Mesh per square inch of the drill holes, said that if 20 holes / square inch, or 20 mesh.

目数以每平方英寸的孔数表示，如20孔/平方英寸，即20目。

Simulation results of initial hole included the relationship of punch load and punch stroke, the hole profile, the distribution of stress and strain, the forming limit diagram, and the variation of the workpiece thickness. The simulation results showed good agreement with the experiments in the bore-expanding process.
