  1. Major Trends in Metrology – Utilizing Modern Multisensor Coordinate Measuring Systems Why multisensor? Status in Multisensor Coordinate Measuring system today Sensors Benefit Cost of ownership Major trends in Multisensor Coordinate Measuring system More functional gages More ease of use programming tools -> 1-3 DAY BASE TRAINING Software gets interchangable -> I++ Design-manufactoring-Inspection go together FDA compliant Feature based programming More custum gage user interfaces Uncertanty protocol (GUM)

  2. Who is QVI?QVI (with brands OGP, RAM, VIEW, KOTEM) delivers 35% of all multisensor systems per year world wide

  3. Why Multisensor? Status today: No single sensor can measure all parts !

  4. Video can measure: Diameters of chamfers Diameter of D at top of hole Focus points on A Focus points on E if: If you can “see“ it, you can measure it But what if you can’t “see” it? Tactile probing works best for measuring bore for size, form, and orientation Laser works best for surfaces (A,B) Status today: Multisensor Application Example Combination of Sensors Work Better

  5. Status today: Video probes Video Camera with part surface illumination Video image Measures • 2D contours by edge scanning • 3D topography by multifocus • edges • Arc‘s, Lines, circle • Hight (in z) part surface illumination

  6. Major trend: More Optical probes Different Surfaces Require Different Sensors White light laser high accurate surface points measurement deflectrometry Line sensor Area sensor high speed surface measurement Scratch detection on shiny surfaces High speed surface measurement High accurate edge detection

  7. Sensor Applications Especially Required for line and area sensors - Timeframe until 2015-2020 Why : can reduce metrology program creation time by 50 to 90% AND increases Accuraccy Impeller Cell Phone cover Turbine blade

  8. Great variety of probe tip diameters and stylus lengths Interchangeable stylus modules and change racks Status today: Tactile Probes Touch Trigger Very low force probe • Liquids, adhesives, Silicon wafers, • Contact lenses Interposer (fiber probe) • Very small diameter • High Speed Continuous Contact Scanning • Scan unknown surfaces • No prior knowledge of form required • Simply select start and end points • Solves complex 3-D challenges • Higher order curves • B-splines • Similar to video edge trace

  9. Status today: Comparison of Sensors Each Sensor Has Strengths and Weaknesses

  10. Status today: Advanced Multisensor production system Protection box Video Laser Part loading Video Tactile probe

  11. Higher productivity Fewer set-ups Faster cycle time Lower cost per part One system less costly than three or four Reduced training and calibration costs Maximum “data per dollar” Status today: Economic Benefits Multisensor Can Save Money

  12. Major trend: Investment comes from shop floor Much more ease of use required

  13. Major trend: Reduce Cost of ownership • Customers will only invest in machines where the cost of • ownership is less than today • How? • Software will be dramatically simpler to use than today • – CAD based Multisensor CMM -> base training • 1-3 day training

  14. Major trend: More Multisensor CAD based programming Advantage: - reduce programming cost - measurement is prepared before part is physically in existence

  15. Major trend: More Functional Gages (Fitting) less GD&T 3D functional gages (No Gauß) -> Immediate Visible Measurement results Advantage: - reduces cost for scrap - Speed up production Control - less training needed

  16. Major trend: FDA compliant Feature based measurement Select Features In Image Or List Resulting Protocol Advantage: - substantial reduction of programming time - worker selects Features to be measured - Training 10 minutes

  17. trend: Use existing technologies for metrology applications (example. copy machine) SCAN 200 (scan + Fit + GD&T) - easy to use on Shop Floor Advantage: - low cost 2D measuring system with GT&T

  18. Major trend: Integrate more special applications into Multisensor systems Gear measurement – optical and tactile Roundness, Roughness, forms Thread Cutter Thread Hob, cutter measurement – optical and tactile Advantage: - Less different metrology equipment required -> cost reduction

  19. Major trend: Design – Manufactoring – Inspecting go together by a NEW software concept SmartProfile I++ CAD Info from ANY CAD Systems create Result define Metrology Project - define Metrology - define points to measure GD&T Functional Fit per part GR&R manufacturing trend SPC Analysis I++ send points to measure Measured point Cloud control ANY I++ capable CMM - gather points

  20. Major trend: Protocol ResultStandards: Uncertainty in Measurement (Virtual CMM) New Advantage: accuracy statement for ALL measurements

  21. Major trend: Ease of use – by intelligent tools -will reduce cost
