摘要
根据实体截面轮廓的特点，首先对实体截面轮廓内外边界的自动识别方法作了研究，并根据其边界的内外性、走向和各轮廓顶点的凹凸性提出了确定加工轨迹的线宽自动补偿矢量的计算方法，从而为快速原型制造技术中的线宽自动补偿创造了条件。
The problem of automatic compensation for the line-width in rapid prototyping &. manufacturing technology is discussed in this paper in detail. Firstly, a method of automatic recognition of the inside and outside boundaries among the solid cross-section contours is studied. Then, starting with the feature of the solid cross-section contours an automatic vector of the line-width can be quickly determined in accordance with the direction of a boundary and its inside and outside feature, the concave and convex of the vertex in the contours. The research results will offer the condition of the automatic compensation for the line-width in the rapid prototyping & manufacturing technology.
