Difficulties in the design of curb stone molds
May 13, 2023| 1. Rational use of materials
Material utilization rate: the percentage of the actual area of blanking parts and the sheet area used, which is an economic indicator to measure the rational use of materials.
Material utilization within 1 step
The total material utilization rate on 1 sheet (or strip or strip).
Cutting essentials of sheet metal
2. The essentials of improving the utilization rate of materials
Waste generated by blanking: Type 1 is layout waste; The other category is process waste.
Process scrap vs. layout scrap
The layout scrap is determined by the shape of the part itself, 1 is usually firm and stable; The process waste depends on the size of the lap edge and allowance, as well as the nesting and stamping requirements. Therefore, in order to improve the utilization rate of materials, it is necessary to arrange samples reasonably and eliminate process waste.
