1 Trends in Manufacturing Metrology Fast, Accurate, Safe and Flexible Jochen Weinisch Carl Zeiss Industrial Metrology GmbH Regional Sales Manager China/Taiwan

2 System of Interchangeable Parts in Industrial Production 100 years ago: 2/3 of produced parts had to be manually adjusted to fit to each other Today: Separated production of parts, but all fit to each other during assembly WHY?? Because of global standards: nit System for a unique definition of product characteristics Machines for production according to the definition Metrology for determination and check of characteristics 2

3 Industrial Products What do these products have in common?

4 They stand for global boosters Electro-mobility Connection of fare apart places Resource efficiency Global communication and networking Mobility Energy Change in the energy market Health and fitness Globalization 4

5 Efects Megatrends like are the key driver of production trends Global megatrends Globalization Increasing Individualism Resource efficiency Energy Boundary conditions Climate change Demographic change Mobility Insecure trouble spots Trends in production Resource efficiency (energy, raw materials, capital) Flexibility (compensate market fluctuation, individualization) Transparency (predictability, directed quality control) New Processes (control of new processes) 5

6 Productions Trends and their Influence on Challenges and Trends in Manufacturing Metrology Trends of production Resource efficiency Flexibility Transparency New Processes Challenges and Trends in Manufacturing Metrology increasing integration reducing measuring time automatic data processing Fast reducing measuring errors / uncertainty verification of measuring uncertainty Accurate Safe increasing variety of measuring techniques increasing information density Flexible 6

7 Fast Lightning-fast systems make lightning-fast mistakes. Stanislaw Lem 7

8 Inetegration of metrology in production lines allows fast results Function Direct installation of CMM in production Integration into the automatic material and information flow Performance Fast adjustment to part variants by changing CNC programs without mechanical changes Comparable results to measuring room within temperature range: C 8

9 Fast trough intelligent Software in metrology Conventional 16 Scanning elements Complex programming Measurement time: 75 sec Fly-scan with Performance pack 1 Scanning element Simple and quick programming Saving: 69% of time / 52 seconds 9

10 Accurate Anyone who doesn't take truth seriously in small matters cannot be trusted in large ones either. Albert Einstein 10

13 Safe There is no safety in numbers, or in anything else. James Thurber 13

14 Safe: Conformity Evaluation, Tolerance and Measuring ncertainty "Golden Rule" "Decision Rule" (ISO 14253) The tolerance is not reduced if the uncertainty does not exceed % of the tolerance. The tolerance is reduced by the measurement uncertainty. Not OK Tolerance (Specification) OK Not OK (Small) exceeding of tolerance by the measurement uncertainty is allowed. Exceeding of the tolerance by the measurement uncertainty is not allowed. T- T T OT OT+ T- T T OT OT+ OT/T = upper/lower tolerance, = measuring uncertainty 14
