Guiding principle
Punching and cutting is a method of processing sheet material. Using hardened tools (punch and die), the input sheet material is processed and the output is a cut part suitable for possible further workshop or other processing.
Sheet metal punching tools are most often used in the form of two-part tools (punch and die), which work on the principle of shearing. The separation of the material is caused by the penetration of the sheared edge into the sheet metal. The shear clearance between the tool and die causes partial separation of the material and subsequent tearing. This principle guarantees minimal burr on the split edge. The resulting accuracy and geometry of the hole copies the dimensions and shape of the punch and is in hundredths of a millimeter.
