Free-form contour packing based on material grid approximation and lowest-gravity-center methods

作者：

Highlights：

• The packing algorithm does not need to calculate NFP.

• The discretized packing points are used as a priority order.

• The packing contours are collided along four directions.

• The packing time is reduced and the material utilization rate is improved.
