In the cost of automobile stamping parts, the material cost is about more than 60%. Therefore, the economic utilization of materials is of great significance. Layout refers to the layout of parts on strip or sheet.

Unreasonable layout will cause material waste. The index to measure the economy of layout is the utilization rate of materials. It can reduce the waste area and has high material utilization rate.

Waste is divided into process waste and structural waste. Lap and surplus materials are called process wastes, which are wastes related to layout form and stamping method; Structural waste is determined by the shape characteristics of the workpiece and generally cannot be changed. Therefore, only by designing a reasonable layout scheme and reducing process waste, can we improve the utilization rate of materials.

Whether the layout is reasonable or not affects not only the economic utilization of materials, but also the quality of parts, the structure and service life of molds, the productivity of precision stamping parts and the cost of molds.

Good layout can improve material utilization, facilitate staff operation, and improve the service life of stamping dies.

Therefore, layout should follow these four principles: improve material utilization, improve operability, simplify die structure, improve service life and ensure the quality of workpiece.

The layout shall ensure the quality of precision stamping parts, and can not only consider the utilization rate of materials, regardless of the performance of stamping parts. For the blanking of bending parts, the fiber direction of sheet metal should also be considered during layout.
