UP-Prosa
Problem: In the field of geometry and
dimensional metrology the inspection
characteristics of workpieces are verified.
These characteristics have specific values
and tolerances which are defined by
construction drawings. An example for
such a quality inspection is the test of
diameter and roundness of an engine
block’s cylinder bore.
Nowadays, various measuring devices
from different manufacturers exist. They
have different designs and measuring
technologies and therefore, almost
every manufacturer uses its own software
to control the hardware, evaluate the
measured data, as well as to record the
results.
Solution: At this point of development,
the research project UP-Prosa started,
aiming at the standardization of specific
parts of the whole intended production
process. It started with the design and the
definition of quality criteria and continued
with real measuring processes of individual
quality features of the workpiece being
manufactured. For this, the process of
generating the quality control plan as well
as the coding of measuring programs
was simplified. Concerning the programming
of geometric measuring devices,
a complex platform was planned and
almost completely realized that allows
controlling different geometric measuring
devices with one uniform user interface.
To control the measuring device via
the user interface a communication
protocol was designed. This protocol
transmits general information and includes
universal commands for moves and
measurements to be used with different
geometric measuring devices.
At the level of geometric measuring
devices a universal controlling software
named Prosa InterCommunicator
(Prosa-ICom) was designed. Prosa-ICom
communicates via network with the user
interface and translates the defined
protocol into a measuring device specific
form. The internal structure is extendable.
Thus it is prepared for both new developments
and upgrades (retrofit) of all kinds
of geometric measuring devices.
Product: To spread the results of the
project a unit-type “UP-Prosa-Retrofit
Package” was composed. It is intended
to be used with new and old devices and
combined sensor systems. The package
contains user guides and source codes
to extend the graphical user interface
and to connect ”Prosa-ICom” to your own
device. The package is available at a
service charge via the international business
platform EVIGeM (www.evigem.org).
The UP-Prosa platform merges the
whole geometry and dimensional
metrology and simplifies the handling of
inspection processes. This aggregation
leads to unified interfaces of different
measuring devices with their specialized
sensors.
Project: The Innonet-Project UP-Prosa
was funded by the German Ministry
for Economy and Labour (BMWA) and
coordinated by BIBA at the University of
Bremen/Germany.
