According to the degree of utilization of materials, the layout of precision stamping parts can be divided into three types: waste layout, less waste layout, and no waste layout.
There are waste layout: blanking along the entire outline of the workpiece, there is process residue between the workpiece and the workpiece, between the workpiece and the strip. Because the blanking along the closed contour of the blanking member, the quality of the blanking member and the life of the die are relatively high, but the utilization of the material is low.
Less waste layout: cut or punch along the contour of the workpiece part, only between the workpiece and the workpiece, between the workpiece and the side of the strip. The blanking of this kind of arranging method is only along the contour of the part of the workpiece, which is affected by the quality and positioning of the trimming strip and the error. The quality of the cut piece is slightly poor, but the utilization rate of the material can reach 70%~90%.
No waste layout: between the blanking part and the blanking part, there is no overlap between the blanking part and the side of the strip, and the blanking part is actually obtained directly by cutting the strip, and the material utilization rate can be obtained. Up to 85%-90%. However, this method of sorting will make the quality of the cuts slightly worse.
All three methods of layout have their own advantages and disadvantages, so in the layout design of precision metal stamping parts, the advantages and disadvantages should be weighed comprehensively.
