In the cost of stamping parts, material cost accounts for more than 60%, so the economic utilization of materials is an important issue. The standard to measure the layout economy is the utilization rate of materials, that is, the ratio of the actual surface area of the workpiece to the area of the sheet metal.<br>Actual area of workpiece: =13586<br>Utilization rate of materials: = × 100%<br>Area of material used: = 20880<br>So the utilization rate of materials is: = × 100% = × 100% = 65.07%<br>At present, using computer layout can determine the optimal plan accurately and quickly. The main application software is AutoLayout, which is widely used. The application of automatic layout will greatly reduce the cost of materials, shorten the production cycle and improve the process efficiency of personnel<br>
