Abstract: In this paper, through analysis, decision variables and constraints are determined, and the optimal layout model, rectangular layout model and integer programming model are established, and the optimal cutting scheme of parts is analyzed and studied. Combined with the current research, referring to the tight structure of a circle and the transformation in the affine coordinate system, the tight structure of the ellipse is put forward, and the optimal cutting scheme of the elliptical industrial parts is designed.

Keywords: ellipse layout; integer programming; layout optimization; two-dimensional cutting scheme

在大型工业产品中,如机床、轮船及飞机常常需要很多的小零件,如螺钉、螺帽、螺栓和活塞等。(剩余2600字)
