明确后,一般是通过“合理选取”来确定这些参数的。很显然,这种合理选取大多是凭经验进行的,所以其合理性是值得推敲的。为此,本文介绍优化方法,在保证工件精度的前提下,寻求铲齿成形铣刀的最佳几何参数和最佳结构
First, the foreword Forming cutter for special tools, due to its high processing productivity and the workpiece contour accuracy easier to ensure.So, in the mass and mass production is more widely used.Shaped cutter with two teeth and tines two Type, due to the use of blunt-tipped cutter after blunt resurfacing rake more convenient, so commonly used in production. The geometry and structural parameters of the spatula forming cutter are described in the tool textbook and the related information. Design, when the processing of objects and technical requirements are clear, the general is through the “reasonable selection” to determine these parameters. Obviously, most of this reasonable selection is based on experience, so its rationality is worth considering. To this end, this article describes the optimization method, to ensure the accuracy of the workpiece under the premise of seeking the best profile cutter geometry and the best geometry
