Classification of pairs – Guide pillars with slideways
Die clearance:
The die clearance largely depends on the requirements imposed by the metal
workpiece e.g. proportion of smooth zone to fracture zone and permissible
burr height. The material properties of the workpiece and the type and
condition of the machine used have also influence.
Criteria for selecting the play:
Die clearance; material thickness; type and condition of the machine used.

Workpieces with close tolerances and certain properties
of the cut contours; also thin materials.
Workpieces made of sheet metal thickness more
than 1 mm, preferably for follow-on composite tools.
Less stringent requirements with regard to edge definition;
cutting pressure and cutting work are distinctly
lower when working with a large die clearance than
when working with a small or medium die clearance.
