Machine Reference Measurement

Since the release of Version 8.0 in 2001, the CEUS software platform has become established among nearly all automobile manufacturers in Europe and North America as the standard platform for online risk management for bolted assembly operations.

In close cooperation with users in the automotive industry, Version 8.1 has been developed with expanded capabilities and improvements to meet emerging new requirements.
CEUS 8.1 helps make test and inspection processes for bolted assembly operations more reliable and easier, and it also helps simplify planning, management and documentation activities.

The latest new feature is machine reference measurement (MRM).

This testing strategy enables users to conveniently and efficiently determine the proper machine calibration values for controlled drivers. MRM is a testing strategy that is tied into the tool or machine and allows the actual machine value to be conveniently and quickly compared with an associated reference value determined by a second, independent measurement system.

This new function is fully integrated into the CEUS 8.1 data environment, so existing structures and master data sets can be used without any changes in measurement procedures. The seamless documentation is automatically merged into the CEUS database system to allow calibration value monitoring to be easily verified with the user's own testing strategy.   

The MRM testing strategy can also be included in tool-based CEUS test planning. It involves either making check measurements on tools and machines using process simulation or placing an additional, independent sensor between the drive output shaft and the workpiece for measurement at the process location.

If the MRM testing strategy is enabled during measurement operations, both values (the actual machine value and the reference value) are acquired and documented. The deviations in both values are calculated and evaluated in accordance with the specified limits in the master data set. Violation of one or more limits results in a NOK evaluation of the MRM in the test plan, certificate and documentation. The percentage deviation of the average values is shown for correction of the machine calibration values.

The user can enter the current machine value in order to have the system calculate the new, corrected machine calibration value.
