(1) A 2438mm ×496mm plate can be cut into 770mm × 109mm plate 12 and 2000mm×46mm plate 1 block; Four 770mm × 109mm plates can be cut with another 2438mm ×496mm plate;

② A 3048mm ×396mm plate can cut 9 770mm × 109mm plates and 1 2000mm×46mm plates;

In a word, four pieces with different specifications, two pieces for each piece, can be used to process the required small plates with two specifications and quantities, but from the point of view of easy utilization of the remaining materials, it is better to use 2438mm ×496mm plates for blanking.
