According to DIN 8583, indentation is the reshaping of the surface of a workpiece with a forming tool (e.g. stamp ) (often with a low feed rate ) and high pressure ( pressure reshaping ).

Indentation process

According to DIN 8583, there are fifteen different methods of indentation. They are further subdivided according to two criteria:

  • Processes with rectilinear movement of the tools and those with revolving (rotating) movement
  • Moving without sliding, i.e. without moving the tools over the surface of the workpiece (mostly perpendicular to the surface) and moving with sliding.
without sliding with sliding
Straight-line movement
  • Punching , pressing in with the help of a pointed tool, e.g. As for the landing and centering point for a drill to mark
  • Notches , using a wedge-shaped tool
  • Embossing , impressing relatively flat shapes in a surface, e.g. B. in the manufacture of coins
  • Countersinking , pressing in a molding tool to produce relatively deep shapes in a workpiece surface
  • Thorns , with a rounded tool
  • Piercing the low-waste producing a hole by two-sided mandrels
  • Hollow mandrels for creating a hole with a good cylindrical hole shape with a hollow mandrel that is pressed through the workpiece
  • Embossing straightening , indentation of a tool with raster- shaped elevations to produce flat workpieces
Circulating movement
