Methods, apparatus, and systems for cutting material used in fused deposition modeling systems are provided, which comprise a ribbon including one or more perforations. Material is passed through at least one perforation and movement of the ribbon cuts the material. A further embodiment comprises a disk including one or more blade structures, each forming at least one cavity. Material is passed through at least one cavity and a rotational movement of the disk cuts the material. A further embodiment comprises a slider-crank mechanism including a slider coupled to a set of parallel rails of a guide shaft. The slider moves along a length of the rails to cut the material. Yet another embodiment comprises one or more rotatable blade structures coupled to at least one rod. The rotation of the blade structures causes the blade structures to intersect and cut extruded material during each rotation.

A knife holder has a base and a knife support portion extending from the base. The knife support portion includes a distal edge and a knife support surface for supporting a knife. The knife support surface includes a shaped portion and a relieved surface. The shaped portion has a wavy shape and is located adjacent the distal edge. The relieved surface does not have a wavy shape and is located on the knife support surface so that at least part of the shaped portion is between the relieved surface and the distal edge. An abutment surface is between the base and the relieved surface and is defined by the relieved surface.

An automated pizza cutter with a blade and a pizza resting on a working surface. Horizontal, vertical and/or rotational relative movement between the blade and the pizza is effected by different embodiments. The working surface can be moved rotationally relative to the blade, and the blade may be moved horizontally and/or vertically relative to the working surface. In one embodiment, a rotatably driven table supports a pizza while a blade disposed above the table is configured to move vertically and horizontally. A programmable user interface allows operation of the cutter. After the cutting process is completed, a blade cleaner wipes the blade of debris, which eliminates cross contamination between different types of pizzas.

A circle cutting system with a blade coupled to a body that rotates and is pressed into sheet material for the separation of circular portions from a larger sheet of the material, such as roofing material.

Some examples of a cable cutting system include a first cutting apparatus that includes a recess to receive a cable. The system includes a second cutting apparatus separate from and attached to the first cutting apparatus. The second cutting apparatus includes multiple cutting surfaces arranged to cut the cable received at the recess.

In order to avoid underweight of slices when slicing a loaf into slices, thickness adjustments specified for slicing are adjusted depending on different pre-known parameters, from loaf to loaf and/or from slice to slice within one and the same loaf, preferably also across the boundary between two loaves optimized as early as possible so that existing weight conditions with regard to actual weight of the slices are maintained, in particular no more underweight slices are produced and/or the minimum average weight of the slices required for the entire batch is maintained.
