Nonorthogonal Two-Dimensional Cutting Patterns
研究从卷材上切割多个零件的最优方式，允许零件倾斜放置，推导了非正交切割模式的性质，可在计算量小幅增加下实现显著节省。
The optimal way to cut a number of pieces from a reel is usually studied under the assumption that each piece has one of its sides parallel to the reel edge. If the material to be cut is homogeneous, it may be attractive to consider patterns in which certain pieces appear in an intermediate, tilted position. Certain properties of a class of such nonorthogonal cutting patterns axe derived that make it possible to allow for tilting in a simple manner. Substantial savings may thus be realised at the expense of a modest increase in computational effort.
