ZRM Reference Measuring System
Referencing of Z0 levels of reference clamping systems for presses
and die sets
The use of reference clamping systems in the compaction process enables
the consistent work with Z0 reference levels from tool design over the
tool shop up to the press.
The Z0 level defines in the Z direction the reference level for the clamping
of the tools in the chuck. If the Z0-levels in the press are referenced
to each other, the filling, compacting and ejecting positions can be exactly
approached without any presetting in account of the tool dimension by
the press control.
The ZRM measurement system references via the precisely known punch
length the Z0 levels of the reference clamping system in the accuracy of
1/10 microns to each other.
Adaptation to new compaction tools are only done over transmission of
current punch lengths and the dunk and cut data.
The transmission of the tool and compaction data can be done manually
and automatically via identification system of the compaction tools (RFID,
ident code, ...). The control of the press calculates out of the tool data and
the reference data of the Z0 levels the new target values for filling,
compacting and ejecting. The control of the compaction orders, the management
of the geometry, the set up and process data can be done via a
process control system (COMPACTION ProGrit) or a database. Compensation
on the basis of tool rigidity (compression) and powder data can be
calculated and hand over to the press control on.
