basis for competition and ensure we are better than competitive performance.
3. Lastly, when we need to look at practices for solving process performance problems, SCOR provides a quick
basis for analysis to ensure we’re starting out at least even with competitors.
Main issues still existing
- Business process re-engineering initiatives are not linked to reference models and develop their own and
isolated environment.
- Industry Best Practise and Benchmarking Information are hard to link to the own business.
- Process analyses are based often on company internal experts. What they know well can be analysed in
detail - what they don’t know remains in a black box.
How can we use the SCOR model
- The five distinct management processes link together (the chain in supply-chain) seamlessly from supplier to
customer – end-to-end.
- Standard language and standard nomenclature accelerates process understanding and definition.
- Depicts relationship between Supply Chain Partners, Suppliers and Customers.
- Incorporates industry best practices and metrics. …
Title: Openair-Plasma – Cleaning, activation and coating of modern aircraft materials

Nowadays, the highest demands are imposed on surfaces intended to reflect superior quality. From the semiconductor
industry through to the aircraft industry, surfaces ideally matched to the application in question are
needed so that production can proceed in systematic practical fashion without waste. Thus, plastics must be
activated prior to bonding and metals freed of oily contaminants; metal surfaces susceptible to corrosion, especially
in the aircraft sector, must be protected against environmental effects.
Pre-treatment methods used for these purposes include the cleaning of surfaces with solvents, fluorination and
chlorination of plastics, corona or low-pressure plasma processes and mechanical treatments. These methods,
however, are to varying degrees not capable of in-line integration, do not always yield reproducible results or
pollute the environment.
An atmospheric-pressure plasma system capable of in-line integration in numerous applications is presented.
This is based on plasma jets (Openair®-Plasma) which can powerfully activate plastic and metal surfaces. The
effects of the plasma have been demonstrated by ESCA studies and practical bonding trials amongst others on
carbon composites. Measurements over time of surface tension have shown that, depending on the material,
the surface effects achieved have good long-term durability. Furthermore, the possibility of plasma polymerisation
is examined. Chemical additives are mixed with the plasma and these are then deposited on the surface
in question. In this way metal surfaces can be provided with coatings which inhibit corrosion and aid bonding.
It has been shown by salt spray tests that the layers deposited, in particular on aluminium, have a very high
anticorrosion effect. The system is already being successfully employed in the sealing of aluminium engine
housings.

On account of its wide range of potential applications Openair®-Plasma technology is numbered among the
key technologies in surface treatment. It is already used today in practically all fields of industry to activate and
clean surfaces in order to improve the adhesion of glues and paints and to achieve better long-term durability.
Title: The technology of high-speed burnless deep grinding for parts from
hard-to-machine materials
Authors: Prof. S. Markovich
Time: November 5, 2009 12:10 pm
Room: Lumen
Now the most progressive method of grinding of parts from hard-to-machine materials is a high-speed deep
grinding. But this technique requires very expensive powerful high-speed special machine tools, expensive
high porous abrasive wheels and cutting emulsion containing surface-active substances. In addition, for today
there exists no solution to grinding burns problems for parts from hard-to-machine materials with formation of
compression residual stresses in a surface layer with deep grinding.
The offered technology is implemented with the special planetary-grinding head installed on a spindle of a
grinding machine. Thus usual grinding wheels and cutting emulsion are used. Provision of the fullest proceeding
of adsorption-plasticizer effect (APE) in the contact zone results in sharp decrease of cutting forces and contact
temperatures in the cutting zone. It excludes burns formation and provides formation of compression residual
stresses in a surface layer of a workpiece resulting in substantial increase of the part life.
The method allows to raise productivity of machining by 2-5 times and decreases consumption of cutting emulsion
