| 中文摘要 | 本文提出球型端銑刀的銑削力學預測模式之發展與驗證。此力學模式主要是由金 屬切削理論與球型端銑刀的銑削幾何關係所推導。本文提出一個簡潔的方法來描述球型端銑 刀的複雜幾何。此方法是利用一球面和一歪面的相交曲線來描述球型端銑刀球部上的切刃幾 何。此種產生的方法,不僅簡化了對切刃幾何的描述,而且它還提供了球型端銑刀與單點刀 具之全部所需的相關幾何參數的發展基礎。此發展的力學模式能夠處理各種程序變數,其中 包含軸向、徑向切削深度和進給之變化。此切削力學模式由實驗驗證顯示,結果相當一致。 |
| 英文摘要 | This paper presents the development and verification of a predictive model for the force system in ball-end milling. The force model is essentially derived from the metal cutting theory and for the geometric relations of the ball-end miling process. A concise method for characterizing the complex geometry of a ball-end mill is first determined. This method of generation not only simplifes the description of the geometry of the cutting edge, but it provides the basis for the determination of all geometric parameters to an accuracy commensurate with that needed for oblique cutting process. The force model developed is able to deal with many of the process variables, including changes in the axial and radial depths of cut and in the feedrate. As a result, the predicted cutting forces show a fairly good agreement with the values from the verification experiments. |
