In manufacturing industry, nesting refers to the process of laying out cutting patterns to minimize the raw material waste. [1] Examples include manufacturing parts from flat raw material such as sheet metal, glass sheets, cloth rolls, cutting parts from steel bars, etc. Such process can also be applied to additive manufacturing, such as 3D ...
The minimum pattern count problem: to find a minimum-pattern-count solution amongst the minimum-waste solutions. This is a very hard problem, even when the waste is known. [ 10 ] [ 11 ] [ 12 ] There is a conjecture that any equality-constrained one-dimensional instance with n sizes has at least one minimum waste solution with no more than n + 1 ...
Guillotine cutting is the process of producing small rectangular items of fixed dimensions from a given large rectangular sheet, using only guillotine-cuts. A guillotine-cut (also called an edge-to-edge cut) is a straight bisecting line going from one edge of an existing rectangle to the opposite edge, similarly to a paper guillotine.
Techniques include cutting, clipping, punching, tearing, and carving of paper, as well as nalepianki in which multiple layers are glued together. Subject matter includes peacocks , roosters , and other birds; circular or star-shaped medallions ( gwiazdy ); flowers; and annual holidays such as Easter and Christmas.
A single-cut file has one set of parallel teeth while a cross-cut or double-cut file has a second set of cuts forming diamond shaped cutting surfaces. [1] In Swiss-pattern files the teeth are cut at a shallower angle, and are graded by number, with a number 1 file being coarser than a number 2, etc.
One of the main uses of choppers was to cut through the meat and skins of hunted animals to obtain food, hide, and fur. The sharpness of the tool improved the overall process. Ridges and cut marks on bones can prove their use for the task. Also, these tools were used on plants, such as digging up roots and shaving and chopping wood. [6]

A castellated beam is a beam style where an I-beam is subjected to a longitudinal cut along its web following a specific pattern. The purpose is to divide and reassemble the beam with a deeper web by taking advantage of the cutting pattern.
