數值控制工具機切削之二維空間數學模型

Abstract

一般而言，數值控制工具機切削路徑之決定，頗為複雜，人工設計費時，宜改採用計算機輔助設計；本文提供一種簡潔設計方法，首先將二維空間的物面結構分為五種，經由此五種物面的組合可得任何一種較複雜之物面。文中提供計算機輔助設計之技巧，以達成物面切削之全面自動化設計，而縮短設計時間。其所需之記憶空間不必很大。

Generally speaking, the determination of a cutting path for an NC machine tool is relatively complicated.The manual design of such a path is time-consuming.It is better to implement a computer-aided design system. The paper presents a consise method for this task. Firstly, the two-dimensional surfaces are categorized into five types of basic surfaces.Any complex surface can be represented by a combination of these five basic surfaces. A computer-aided design procedure is proposed to achieve automatic determination of a cutting path. The design time is thus cut down. And the memory space required is manageable.
