                                                                             METROLOGY

OUR PROPOSAL
Alsace metrology offers services in dimensional control, in its laboratories or directly on-site, in
the goal to validate your products, your gauges, your tools, your moulds of production. We may
compare the measurement done to a plan or a numerical definition (CAD file...)
Actually, we are specialists in geometrical control : shape control (straightness, circularity), position
(location, concentricity, coaxiality), orientation (parallelism, perpendicularity).
We also propose global controls : deviation between a measured part and its CAD plan (IGES file
or compatible CATIA file).
Measurements are almost done in our laboratories, but our petrology specialists are available to do
this work with your equipment in your company.
To complete our service offer, we make calibration, instruments compliance tests, advice in
metrology, diagnosis and expertise.



TECHNICAL MEANS
We make use of :

             3D CMM WENZEL                                ROMER 3D Measuring Arm 180 cm
             Measuring column                             System to detect shape defects TALYROND
             Profile projector                            FARO 3D Measuring Arm 2,40 cm
             FARO Laser tracking system                   EPOCH4 Ultrasonic system



APPLICATIONS
 Dimensional controls, 3D measurements. Comparison with a CAD file, a plan, a reference part...

 Statistical analysis

 Tolerance analysis, location of geometrical defects

 Shape defects measurements : circularity, straightness, cylindricity, concentricity, parallelism,...

 Calibration

 Expertise on serial parts, compliance measurements

 Tools controls, end-line controls
    3D COORDINATE MEASURING MACHINE WENZEL
Our 3D machine works with the software
METROLOG XG.

The main features are :

   Measurement with a motorized contact head
   Capacity : 1600x1000x800 mm
   Accuracy : 3.2 + (L/300) µm
   Maximum weight : 2 250 kg

The control report may be a point cloud file (IGES
file format), result tables, imaged report (space
cartography) but it's possible to provide a specific
type of report.




    3D MEASURING ARM ROMER & FARO
                                            Our device enables making measurement with or without
                                            contact (laser head)

                                            The main features are :

                                               Laser or head mode
                                               Measurements in our laboratory or on site
                                               Accuracy (head mode) : 25µm or 43 μm
                                               Maximum size of the part : 1.8 m for Romer arm
                                                     & 2,40 ml for FARO arm

                                            The final report may be a point cloud file (IGES file format), or
                                            an illustrated document (presenting space cartography or 3D
                                            reconstruction).

    COMPLEMENTARY OFFER
  The shape defects device (maximum size parts Φ 300mm, h 300mm,
  accuracy 0.5 µm), the measuring column (maximum size parts h <1m,
  accuracy 50 µm), and the profile projector (accuracy 5µm), enable to
  characterize different products, to make dimensional controls, and to
  locate geometrical or form defects.
  FARO Laser Tracker : To control From 2ml up to 70 ml.
  Acurracy:in linear distance 3 μm up to 35 μm in the bad case
  EPOCH4 SOFRANEL: Ultrasonic system for contrôling defects and
  thickness.
Calibration and verifications : by mechanical comparisons, using comparators, exterior micrometers, bore
meters, callipers, depth gauges, etc. We dispose of many others technologies. Don't hesitate to submit your
problems, we are here to help you and to propose the technology tailored to your needs.
