1. Frame problem refers to a known figure or structure, and a larger structure or figure can be constructed by adding different components. This is a way to solve mathematical problems. In the frame problem, some already built graphs or structures are usually given, and then a new graph or structure is needed, which requires a basic graph and some additional elements to complete.
2. Forging is a method to change the shape and properties of iron, copper, steel and other substances by physical means, so as to make them into required workpieces or products. This is a technical problem involving materials science, engineering and other fields. In forging, it is necessary to physically deform the material, the main purpose of which is to obtain the required shape and physical properties. Usually, heating, cooling and other processes are needed to get the required shape.
To sum up, frame problem and forging problem are both methods to solve problems in specific fields, but their purposes, contents and methods are quite different.
