Splitting (procedure)
Splitting is a manufacturing process for dividing a workpiece using a wedge-shaped tool.
Differentiation to meaning
Forging technology
In forging technology , especially in open die forging , splitting has been the process of cutting a glowing piece of steel in preparation (pre-splitting) for punching (process) or for splitting material from the workpiece for further processing (e.g. forging ) for centuries until today by the blacksmith ).
In industrial production, the process is also known as wedge cutting .
Further understanding of process engineering
At the same time, in the course of history z. B. when working in quarries or logging a further understanding of the process engineering of splitting developed. The tool ( riving knife , axes , splitting hammers, etc.) usually does not pass through the workpiece completely, but only until the material breaks along the intended or specified dividing line.
This technology is mostly used in brittle materials or materials that have a grain or a generally anisotropic structure with preferred cleavage planes, such as wood or slate and other rocks . In addition, can also be cold - not heated - and thus brittle metals such as steel break before the tool for. B. a chisel has completely severed the workpiece.
