Wedge cutting

In manufacturing technology, wedge cutting refers to the division ( pressing apart) of a material using one or two wedge-shaped cutting edges. This procedure is standardized in DIN 8588.

Possible types

Wedge blade on anvil

Knife cutting principle based on two differently shaped cutting edges

In the variant of knife cutting , the material rests on a suitably hard base and is pushed apart by moving a single wedge-shaped cutting edge.

An example of use is cutting through self-adhesive labels on their backing paper, which should be damaged as little as possible; The aim is to make it easier to later lift the labels at the edge from the arched, typically protruding carrier. A cookie cutter cuts a piece out of a thin layer of soft dough. Typically, holes are punched in thin, soft materials, such as a leather belt or a truck tarpaulin, with punch pliers or punches .

Principle of the bite cutting

When biting, on the other hand, the workpiece is located between two opposing wedge-shaped cutting edges that are moved towards each other and thereby push the material apart.

Tools that use this principle are side cutters , monier pliers , nail clippers , lever end cutters and bolt cutters .
